ISOcat: a Data Category RegistryThe reference implementation of ISO 12620:2009Terminology and other content and language resources — Specification of data categories and management of a Data Category Registry for language resourcesA data categoryis the result of the specification of a given data fieldan elementary descriptor in a linguistic structure or an annotation scheme

The role of data categories in CMDICMD components, elements and items can have links to conceptsThese links should be resolvableto a concept descriptionThis concept description gives explicitsemanticsElements and components can use different terminology but still have common semanticsISOcat provides resolvable links to the semantic description of data categories (DCs)CMD items: simple DCsCMD elements: complex DCsCMD components: container DCs (upcoming)

Status of the metadata profileInitial set of data categories has been created (to never disappear)Any additional data categories in the pipeline?Your own components might need your own DCsTranslations for many EU languages have been addedMostly green checksDeterioration due to new but incomplete translationsISO StandardizationTDG ballot is ending this weekImplementation of standardization process is ongoingThe addition of container DCs to be linked to CMD components is planned

Can you trust the DCR?Each, also when not standardized, data category has a Persistent IDentifier(PID)The Registration Authority of ISO 12620 is obliged to keep these PIDs resolvableThe DCR is a (core) component of many ISO TC 37 standards (TBX, TMF, LMF, LAF, …)The DCR is also a (core) registry in the CLARIN infrastructureISOcat is in beta, i.e., still actively being developed and not yet feature complete, however, core functionality is stable for everyday usage and being backed up every dayWe welcome any feedback! Contact us: isocat@mpi.nl

Can you trust a data category?Some TDGs are actively cleaning up their legacy:Metadata, Morphosyntax and TerminologyAlso at least 2 new TDGs are being establishedTranslation and Sign languageOthers are still asleep but will hopefully wakeup after the ending of the TDG ballotthe DCR development team might interact with them as closely as we do with the current active TDGs to speed them upThis means DCs are a bit in fluxGet in touch with the (private) owners (mediated mail is coming soon)Once standardized changes need to go through the standardization process, but old versions will always be available

Can you trust a private data category?There are no standardized DCs in the registry yetISO standardization of a DC is an optional stepStandardized DCs have extra safe guards, but might be slow in adapting to changes in the environmentISOcat uses a grass roots approachWork together in (adhoc)groupsInteract with owners of DCs (email, forum)Become members of TDGsThere might be some versioning policy for privately owned public DCsFreeze the English definition, i.e., a change of the semantics requires a new version (and the old version remains available)
