Process_Description:
Modified html.c to cope better with titles that span more
than one line. The separate lines of the title are
concatenated for both the document title and the top-level
heading.
Process_Step:
Process_Date: 19950223
Process_Description:
Modified html.c to always output two spaces after the
</em> tag in a keyword.
Process_Step:
Process_Date: 19950320
Process_Description:
Modified sgml.c to use eight-character tags that are
different from the ASTM tags. The ASTM tags cannot be
used in sgml because many are ten characters long, and
SGML names are restricted to eight characters.
Created a new module astm.c containing the ASTM tags, Z39.
50 numbers, and the code to go between those and FGDC
keywords. This module is not currently linked into the
executable.
Process_Step:
Process_Date: 19950403
Process_Description:
Modified astm.c to include tags for map projection names
taken from Doug Nebert's DTD:

Excised sgml tags from sgml.c; transferred the eight-
character tags to a new file called ps8.c. Choice of tags
to use in generating SGML output is governed by a local
variable called do_astm in sgml.c; currently this is
always set to 1, causing the astm tags to be used.
Process_Step:
Process_Date: 19950425
Process_Description:
Modified syntax.c to issue warning rather than error when
a scalar value is missing, and to include text of unknown
keywords in error messages.
Process_Step:
Process_Date: 19950526
Process_Description:
Modified text.c to not output the error message about too
much indentation. The code already functions correctly
for files that are indented consistently within sections.
Process_Step:
Process_Date: 19950526
Process_Description:
Modified text.c to output a warning if the indentation
is ambiguous, as in
A:
B:
C:
D:
Here the parser assumes that D is a member of A, not of
B. But the user might have intended D to be a member of
B. The parser cannot tell, so it issues a warning.
Process_Step:
Process_Date: 19950531
Process_Description:
Modified mp.c to add functions for node handling:
void deallocate_item (struct item *p);
struct item *insert_item_after (struct item *r);
struct item *insert_item_before (struct item *q);
struct item *add_child (struct item *p);
and added comments explaining these functions.
Added code to main in mp.c to insert a parent Metadata
node if one is not already present. This causes the
syntax checker to report missing major sections that are
required.
Process_Step:
Process_Date: 19950610
Process_Description:
Created module extend.c to handle lookup and translation
of local element names (i.e. element names not part of the
FGDC standard). Modified keyword.c to allow the functions
key_of and text_of to return valid data when extensions
are given as their arguments. Modified astm.c and ps8.c
to report as the sgml tag of an extension the tag name
returned from text_of_extension() in extend.c. This is
not entirely satisfactory, because extensions might be
structured like FGDC keywords, i.e. a long form for
textual reports and a short (8- or 10-character) tag name
for sgml.
Process_Step:
Process_Date: 19950622
Process_Description:
Added functions in html.c to handle translation of
reserved characters in html output. This converts
theURL in the input to
<a href="theURL"><tt><URL:theURL></tt></a>
in the output, thus activating URLs embedded in the
metadata. It also converts other occurrences of < and >
to < and > respectively. This is not necessarily
desirable in all cases; there is an internal variable
called do_text_translation that controls whether or not
this gets done. If do_text_translation is set to 0,
textual values are conveyed to the html file as they
appear in the input file. If do_text_translation is
nonzero, textual values are translated as described.
Process_Step:
Process_Date: 19950623
Process_Description:
Added code to text.c, syntax.c, html.c, and sgml.c to
handle blank lines. Modified item structure to include a
prev pointer within compound types.
Process_Step:
Process_Date: 19950626
Process_Description:
Modified html.c to correctly skip the Metadata tag at the
top of the tree. Added code to correctly handle
ampersands and double-quotes.
Process_Step:
Process_Date: 19950626
Process_Description:
Modified text.c to handle blank lines in a more logical
and comprehensive fashion. Blank lines are now assigned
indentation prior to the disruption of links that forms
the overall parse tree. Indentation assigned to a blank
line is the larger of the indentation of the previous non-
blank element or the next non-blank element in the file.
This ensures that blank lines will not have children (if
they did, the children would not appear in the output) and
only occur as members of lists.
Process_Step:
Process_Date: 19950627
Process_Description:
Created config.c and config.h to handle configuration
issues through a configuration file, containing key words
in the same general form of the metadata. Modified mp.c,
text.c, html.c, and sgml.c to consult the information
contained in the config file.
Process_Step:
Process_Date: 19950630
Process_Description:
Created local.c to replace extend.c for handling local
extensions to the standard. This module provides a
mechanism for user-specified element names, with
corresponding SGML tags, to be handled properly by the
parser and by the code generators. Syntax checking is
relatively primitive, and is based a parent list and child
list associated with each local element. Essentially this
means that local extensions are always optional and
repeatable and their children, if any, are always optional
and repeatable.
Process_Step:
Process_Date: 19950630
Process_Description:
Modified sgml.c and html.c and config.c to allow users to
specify a string that will be output wherever blank lines
occur in the input file. The default for SGML is ""; the
default for HTML is "<P>\n". This option is specified by
putting the keyword blanks under the keyword sgml or html
under output in the configuration file.
Process_Step:
Process_Date: 19950711
Process_Description:
Modified ps8.c to reflect the following tag name changes:
tempkeyt -> tempkt
accscons -> accconst
accsinst -> accinstr
columns -> colcount
vertcnt -> vrtcount
Rebuilt makedtd and rebuilt ps8.dtd.
Process_Step:
Process_Date: 19950714
Process_Description:
Modified config.c to allow the keyword skip_extensions
under output:sgml. Modified sgml.c to look for this
keyword in the configuration info. If present, then
elements that are not part of the 19940608 CSDGM will
not be included in the sgml output.
Process_Step:
Process_Date: 19950926
Process_Description:
Modified sgml.c to make 8-character tags the default,
as specified in the GEO attribute set for Z39.50.
Process_Step:
Process_Date: 19951101
Process_Description:
Modified mp.c to remove the generic tree-handling
routines to tree.c, which was added to the Makefiles.
Process_Step:
Process_Description:
Modified syntax.c to permit more than one
Entity_and_attribute_Overview in an Overview_Description.
Thanks to Chuck Stein for pointing out this bug.
Process_Date: 19960201
Process_Step:
Process_Description:
Modified config.c to correctly recognize the component "top_level"
of "text"; this controls whether the top-level Metadata element
is preserved on output or omitted.
Process_Date: 19960215
Process_Step:
Process_Description:
Modified html.c and config.c to allow new syntax for specifying
the prefix and suffix tags of element names and element values
in html. The new syntax is
output
html
element
name
prefix <html code>
suffix <html code>
value
prefix <html code>
suffix <html code>
This allows specific html code to precede and follow both the
element name and the element value. Created a new file called
deluxe.cfg in doc that shows how this new syntax can be used
to link every element name back to the correct section of my
