configFileThis resource identifies the configuration file used for specifying input options and local extensions. The default value for this resource is .mprc, so xtme will look in the current directory for a file with that name.
helpFileThis resource identifies the file containing text intended to assist the user in filling in element values, respectively. The default value for this resource is xtme.hlp, so xtme will look in the current directory for a file with that name.
keyboardFocusPolicyBy default, it matters where the pointer is when you press keys. If you like pointer focus in your window manager, you are probably comfortable moving the mouse around a lot while typing. But if, like me, you prefer click-to-type windows, then you will want to change this value to Explicit. Letter case doesn't matter. Actions for event translations The following actions are available for use in translation tables.
save Write the current file to disk save-as Save the current file under a different name quit Exit the editor without saving ok-save Accept the name given in the save-as dialog cancel-save Cancel the save-as dialog cut Remove the current node, making it the X selection copy Copy the current node, making it the X selection paste Paste metadata from this or another file clear Remove scalar children in the current subtree duplicate Create a copy of the current element help Display guide information for the current element dismiss Dismiss the guide information window hide Conceal elements below the current node show Reveal elements below the current node collapse Conceal all elements at a given level expand Reveal all elements at a given level list-home Move to the root node of the metadata list-up Move up one element in the list list-down Move down one element in the list list-pageup Move up one screen-full in the list list-pagedown Move down one screen-full in the listSome of these actions are the same as menu items, while others are not. There are no menu items that invoke the actions list-home, list-up, list-down, list-pageup, and list-pagedown. The list- actions are accomplished using the mouse in the scrollbar of the list window. 3. Input file format Since the FGDC Content Standards for Digital Geospatial Metadata, as the name implies, specifies only the contents of metadata files and not their encoding, it is necessary to choose or devise a specification for metadata encoding in order to create formal metadata. The encoding format interpreted and produced by this editor is the same as that used by mp. Interested users are referred to the documentation for mp for details on this file format. 4. Configuration file format The configuration file should be laid out exactly as for mp. 5. Local extensions Local extensions, element names not found in the FGDC standard and the relationships among them, are described in a text file laid out exactly as for mp. 6. Help file format A help file is provided with the editor. It contains brief descriptions of the standard elements, with the syntactical structure of compound elements described using the production rules of the standard. Additional elements can be added to this file. To add another element, place its name at the beginning of a line. The text describing the element should be placed on lines following the element name but in each of these lines the first character must be a space or tab. Elements can be added in any order. 7. Output file format The metadata are output using the same encoding format as input, but on output the indentation is standardized at two spaces per level in the hierarchy. 8. Operation The editor can be invoked with no arguments. In that case, the metadata will be saved as "Untitled" unless the name is changed using the Save As option in the File menu. If a file name is given on the command line, that file will be opened and its contents will be interpreted as metadata. If the file does not exist or is empty, a Metadata node will be created to which the user may add appropriate elements. The display consists of three parts: a menu bar at the top, a scrolling list widget containing the structural elements of the current metadata, and a text widget containing the contents of the currently selected element. To add an element to the metadata, select the parent element in the list widget, then choose the appropriate component from the Add menu. Note that the Add menu changes to reflect the components permitted under each element. When a scalar element (that is, one not composed of other elements) is selected, the Add menu will urge the user to enter the text in the text widget. The insertion caret will then be visible and text can be entered. Note that text can be inserted using the standard X selection (cut-and-paste) function. To delete an element of the metadata, select it in the list widget, and choose Cut from the Edit menu. Note that this removes the entire subtree (that is, the element, its components, and their components). The Cut option in the Edit menu makes the subtree available through the X selection mechanism, and the subtree can be pasted into another application. At this writing, the paste operation will convert the subtree to indented text. The Copy option of the Edit menu also makes the current subtree available to the X selection mechanism, but does not remove the subtree from the current tree. The Clear option of the Edit menu removes the scalar data from the current element, its components, and their components. This allows the user to retain the structure of a subtree but replace the information it contains. The Paste option of the Edit menu causes xtme to attempt to insert the subtree most recently cut or copied. The subtree is inserted as a child of the current element if that is permitted by the standard. If the first node of the subtree is not a child of the current element, xtme looks up the tree towards the root node for an element into which the subtree can be inserted. If there is no such element, the subtree is not inserted. To insert a section of metadata from another file or application, select it in the other application and invoke the paste action (by default, pressing the middle mouse button in the list window). The data are expected to be ASCII, indented using the same rules as for mp and xtme, so you can select a section of indented text using a text editor or use Cut or Copy from xtme. ------------------------------------------------------------ I have tried to make the paste menu item operate the same way as the paste action, but I have been unable to make it work without crashing. The problem appears to lie with the time value passed to XtGetSelectionValue; when the paste function is invoked through an action procedure, the time can be taken from the event that precipitated the action or from XtLastTimestampProcessed and the selection value is obtained quickly and correctly. But when the function is invoked through the menu item's callback procedure, the time obtained from XtLastTimestampProcessed, while apparently a legitimate time value, is somehow not correct, because the program freezes for a while, then dumps core. If you know a lot about Xt programming and are willing to assist with this problem, please send email to firstname.lastname@example.org. ------------------------------------------------------------ The Duplicate option of the Edit menu causes xtme to create an empty copy of the current element immediately following the current element, at the same level in the hierarchy. The Swap option of the Edit menu moves the element that is currently selected up in the list of components of its parent. This allows you to reorder the components of a compound element. The View menu allows the user to control the display of elements in the list widget. Options are as follows:
