ISO TC 37 Terminology and Other Language and Content Resources

ISOcat is an implementation of the ISO 12620:2009 standard, and is used to validate and check the consistency of this standard. One of the main changes to the previous draft of the standard is the revision of the DCR data model. This revised data model is now specified as an UML class diagram [ PDF ]:

 

● Overview [ SVG | EMF | JPEG ]

● Part I: administrative information [ SVG | EMF | JPEG ]

● Part II: descriptive information [ SVG | EMF | JPEG ]

● Part III: linguistic information [ SVG | EMF | JPEG ]

 

(Firefox supports the SVG vector format, and Internet Explorer the EMF vector format)

 

Together with the data model the Data Category Interchange Format (DCIF) also has been revised. And a small XML vocabulary to embed data category Persistent IDentifiers (PID) has been added to the standard. The latest version of these schemata are available here:

 

● DCIF schema in compact or XML Relax NG syntax;

● DC Reference schema in compact or XML Relax NG syntax.