hypertext rendition of the standard.
Process_Date: 19960328
Process_Step:
Process_Description:
Modified astm.c to remove the information about z39.50 numbers.
Added the module z3950.c to carry this information appropriately,
and modified local.c to allow users to include in the description
of extensions a characteristic z3950 whose value is the numeric
tag assigned to the element.
Process_Date: 19960405
Process_Step:
Process_Description:
Modified html.c to fix bug in which default prefix for element
names was taken to be "prefix", and default suffix "suffix".
Thanks to Hugh Phillips for pointing this out.
Process_Date: 19960521
Process_Step:
Process_Description:
When a line in a text value was indented relative to those preceding it,
the line was correctly recognized by the parser as being a part of the
textual value. But when such an indented line immediately followed a
blank line, the indented line was considered a sibling of the blank and
a child of the preceding text line. This caused the line to be omitted
from the output. Not good. The fix is to modify check_unknown in
syntax.c so that this case is recognized and the topology is rearranged
to fit the situation.
I'm not sure whether this is the right place to fix this problem. I think
we could also fix it in the parser, by assigning the indent value of lines
that follow blanks differently if the preceding nonblank line has key
Wunknown. This would require more sophisticated look-back at that point
in the parser, however, and I don't know whether it would correctly
handle more complicated situations.
Process_Date: 19960623
Process_Step:
Process_Description:
The code described in the previous process step has been excised. Instead,
the function equalize_indented_scalars was added to try to fix up textual
values that have indentation. The basic problem is that you don't want
blank lines to be parents of text values, nor for that matter do you want
text values to be parents of text values. This code is not comprehensive,
and probably needs more work.
Process_Date: 19960629
Process_Step:
Process_Description:
Modified main() in xtme.c, mp.c, and cns.c to read more than one
local extensions file. This should enable people to choose more
carefully which extensions will apply to a given input file.
Process_Date: 19960705
Process_Step:
Process_Description:
Modified equalize_indented_scalars() in text.c to avoid writing
into p->next->prev when p->next is NULL. Modified sgml.c to
avoid warning on some systems casting char * to unsigned char *.
Process_Date: 19960719
Process_Step:
Process_Description:
Modified all source files containing #ifdef's so that these preprocessor
directives occur only at the beginnings of lines, to work with non-standard
compilers such as the one supplied with OSF/1. The ANSI standard came out
in 1987. Haven't these vendors *read* that document by now?
Process_Date: 19960806
Process_Step:
Process_Description:
Modified html.c to remove the default formatting of elements. These
should be controlled by a configuration file. Also modified this file
so that it correctly recognizes when no value is given as the default
prefix or suffix of element names.
Process_Date: 19960806
Process_Step:
Process_Description:
Modified config.c to recognize and html.c to use the configuration
element output:html:element:value:obeylines which, when present,
causes html.c to append a line break <br> to each line of the value
of the specified element.
Process_Date: 19960806
Process_Step:
Process_Description:
Modified text.c to output {single scalar followed by blank} the same
way as {single scalar}; immediately following the element name.
Modified syntax.c to strip enveloping quotes from scalars that have
restricted domains.
Process_Date: 19960809
Process_Step:
Process_Description:
Modified syntax.c to limit the number of Enumerated_Domain to one per
Attribute_Domain_Values. This bug spotted by Gerry Daumiller.
Process_Date: 19960826
Process_Step:
Process_Description: Modified syntax.c to not test blank lines in scalar values.
Process_Date: 19960906
Process_Step:
Process_Description:
Modified sgml.c to include a rudimentary SGML parser. It has
essentially no flexibility and no error recovery.
Modified mp.c to use this SGML parser if the input file's name
ends with .sgml or .sgm (case not sensitive).
Process_Date: 19960907
Process_Step:
Process_Description:
Modified sgml.c to swat bug. If a configuration file was used and
the output:sgml:blanks was also used, a seg fault could occur.
Process_Date: 19960918
Process_Step:
Process_Description:
Modified config.c to recognize options output:html:header and footer.
Modified html.c to output text of header before the title in the body
of the html, and to output text of footer after the "generated by mp"
line at the end of the html.
Process_Date: 19960926
Process_Step:
Process_Description:
Modified dif.c to output a newline where Wblank appears in the parse tree
rather than "(blank):"
Process_Date: 19960927
Process_Step:
Process_Description:
Modified syntax.c to classify errors and maintain counts of six different
kinds of errors: unrecognized elements, misplaced elements, missing
elements, superfluous elements, empty elements, and elements with the
wrong sort of values. Modified mp.c to write a one-line report to stderr
showing the number of each type of error.
Fixed a bug in syntax.c that caused the less-than-intuitive error message
"(unknown) is not permitted in <element>". The new text is more informative.
Process_Date: 19960930
Process_Step:
Process_Description:
Modified config.c to fix bug in unify_strings() where allocated block dst
was not initialized before a call to strcat (crashed on Linux).
Modified sgml.c to output Eric's suggested public identifier for DTD 1.0.
Process_Date: 19961017
Process_Step:
Process_Description:
Modified config.c to understand element 'body' in output:html; the
text given for 'body' will be appended to the <body> tag in the html
output, allowing the user to specify background color for the html.
Process_Date: 19961028
Process_Step:
Process_Description:
Modified keyword.h to define the values of enum fgdc_keyword, so that
binary files will have more of a chance at portability. Modified
config.c to recognize the element "binary" in the config file. Modified
mp.c to read and write binary files on request. Added module binary.c
to carry out encoding and decoding of binary files.
Process_Date: 19970108
Process_Step:
Process_Description:
Modified decode_tree() in text.c to allow scalar elements to begin
on the line that contains the element name.
Process_Date: 19970130
Process_Step:
Process_Description:
Modified write_contact_info() in dif.c to use more stack space for
lname, mname, and fname (was 32 bytes in each case).
Process_Date: 19970317
Process_Step:
Process_Description:
Modified write_html() in html.c to allocate more scratch space for
the title. This caused rare crashes that could not be easily
anticipated or duplicated because they depended on the granularity
of heap space, on the number of lines in the title, and on the
lengths of the title lines.
Process_Date: 19970401
Process_Step:
Process_Description:
Modified parse_sgml() in sgml.c to not aggregate lines in the input.
Modified write_html_item() in html.c to use <dd> for single-item
data values of length 64 or greater. Previously these would be
put into the <dd> tag. Modified translate() in html.c to use a
managed dynamic buffer rather than a static array.
Process_Date: 19970507
Process_Step:
Process_Description:
Modified parse_sgml() in sgml.c to fix bug in which unrecognized SGML
tags were not processed properly. Changed parse_sgml() to permit
execution to proceed when unrecognized tags occur. Added code to
decode ISO 8859-1 entities in incoming SGML text.
Process_Date: 19970519

