7.
A data category is an elementary descriptor in a linguistic structure or an annotation scheme.

8.
Specification consists of 3 main parts:

9.
Administrative part

10.
Administration and identification

11.
Descriptive part

12.
Documentation in various working languages

13.
Linguistic part

14.
Conceptual domain(s for various object languages)</li></ul>TEI Lexical workshop - Würzburg, Germany<br />

12 October 2011<br />5<br />Data category example<br /><ul><li>Data category: /grammatical gender/

16.
Administrative part:

17.
Identifier: grammaticalGender

18.
PID: http://www.isocat.org/datcat/DC-1297

19.
Descriptive part:

20.
English definition: Category based on (depending on languages) the natural distinction between sex and formal criteria.

21.
French definition: Catégorie fondée (selon la langue) sur la distinction naturelle entre les sexes ou d'autres critères formels.

22.
Linguistic part:

23.
Morposyntax conceptual domain: /male/, /feminine/, /neuter/

French conceptual domain: /male/, /feminine/</li></ul>TEI Lexical workshop - Würzburg, Germany<br />

12 October 2011<br />6<br />What is a Data Category Registry?<br />www.isocat.org<br /><ul><li>A (coherent) set of Data Categories, in our case for linguistic resources

26.
A system to manage this set:

27.
Create and edit Data Categories

28.
Share Data Categories, e.g., resolve PID references

29.
Standardize Data Categories

30.
Grass roots approach</li></ul>TEI Lexical workshop - Würzburg, Germany<br />

Data Category identifiers are ambiguous<br />…<br /><LexicalEntry><br /> <feat att=“partOfSpeech” val=“commonNoun”/><br /> …<br />ISOcat contains two exact matches for “commonNoun” and one close match:<br />12 October 2011<br />8<br />TEI Lexical workshop - Würzburg, Germany<br />

33.
Why are identifiers ambiguous?<br />Several thematic domains can use the same name for a (slightly) different Data Category<br />This was already true in the predecessor of ISOcat SYNTAX (legacy)<br />There maybe multiple versions of the same Data Category<br />Due to semantic drift or rot the name can not just point to the latest version<br />Users can also create Data Categories with the same name<br />In the future even copy a Data Category to extends its conceptual domain<br /><ul><li>Identifier should have been renamed, e.g., to mnemonic</li></ul>12 October 2011<br />9<br />TEI Lexical workshop - Würzburg, Germany<br />

TEI and ISOcat Data Category PIDs<br />Is TEI open to attributes from foreign namespaces?<br /><ul><li>dcr:* attributes can already be used</li></ul>Or can the dcr:* attributes be part of the global attribute list?<br /><ul><li>It would enable to annotate any TEI element, incl. Dictionary elements, with a Data Category reference

38.
The DCR data model now also includes container Data Categories and can thus also cover inner nodes

39.
Could also (partially?) be done by <equiv/> statements in the ODD files

40.
Scripts to do this (semi-)automatically have already been created</li></ul>Or can at least the TEI/ISO feature structure part accept dcr:* attributes?<br /><ul><li>Add a DCR specific attribute list?

41.
Would make the ISO TC 37 standards consistent ISO 24610-1, ISO 24613:2008 and ISO 12620:2009</li></ul> Could also be another TEI attribute that expresses equivalence with an external (URI) specification (like <equiv/> in ODD) and which isn’t as much bound to ISOcatas the dcr:* attributes imply<br />12 October 2011<br />13<br />TEI Lexical workshop - Würzburg, Germany<br />