All levels Make the entire hierarchy visible. 1 level Conceal all elements below the first level. 2 levels Conceal all elements below the second level. 3 levels Conceal all elements below the third level. Hide Conceal all components of the current element. Show Reveal all components of the current element.Normally choosing "1 level" makes the components of Metadata visible but their components invisible. When an element's components are hidden, a plus sign is shown at its left side in the list widget. The Help menu has three options. Each causes text to be displayed in a popup window. To remove the popup window, choose its Dismiss button. The text widget is configured to wrap the text by default, but this can be changed by choosing the Wrap button. Version displays the version number and date of xtme. Element displays information specific to the element currently selected in the list widget. This information is updated every time you select a different element in the structure. Output displays the complete metadata record, with textual values in the indented hierarchical format. Note that the popup shows the metadata as it was when the Output option was selected and is not updated automatically. To display later changes, choose Output again from the Help menu. To exit the editor without saving changes to the metadata, choose Quit from the File menu. To save the metadata at any time, choose Save. To exit the program, saving the changes, choose Close. To save the metadata under a new name, choose Save As; a popup dialog permits entry of the new name. 9. Known bugs When pasting in a subtree from another application, xtme will crash if a line in a textual value in the pasted subtree begins with a recognized element and is indented relative to the text immediately following it.

Throughout the 1980s and early 1990s, the improving capability of desktop computers to carry out complex analyses has increased the popularity of geographic information systems (GIS). As they became familiar with GIS technology, people at all levels of government, in industry, and in academia have been calling for better access to publically-available geospatial information and more general use of standard terms of reference and of standard formats for the exchange of geospatial data and information. Answering this need is the goal of the National Spatial Data Infrastructure (NSDI), a government-wide coordination effort initiated at the Federal level through Executive Order 12906, which was signed by President Clinton in April of 1994. A key component of NSDI is the development of a National Geospatial Data Clearinghouse, a general source of information about geospatial data that are available to the public. With the Clearinghouse a user can determine whether geospatial data on a region of interest exist and are appropriate for solving the problem at hand. The Clearinghouse is a distributed network of internet sites providing metadata (information about geospatial data) to users in approximately the same way. Its success depends on the overall consistency of the metadata that are made available, because users are expected to evaluate metadata from numerous sources in order to determine which data meet their needs. To promote consistency in metadata, the Federal Geographic Data Committee (FGDC), an interagency council charged with coordinating the Federal implementation of NSDI, has produced the Content Standards for Digital Geospatial Metadata (CSDGM). That document provides standard terms describing elements common to most geospatial data, and encourages people who document geospatial data sets to use these terms. The Content Standards for Digital Geospatial Metadata (hereafter referred to simply as "the standard") describes not only the terms of reference but also specifies the relationships among those terms. The relationships, many of which are hierarchical, are complex and a formal syntax is provided to specify them. Because the syntax of the standard is complex and the number of descriptive elements is fairly large (335), creating metadata that conform to the standard is not an easy task. In addition to the problem of assembling the information needed to properly describe the subject data sets, data producers must arrange that information using the terms given in the standard and arrange the terms using the syntactical rules given in the standard. The resulting metadata are formally structured and use standard terms of reference, hence the term "formal metadata" in the title of this report. This software is designed to simplify the process of creating formal metadata conforming to the standard. It provides the element names, maintains the hierarchical structure, and ensures proper arrangement of elements.
input language esReplace es with id for Indonesian; en would be for English, but if the value is unrecognized or missing the software will use English element names. (xtme 2.5) (tkme 2.5)
+ Process_Step Process_DateIn this example, the plus sign indicates that this particular Process_Step element has some children that are currently hidden, and the new Process_Date element that we just added is only one of them. By forcing the hidden siblings to be exposed, the user can immediately see the context in which the new element has been added. (tkme 2.6.4)
<place> <placekt>Name of the thesaurus <placekey>term1</placekey> <placekey>term2</placekey> </placekt> </place>Note that here element placekt contains both the text of the thesaurus name and the placekey elements which are terms from that thesaurus. This is somewhat analogous to the situation in a text file where an element name appears at the beginning of a line in a data value. But in that situation it is mp's parser that has misinterpreted the data, not invalid structure per se. Consequently it can be repaired automatically. But in the case shown above the fault lies in the generator of the XML code, and it cannot reliably be repaired. (tkme 2.8.13) (xtme 2.6.6)