Process_Description:
Modified print_item() in tree.c to fix bug--was missing the variable
to be printed in one of the printf calls.
Process_Date: 19970610
Process_Step:
Process_Description:
Modified parse_sgml() in sgml.c to not output the warning about
extraneous text if the extra text is entirely composed of whitespace.
Process_Date: 19970708
Process_Step:
Process_Description:
If you specified the html prefix or suffix for an element value but
not for the element name, it didn't use the default element name
prefix and suffix, it used nothing. In this change html.c was modified
to use the default name prefix or suffix if the output:html:element:name:
prefix or :suffix are not specified. If ...:name:prefix is specified
but is blank, then the default name prefix is not used. This allows
you to specify that no prefix be used even if there is a default prefix
(same for suffix).
Process_Date: 19970821
Process_Step:
Process_Description:
Modified keyword.c, config.c, and local.c to avoid overflowing the
local variable string when trying to recognize an element name.
Process_Date: 19970912
Process_Step:
Process_Description:
Modified config.c to recognize preformat and meta elements under
output:html. preformat causes <pre> tags to enclose sections of
textual values whose lines all begin with >. To use a different
character, give it as the value of preformat. It is on by default,
so specify "preformat off" to disable this feature. meta enables the
generation of dublin-core meta elements in html output. It is
on by default. To disable dublin-core metadata, use "meta off".
Process_Date: 19971031
Process_Step:
Process_Description:
Modified write_html_item() in html.c to simplify code and properly
preformat all sections preceded by >.
Process_Date: 19971106
Process_Step:
Process_Description:
Modified write_html_item() in html.c to not display the preformat
indicator character in preformatted sections.
Process_Date: 19971112
Process_Step:
Process_Description:
Modified key_of_ps8_tag() in ps8.c and key_of_astm_tag() in astm.c to
call a new function extension_of_sgml() in local.c that returns the
key of a local extension. This causes mp and stomp to recognize
extensions in sgml input as well as in text input, using the same
mechanism. Thanks to Lisa Peoples for helping to find this bug.
Process_Date: 19980114
Process_Step:
Process_Description:
Modified html.c to translate bare URLs into live links. This recognizes
ftp://url and
http://url as forms of urls as well as the older format
<URL:theURL>. Note that <
http://theURL> will now become live as well.
Process_Date: 19980217
Process_Step:
Process_Description:
Fixed minor bug in text.c. If a textual value began on the same line as
the element name but that line was followed by a blank, it always discarded
the text following the element name. Workaround was to close up the
blank line. It now looks foward in the list of elements to the next
non-blank element; if that is Wunknown or EOF, the text following the
element name is retained as part of the value of the element. If the
next non-blank line is a recognized element, the text following the
original element name is discarded with a warning.

assisting in this upgrade.
Process_Date: 19980316
Process_Step:
Process_Description:
Modified write_html() in html.c to place the name tag around only
the <hr> at the top of each major section. The concern was that
poor parsers of HTML might not properly match the </A> with the
most recent <A ...> tag, which would result in an error where links
appear within major sections. Thanks to Curtis Price of USGS WRD for
pointing this out.

