Metadata extensions for mp, cns, tkme, and xtme

Extensions are explicitly permitted by the FGDC metadata standard, and a structure is provided in the standard to describe the characteristics of non-standard elements that a metadata record might use. The files here describe extensions that may be useful to some metadata authors, and they also serve as examples depicting the flexibility of the CSDGM.

The following types of files are provided here:

Extension	Usually something.ext, this file describes the non-standard elements that can be used. The metadata processing programs (mp, cns, xtme, tkme) are made aware of the extension file by an extensions directive in the config file.
Tips	Optional file that gives short texts tkme will use to provide hints indicating whether an extended element is optional, repeatable, or some other helpful information.
Config	Example config file that could be used to make the metadata software aware of the extension.

Extension	Tips	Config	Description
ESRI-ISO.ext			ESRI's version of ISO metadata
ESRIprof80.ext			ESRI's extensions, introduced in ArcGIS 8.0; used primarily by ArcCatalog to keep the metadata in sync with the data.
NPS.ext			National Park Service metadata extensions
bio.ext	bio.tip		For reference only NBII extensions for biological data. These are now supported directly by mp, cns, xtme, and tkme.
cfg.ext		cfg.cfg	Extension allowing Tkme to edit the config file.
contact.ext	contact.tip		A single, simple extension to allow additional contact information within Point_of_Contact; the new element is Originator_Contact and its content is Contact_Information.
ext.ext		ext.cfg	Extension allowing Tkme to edit an extension description file.
geo-age.ext	geo-age.tip		For reference only Geologic age extensions. These are now supported directly by mp, cns, xtme, and tkme as part of the biological data profile.
hierarchy.ext	hierarchy.tip		Extensions for handling hierarchical metadata records.
parts.ext	parts.tip		Extensions for describing the internal structure of a data set
rs.ext		rs.cfg	For reference only Remote sensing extensions. These are now supported directly by mp, cns, xtme, and tkme.
smms.ext		smms-complete.cfg	Extensions for the export format of SMMS.
