Uniform access to knowledge organization systems and concordances from diverse sources is established with:
- a data format that all related information as converted to (JSKOS format)
- a set of web services that provide JSKOS format (JSKOS API, not fully specified yet)
- a set of Node libraries to access data sources in JSKOS format (see software)
Cocoda web application makes use of these unification via registries. A registry is an individual source of data, for instance the concordance registry or another public web service (see Cocoda manual).