Process_Description:
Renamed metadata.dtd as csdgm1.dtd, copied into file csdgm2.dtd. Modified
csdgm2.dtd to reflect syntactical structure of version 2 of the CSDGM.
Added a file "catalog" to relate public identifiers to the SGML files
included with the software, tested with nsgmls on one metadata record.
Updated sgml.c to produce a DOCTYPE that refers to the version 2 DTD.

Process_Description:
Created a new module fixdoc.c designed specifically to fix some specific
problems created by DOCUMENT. Used in conjunction with a set of local
extensions, assuming also that cns has been run on the output of DOCUMENT
FILE using the same local extensions (and some aliases). This is a fairly
complicated procedure but one that I hope will save people from a lot of
aggravation as they try to recover the information they entered using
DOCUMENT.

Process_Description:
Modified local.c to properly handle cases where more than 64 extensions

Modified upgrade() in upgrade.c to avoid following bad pointers when
decoding G-Ring polygon data. This bug arose when users ran mp on
the template, which has no data.
Process_Date: 19981124
Process_Step:
Process_Description:
Modified config.c to include option "prune" within "input". This causes
mp to prune the whole tree after fixdoc and upgrade. Not that anyone
should do prune in combination with fixdoc, but that's where it is in
the code. Default is not to prune.
Process_Date: 19981130
Process_Step:
Process_Description:
Modified mp.c to strip common extensions off the input file name when
composing output file names from templates specified in the config
file. This means that if you specified in your config file:
output
errors %s.err
html
file %s.html
and process the input file "stuff.txt", the errors will be put into
a file called "stuff.err" and the html output will be put into a
file called "stuff.html". The file option can be specified for
html, sgml, xml, text, and dif output, and has the same effect in
each case.
The extensions that will be stripped from the input file name are
currently only the following, upper or lower case:
.txt
.sgml
.sgm
.xml
.text
.met
.bin

Process_Description:
Modified config.c to recognize the keyword "ext" under "input". That
element, which may be repeated, is used to indicate the file extension
used for the input metadata file. This allows the user to expand the

Process_Step:
Process_Description:
Modified html.c to add a new function write_html_faq(), which like the
function write_html(), writes an HTML output file. The "faq" version
casts the metadata in the form of a FAQ list. FAQ here stands for
Frequently Anticipated Questions rather than Frequently Asked Questions,
since we have no way to know whether anybody will actually ask these
questions, but at least we think we can answer them! ;-)
At this writing (19990217) it works on all the examples but doesn't
handle more than a few of the questions, and so leaves out quite a bit
of the metadata. Expect changes soon.
Process_Date: 19990217
Process_Step:
Process_Description:
Modified sgml.c to recognize the entity "&break;" while parsing sgml.
When it finds this entity, it will add a Wblank element after the
text in which the entity was found is converted into a Wunknown. So
if the line contains nothing beyond the "&break;", the Wblank will
be inserted where the "&break;" is. If any text follows the "&break;"
on the same line, the Wblank will be inserted after that text.
This allows people who are using sgml as input to specify where blank
lines should occur within text values, since in sgml blank lines are
normally ignored.

Process_Step:
Process_Description:
Modified many of the C source files so that they do not explicitly
declare the functions stricmp and memicmp, but instead include a new
header file stricmp.h that declares these functions. The header file
stricmp.h wraps the declarations in conditional code. If the system
on which you want to compile already has the function stricmp, for
example, then define the symbol HAVE_STRICMP in the CFLAGS of the
makefile. Likewise if your system already has memicmp, define
HAVE_MEMICMP.
Also I modified the declaration of memicmp to match that given in the
mingw32 headers; specifically I made its pointer arguments to be of
type const void * and its integer argument to be size_t instead.
This was all motivated by my discovery that I could compile using
the cygwin tools on Windows NT but specify -mno_cygwin and thereby
not need to pack the cygwin1.dll into the distribution.

Modified upgrade.c so that when it changes the value
of Metadata_Standard_Version to FGDC-STD-001-1998, it also deletes
any additional children of Metadata_Standard_Version. This occurred
when people had multiline responses for Metadata_Standard_Version,
which is caused by wrapping the element's text to the next line.

Modified translate() in html.c to encode high-bit characters using

contradictory, but maybe it won't hurt, and anyway we can always
undo the first change and stick the character codes in as is.

