Why formalizing DatCats?

Systematizing data category description:– Notion of Data Category Registry (DCR)

• I need a data category: is it there?– Query by name, definition etc.

Automatizing processes:– Format control of TMLs– Filters from one TML to GMT

Which model for DatCats?

Using XML:– Coherence with TMF principles– Using stylesheet to generate schemas and filters

Using RDF (Resource Description Framework)– Intended format for representing meta-data:

• Description of a DatCat is meta-data with regards TMF

RDF - a quick presentation

Simple and complex DatCats

Complex data categories– shall serve as field identifiers (not names) in databases

and can have content. The datatype for this content shall be declared for each data category and can commonly take the form of different categories of text, defined data types (such as dates), and specified data domains, e.g., picklists comprising standardized permissible instances.

» Example: /Part of Speech/

Simple data categories– shall serve as the content of complex data categories.

» Example: /Noun/, /Verb/, /Adjective/ etc.

Dealing with languages

Two types of languages

Working language• The language used at a given place in a document,

along the XML hierarchy

• Representation: xml:lang

Object language• The language about which you speak at a given place

in your terminological entry (e.g. describes the Language Section level)

• Representation: as a data category "language", with a narrow scope

Example — DXLT

<langSet lang='en’ xml:lang="fr"><descrip type="definition">Une valeur entre 0 et 1 utilisée...</descrip><tig>

<term xml:lang="en">alpha smoothing factor</term>

<termNote type="termType">fullForm</termNote></tig>

</langSet>

Example — GMT

<struct type="LS" xml:lang="fr"><feat type="language">en</feat><feat type="definition">Une valeur entre 0 et 1 utilisée...</feat><struct type="TL">

<feat type="term" xml:lang="en">alpha smoothing factor</feat>

<feat type="termType">fullForm</feat></struct>

</langSet>

Conclusion

– A general model for analysing and representing terminological data collection

– An underlying formalism expressed in XML,RDF

– Associated tools (Salt project)• DCSEditor,

• DCSBrowser,

• Automatic generation of XSLT filters and XML schemas from a given TML specification
