Specifications

• The most important specification developed in this project is JSKOS data format to encode KOS data based in JSON and JSON-LD.

• The JSKOS-API to uniformly access KOS data has not been formally specified yet. See jskos-server as reference implementation.

• ELMA is a small subset of JSKOS-API.

Data

We collect and (re)publish data related to concordances and knowledge organization systems.

• Basisiklassifikation in RDF (Turtle) and JSKOS (ndjson)

• Concordances

• We daily harvest and convert authority file mappings from Wikidata.

• BARTOC database dumps

• List of common licenses

• Classification of Knowledge Organization Systems

See also jskos-data repository for a collection of knowledge organization systems encoded in JSKOS