This causes relative links to work when the html document is retrieved
through the clearinghouse (otherwise those links are relative to the

Process_Description:
Modified write_text() and write_text_item() in text.c to output an
element prefix if one is specified in the config file. So if the
config file contains output:text:prefix, then its contents will be
output immediately preceding every element name in the text output.
This would be helpful if a user wanted to allow an unsophisticated
person edit the text file before re-processing with mp. The trick
is that if you put a strange prefix like @@ before each element name,
then you can run cns on the edited file, and this makes it easier for
cns to distinguish an element name from a text value that starts with
one of the element names. (2.4.12)

Process_Description:
Modified xml.c to output the elements in the order given in actions.c
This is necessary because although mp does not require elements to

in which the order of elements is not significant but the elements
themselves are. (2.4.13)

Process_Description:
Modified xml.c to read and store attributes of XML elements read as

Process_Description:
Modified html.c to encapsulate the code that creates links to related

looks at the configuration for a section "output:html:link". Within
that section, if there are any of the elements link_faq, link_html,
link_text, link_sgml, link_xml, or link_dif, then a link line is
written to the output HTML file. For each link_type element, if a
value is given it is taken as the URL for the link to the related file,
with %s in the value being substituted for the name of the input file,
not including its extension or its path.

Modified xml.c to parse the whole XML input file at once rather than
one line at a time. This permits start-tags that have attributes to

still assumes that the input data are ISO-8859-1; this is not good
because XML uses UTF-8 by default.

Process_Step:
Process_Description:
Modified write_links() in html.c to better handle the case in which
the input metadata are in directories other than the one from which
mp is run. It was implicitly duplicating part of the file path,
because the HREF given in the BASE tag contained some of the path
elements also present in the value returned from related_file().
The problem shows up only if you specify a BASE tag in output:html
and you don't specify a value for link_faq, link_html, link_xml, etc.
The current code still won't work well if you specify a BASE tag but
you try to put the various output files in directories other than the
one that contains the input file. If you want to put alternative
output formats in different directories, you must use the config
options link_faq, link_html, link_xml, etc. (2.4.24)

is an integer 0 or 1 that gets set to 0 by default and then gets set

Process_Description:
Implemented word-wrap in mp's text output. Added functions
wrap_text() and wrap_subtree() to tree.c. Modified config.c
to recognize config word "wrap". Modified write_text() in
text.c to look for "wrap" within output:text, and if the value
given is greater than zero, to wrap all text values to that
width. For example,
output
text
wrap 72
in the config file causes all text in the text output file to be
wrapped in paragraphs so that it fits in the first 72 characters
of the page. This all assumes 2-space indentation in the text
output, which is the default. I also had to modify mp.c to call
write_text() last among the output formats so as not to muck up
any of the other formats. (2.4.34)
Process_Date: 19991104
Process_Step:
Process_Description:
Modified write_xml() in xml.c to not include a DOCTYPE declaration by
default. Modified config.c to recognize the element "doctype". If
specified under output:xml, the value associated with "doctype" will
be output after the XML declaration. Typically that will be a DOCTYPE
declaration, but you could really screw things up and use something
else instead. If the config file has an empty element output:xml:doctype,
then the default DOCTYPE is output.
Modified xml.c to not encode characters on output. When XML is input,
the default encoding is assumed to be UTF-8. That can be overridden
on input by specifying the encoding in the XML declaration. When
plain text or SGML is input, the default encoding is ISO-8859-1.
Either way, characters above &127; are output AS IS in XML, and the
only characters that are encoded as entities are <, >, and &. (2.4.35)

Modified xml.c to fix bugs in parser's handling of comments and

Process_Step:
Process_Description:
Modified decode_text() in config.c and in local.c to explicitly look for
and then disregard comments. Here a comment is any line whose first
non-blank character is the pound sign (#). This change keeps comments
from disrupting mp's understanding of the indentation of the config file
and the extensions files, so that, for example, if you have
output
html
# this is a comment; note that it is indented less than the
# element immediately above it.
file %s.html
faq %.faq.html
Then the "file" and "faq" elements will now be properly recognized
as children of the "html" element. I think it used to consider
them children of the comment, and thus were silently ignored.
I bumped all minor version numbers by one for this fix. (2.4.40)

Process_Description:
Significant modification of memory management in all programs. In tree.c,
the allocate_item() and deallocate_item() routines have been replaced

fixed a number of less obvious bugs in the code, particularly in text.c.

Process_Date: 20000128
Process_Step:
Process_Description:
Introduced a new program "mq", built from guts of mp and tkme. This
program reads a Tcl script provided by the user and executes it. In
addition to the standard Tcl language, the following procedures may
be called:
read_config <config_file>
parse_text <input_file>
find_first <element_name>
find_in <address> <element_name>
find_next <address> <element_name>
value_of <address>
forget
find_first returns the address of an element in hex. This should not
be modified, but should only be used as input to find_in, find_next,
and value_of. forget causes the entire metadata record to be removed
from memory, so you can read another record. (mq 1.0.0)
Process_Date: 200001
Process_Step:
Process_Description:
Major change to mq. The syntax is now more like that of Tk widgets:
read_config config_file
This command reads a standard config file, which will apply to all
metadata read in this Tcl session. You can read only one config file,
and you have to do it before you read any metadata.
metadata m -parse input_file
Here m is a Tcl variable name. On output it is given a unique
value that allows mq to keep track of it. This command returns 1 if
the parsing was successful, 0 otherwise.
$m find_first element_name
Here m is a Tcl variable previously passed to the metadata command
above, and element_name is a standard or extended element name.
This command returns the address of a matching element in hex, or
zero. Use the address in subsequent commands.
$m find_in address element_name
Here address is the value returned from the find_first subcommand
above or a similar subcommand below. If the given address is an
element whose name matches the target element_name, the same address
is returned. Otherwise it returns the address of the first child,
grandchild, or more distant descendant node whose name matches the
target element_name.
$m value_of ?-nonewline? address
If the address given matches a data element, this returns its value
as a string. If you specify -nonewline, then it comes as one line,
with each line separated by a single blank space. Otherwise each
line is separated by the newline character (ASCII 10).
$m contains address
This returns 1 if the address corresponds to one of the elements in
the tree, 0 otherwise.
$m name address
This returns the name of the element at the given address.
$m next address
$m prev address
$m parent address
$m child address
These subcommands return the address of the next, previous, parent,
or child node in the tree, relative to the given address. Zero is
returned if there is no corresponding element. These provide a
way to walk through the tree manually.
$m forget
This frees all of the memory used for a metadata record. I cannot
recommend using the Tcl command unset; it seems to take a long time
to complete.
Note that this interface allows you to read and manage more than
one metadata record at a time. If you're going to read a lot of
records, you will probably want to use the unset command when you're
done with each one.

