Vocabularies are organized knowledge structures. There are different types of vocabularies like authority files, classification systems, concept maps, controlled lists, ontologies, taxonomies, glossaries, subject headings etc. Their purpose is to facilitate the retrieval of content in data sets. In addition the VEST Registry Vocabularies contains currently 113 vocabularies. You can browse the vocabularies by type and subject domain.
Within the AIMS umbrella a number of different initiatives related to vocabularies are ongoing.
