4. An ISO TC 37/SC 3 standard

5. Replaces ISO 12620:1999, a hardcoded list of Data Categories, with a registry for (standardized) Data CategoriesTEI Lexical workshop - Würzburg, Germany

6. 12 October 20114What is a Data Category?The result of the specification of a given data field

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)TEI Lexical workshop - Würzburg, Germany

15. 12 October 20115Data category exampleData 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/

24. French conceptual domain: /male/, /feminine/TEI Lexical workshop - Würzburg, Germany

25. 12 October 20116What is a Data Category Registry?www.isocat.orgA (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 approachTEI Lexical workshop - Würzburg, Germany

31. ISOcat and LMF§4.4 ISO 12620 Data Category Registry (DCR)“The designers of an LMF conformant lexicon shall use data categories from the ISO 12620 Data Category Registry (DCR) located at www.isocat.org.”§ 5.4 LMF data category selection proceduresCreate a Data Category SelectionAdd Data Categories to ISOcat if neededMissing: how to refer to ISOcat Data Categories?12 October 20117TEI Lexical workshop - Würzburg, Germany

32. Data Category identifiers are ambiguous…<LexicalEntry> <feat att=“partOfSpeech” val=“commonNoun”/> …ISOcat contains two exact matches for “commonNoun” and one close match:12 October 20118TEI Lexical workshop - Würzburg, Germany

33. Why are identifiers ambiguous?Several thematic domains can use the same name for a (slightly) different Data CategoryThis was already true in the predecessor of ISOcat SYNTAX (legacy)There maybe multiple versions of the same Data CategoryDue to semantic drift or rot the name can not just point to the latest versionUsers can also create Data Categories with the same nameIn the future even copy a Data Category to extends its conceptual domainIdentifier should have been renamed, e.g., to mnemonic12 October 20119TEI Lexical workshop - Würzburg, Germany

34. ISOcat Data Category PIDs are uniqueEach ISOcat Data Category (version) has an unique PIDhttp://www.isocat.org/datcat/DC-1256/common noun/ by Gil FrancopouloISO 12620:2009 Annex A provides a small vocabulary to annotate an XML document with Data Category PID references:<featatt=“partOfSpeech”dcr:datcat=“http://www.isocat.org/datcat/DC-1345”val=“commonNoun”dcr:valueDatcat=“http://www.isocat.org/datcat/DC-1256”/>Preferably annotate the schema of the resource12 October 201110TEI Lexical workshop - Würzburg, Germany

37. TEI and ISOcat Data Category PIDsIs TEI open to attributes from foreign namespaces?dcr:* attributes can already be usedOr can the dcr:* attributes be part of the global attribute list?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 createdOr can at least the TEI/ISO feature structure part accept dcr:* attributes?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 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 imply12 October 201113TEI Lexical workshop - Würzburg, Germany