Process_Step:
Process_Description:
Modified mq.c to express the config-file handling in a different and
more useful way. Now we have the following commands
config read config_file
reads the named config file, returns 1 if successful, 0 if not
config find_first option
returns the address of the named option in the config tree. This
is something you use in other config commands.
config find_next address ?option?
returns the address of the next option after the one whose address
is given as the address argument. If no option name is specified,
it looks for an option with the same name as the one whose address
is given.
config find_in address option
returns the address of the first option of the given name that is
within the subtree headed by the node at the address given.
config value_of address
returns the value of the option at the address given.

was present, passed its address, rather than the address of its child
Citation_Information, to write_citation() for formatting. The result
was that no Larger_Work_Citation elements were being output. (2.5.2)
Process_Date: 20000217
Process_Step:
Process_Description:
Modified mq.c to include some new functions:
value_set <address> <text>
This assigns the given text to the element at the address given
if that element can contain a value. An error is reported if the
address is that of a compound element.
insert ?-before | -after | -child? <address> ?<element>?
An element of the specified type is added to the tree before,
after, or as a child of the element whose address is specified.
If no placement is specified (that is, neither -before, nor
-after, nor -child is given), the element is added as a child
of the node whose address is specified. This function does NOT
check to see whether the element so inserted is permitted to be
there by the FGDC metadata standard.
delete <address>
The element at the specified address is removed from the tree and
cannot be recovered.
copy <address>
A copy of the element at the specified address is made and its
address is returned as the result of this operation. The copy
has no links upward, forward, or back, and can thus be attached
to any other metadata record using the paste function.
paste ?-before | after | -child? <address> <subtree>
The subtree given as the final argument is attached to the current
metadata record before, after, or as the last child of the element
at the address given. This works only if the address argument is
a compound element in the tree.
write ?-format text | sgml | xml? <filename>
The metadata record is written out to the disk file whose name is
specified as the final argument. If no format is specified using
"-format <format>", then the format is text unless the output file
ends with ".sgml" or ".sgm" or ".xml" in which cases the file will
be written as SGML or XML.

Process_Description:
Modified process_metadata() enabling a -list option to the function
value_of. When value_of is used with -list, the result is returned
as a list of lines rather than as a single block of text. It makes
no sense to have both -list and -nonewline, so writing the value_of
command with both options results in an error.
is_compound <address>
This function returns 1 if the element at the address given is a
compound element, and 0 if the element is not compound. (mq 2.3.1)

Process_Description:
Modified html.c to use write_html_value() instead of a simple munge() for
the text associated with a Browse_Graphic_File_Description. In most
cases, this text is short and unadorned and a simple output would do
fine. However if the metadata writer put any >'s in the value, they
should be respected as preformat indicators. (mp 2.5.4)

Modified xml.c to write the apostrophe out in XML as ' and the
quotation mark as ". Modified entities.c to include these
symbols in the ISO-8859-1 encoding table, so they are generated in
the SGML output and recognized in SGML input as well. Archie Warnock
indicates some XML or SGML parsers need the apostrophe and quotation
marks to be encoded in this manner. (mp 2.5.5)

Modified xml.c to call strcpy() rather than decode_entities() because

Added direct support for the Biological Data Profile

Process_Date: 20001006
Process_Step:
Process_Description:
When I included the bio profile elements, I made it impossible
to use the same elements as extensions even when the bio
profile was not being used. This is because the bio profile
elements are kept by mp in the same bucket that it uses for
standard elements, and you can't use an extension that has the
same name as a standard element. Some of my geological data
sets use the geologic age extensions, which are taken from the
bio profile, but they don't use the rest of the bio profile.
One solution would be to simply use the bio profile for
these records. In this case the geologic age elements are
recognized properly, but a spurious error message is generated
because the bio profile includes one mandatory element,
Description_of_Geographic_Extent within Spatial_Domain.
The missing element is flagged as an error.
The correct solution is for mp and friends not to know the
bio profile elements unless the bio profile is used by
choice. That way the same elements can be introduced as
extensions in the usual way. So I modified keyword.c
and made some changes to the main programs as well, to
introduce a function use_element_names (language,profile).
This function selects standard element names using the
requested language, and adds to them the profile element
names (any profile you want, as long as it's the bio
profile). (mp 2.7.1) (mq 2.5.1) (cns 2.6.1)

