9. Using data categories
Each data category has a Persistent Identifier (PID):
This PID can be embedded in the schemata of linguistic resources:
<rng:element name=“gender” dcr:datcat=“…/DC-1297”>
The full data category specification can be downloaded from ISOcat in the Data Category Interchange Format (DCIF)
