Vocabulary browsing in BARTOC


The vocabulary registry BARTOC contains metadata about several thousand library classifications, thesauri, ontologies and other controlled vocabularies to improve visibility and findability of knowledge organization systems. With the migration to coli-conc infrastructure, we also aim to improve direct access to vocabulary content. This includes information about public APIs to access vocabularies, for instance Skosmos, Skohub, JSKOS API, SPARQL, and other kinds of webservices.

Based on these APIs we started to implement searching and browsing in vocabularies as part of BARTOC user interface. See Library of Congress Genre/Form Terms, EuroVoc, Regensburger Verbundklassifikation (RVK), and DDC. The latter is only available in German because of the license.

Unification of vocabulary services in BARTOC will be presented at poster at Code4Lib 2021 conference. A small slideset is available via


Cocoda 1.4.7 adds support of more English vocabularies such as MeSH and LCSH