Modified mq.c to enable commands detach and attach. $m detach $p
detaches the element p from the metadata record m. $m attach $q $p
attaches the detached element p to the metadata record m as a

$m attach ?-child | -before | -after? <address> <detached address>

Process_Date: 20010420
Process_Step:
Process_Description:
Modified write_xml_item() in xml.c to examine the static
variable element_order when writing the children of an
element. element_order is an enum that can be either
STANDARD or ASIS (in future there could be others).
If its value is STANDARD, then the elements are written
in the order given in FGDC-STD-001-1998 and extensions
are written after all standard elements. This is and
has been the default behavior. If the value is ASIS,
then elements are written in the order they appear in
the parse tree (as input in mp, as modified by Tkme).
Modified config.c to recognize the element "order"
which will be used when found under output:xml.
The effect of this change is to allow people to explicitly
request that mp and Tkme NOT rearrange the elements in the
order given in the FGDC standard. Since most profiles
have not put extensions after all standard elements,
using the standard order causes the extensions to be
put out of the order expected in the profile. This
change allows mp and Tkme to retain the input order.

whose contents will be incorporated into the HTML output as
if they had been specified as the header in the config file
itself. This allows you to maintain the HTML header separate
from the config file. A corresponding change was made for
footers; if the footer directive is not found under

its contents will be used as the HTML footer. (mp 2.7.12)

Process_Description:
Added direct support for the shoreline profile and the

keyword.h, keyword.c, syntax.c, ps8.c, and actions.c.
All programs got bumped a minor version number for this.
One of the side effects is a simplification so that all
elements defined in any of these profiles will be
recognized and their structure checked. However unless
you put "profile rs" or "profile sh" into the input
section of the config file, standard elements won't be
judged according to the rules specified in the profile.
So if you use elements from one of the profiles but
you don't tell mp you're using that profile, those
elements may be flagged as errors because mp thinks they
aren't supposed to be there. But that, in my opinion,
is better than having them come up as unrecognized
elements. (mp 2.8.0) (mq 2.6.0)

Modified local.c, creating a function add_extension() that

Modified decode_xml() in xml.c to call this function. The
net effect of this change is that unrecognized elements in
XML and SGML files will be tolerated and can be manipulated,
rather than ignored and possibly discarded altogether. The
practical effect, I hope, is that XML records produced by
any version of ArcCatalog can be edited safely using Tkme
and parsed with mp. Ideally, mp would be told exactly
where the extended elements go and how they should appear,
but with the emphasis on XML, it is possible to include
new tags in metadata without documenting them beyond
inclusion in a DTD, and the DTD step could conceivably be
skipped also, since well-formed XML suits most applications.

Modified keyword.c to add a function is_standard() which, given
an element's numerical key, tells whether the element is part
of the FGDC standard (through FGDC-STD-001-1998) or not.
Modified allow() in syntax.c so that only a warning is issued,
not an error, when a non-standard element appears where it is
not expected to be. This is a significant change from the
regulatory perspective. It means that mp will not call an
error the occurrence of an extension even if mp doesn't know
what the extension is or where it's supposed to go. The
chief benefit of this is that ESRI and other creators of
metadata tools can now invent and add elements to the
metadata they create without me having to play catch-up and
try to get accurate descriptions of what these extensions are
and where they should go.
This doesn't mean that downstream software will understand
the information in nonstandard elements, but if your metadata
record was generated by some software, mp won't tell you it's
wrong just because there's a nonstandard element in it that
mp doesn't know about ahead of time.

Process_Description:
Modified decode_xml() in xml.c to use expat, a freely-available XML
parser, rather than the original parser code. This will make the
input of XML documents more consistent, and fix the bug in which
the occurrence of a comment within the text of an XML element caused
the parser to discard the entire text (thanks to Hugh Phillips for
noticing this problem).
Backed off a prior change in which unrecognized extensions were
recognized and not discarded. Tkme wasn't written to distinguish
unknown compound extensions from scalar elements, so its behavior
became inconsistent when unknown extensions were permitted.

Process_Description:
Created a new extension file ESRI-ISO.ext within tools/ext. I built this
from the document type definition file found inside
http://www.esri.com/metadata/esri_iso01dtd.zip
Since I don't understand the ISO documents fully I cannot judge
how well the DTD corresponds to the ISO standard. I have used
the new ext file to parse metadata output by ArcCatalog 8.3,
and it appears to work, causing mp to understand and not discard
the ISO elements that ESRI has used. In principle this should
also have the effect of allowing people to edit ArcCatalog
metadata in place using Tkme without having to export the
record first. However caution is advised: make a backup copy
beforehand, and keep it until you are certain that both mp and
ArcCatalog can read the XML file successfully.
Process_Date: 20040129
Process_Step:
Process_Description:
Modified config.c and local.c to send to an internally-managed buffer
any error or warning messages generated while parsing the config file
or the extension files. The contents of these buffers can be
retrieved by calling config_errors() or ext_errors(). So the calling
program (typically mp or Tkme) decides if, when, and how those
messages are shown to the user. Modified mp.c to show those messages
after the banner is displayed. (mp 2.8.11)

