BARTOC relaunch at Common Library Network GBV


The terminology registry BARTOC has been moved to the head office of common library network Gemeinsamer Bibliotheksverbund (GBV). BARTOC contains information about more than 5.000 knowledge organization systems such as thesauri, ontologies, and authority files. The content is curated by an international group of editors and it is published as open content in human-readable and machine-readable form. The migration includes a change of the name from "Basel Register of Thesauri, Ontologies & Classifications" to "Basic Register of Thesauri, Ontologies & Classifications". BARTOC was developed and hosted at University Library Basel by Andreas Ledl starting in 2013. Its new technical infrastructure is based on project coli-conc. With the relaunch BARTOC becomes a central element of authority based services such as uniform lookup in vocabularies and authority file mappings with the web application Cocoda.

The URL of BARTOC stays at and we made sure to keep all existing links and content. Feedback, corrections and hints on additional vocabularies are welcome by the BARTOC editors!