Modified array rule_table in syntax.c to properly direct mp

Modified element_cmd() in mq.c to return the section number from
the standard document (1998 version) using the element command
like [element $name -number]. Note that section numbers are
highly problematic; they only refer to a specific version of the
standard document, some of the numbers have changed from the 1994
version to the 1998 version, one of the elements now has two
different section numbers (Online_Linkage occurs both within
Citation_Information and within Metadata_Extensions), and section
numbers do not occur at all in the biological or remote sensing
profiles. (mq 2.6.7)

Process_Description:
Modified parse_sgml() within xml.c so that parsing of SGML actually
begins with <metadata> rather than at the beginning of the file.
This is because expat chokes on the SGML DOCTYPE declaration, which
doesn't have the same form as an XML DOCTYPE. Modified decode_xml()
in xml.c to first parse a set of entity declarations if the record
begins with <metadata>. These entity declarations are not included
if the file begins with an XML declaration. The chief use of them
is to help parse SGML records previously created using mp. Thanks
to Sarah McGuire (NPS, Madison) for pointing this issue out.

Process_Step:
Process_Description:
Expat automatically converts ISO-8859-1 to UTF-8, so if you read
an XML file, the internal representation of characters will be
UTF-8. I still think it's good to store the plain text as
ISO-8859-1, so I now need to convert UTF-8 to ISO-8859-1 when
writing plain text.
Modified write_text_item() in text.c to convert UTF-8 characters
to ISO-8859-1. Created a separate module encoding.c to contain
the function unicode_of_utf8(), now global in scope. Removed the

case is to determine whether the text contains any zero bytes; if
it does, the text is assumed to be UTF-16. This is because I
occasionally see problems in which people using Microsoft Windows
have inadvertently converted their text files to UTF-16, which is
really a binary format for unicode characters. This will
certainly scramble any input files that are binary but are not
UTF-16, but those files aren't going to be readable metadata

Modified write_xml_item() in xml.c to minimize the number of
newlines printed when indentation of the XML output is requested
using a config file. Thanks to Drew Ignizio for suggesting this
revision. (mp 2.9.27) (xtme 2.7.23) (tkme 2.9.29) (mq 2.6.27)

Process_Description:
Modified decode_text() in text.c to examine the text checking
character encoding. Generates a warning if the encoding was not
specified but the characters are not UTF-8, generates an error if
the encoding was supposed to be UTF-8 and there are non-UTF-8
characters.
Modified write_contact() in html.c to remove a stray greater-than sign.

Modified check_scalar_children() in syntax.c to throw a bad-value
error when Transfer_Size contains anything other than a single
floating-point number. I had been writing units into this value,
like "52 kilobytes" in order to avoid specifying very small
fractional numbers of megabytes. But the standard does say "size
in megabytes" and "type: real", so I'm going to have to lose this
argument.
Also I cleaned up a few of the stray and unclosed <p> tags in the
FAQ metadata format output using CSS. HTML output needs a thorough
rewrite, but that will take more time. (mp 2.9.29)

Process_Description:
Modified check_date() in syntax.c to be more strict about date
values. Standard does specify that dates must be simple date
values and cannot, for example, specify a range like 2001-2006.
Previous versions of mp permitted this, but because some
downstream software throws an error on this type of value, we are
better off discouraging loose date values. (mp 2.9.30)

Modified keyword.h, keyword.c, ps8.c, and syntax.c to incorporate
new elements for the Lidar specification version 1.1. (mp 2.9.31)
Process_Date: 20150414
Process_Step:
Process_Description:
Modified keyword.h, keyword.c, ps8.c, and syntax.c to change the
Lidar extension elements Lidar_Density to
Lidar_Nominal_Pulse_Density and Lidar_Pulse_Spacing to
Lidar_Nominal_Pulse_Spacing. Added
Lidar_Aggregate_Nominal_Pulse_Spacing and
Lidar_Aggregate_Nominal_Pulse_Density per USGS tm11-B4 version
1.2. Thanks to Leslie Lansbery (USGS) for pointing this out.

Modified actions.c to delete duplicate entries for
WDetailed_Description and WOverview_Description in the remote
sensing profile. Their duplication was causing the XML generator
to duplicate these elements in the XML when the remote sensing
profile was used. Thanks to Florence Wong for pointing this out.

Process_Description:
Created html5.c from html.c and used it instead of the older file.
This is a rewrite of the outline-style HTML so that it conforms to
HTML version 5, and uses CSS more appropriately. Each element name
is contained within a <span> tag with the class element-name and an
additional class name matching the XML tag for the element. Each
element value is contained within a <div> (or <span> if the content
is short) with a class element-value and an additional attribute
matching the XML tag of the element. A <div> with class "child"
controls the indentation. The default value for blank lines is an
empty div with the class "blank". Conservative default values are
included for these CSS classes.
Modified element_end() in xml.c to strip leading space from blank
lines; this was causing mp to think that a line containing spaces
was not actually blank, now it considers that line to be blank.

Process_Description:
Modified syntax.c to flag as an error any extraneous characters
following real-number values such as bounding coordinates. This
catches situations in which a bounding coordinate is followed by a
letter like W, E, N, or S to indicate the direction.
Modified xml.c to report as an unrecognized-element error any XML
tags that were not recognized. Originally the filtering of
unrecognized XML tags was helpful as a way to remove
software-specific tags such as those used in ArcCatalog. VeeAnn
Cross helpfully pointed out that when a standard element's tag was
misspelled, mp was ignoring the element and its contents and
labeling the event an error but not counting it among the errors
in the summary report, potentially misleading users as to the
seriousness of the problem.
