The OeAI Thesaurus is a series of controlled vocabulary collections created from the database structure of the OeAI. These themed thesauri with standardized concepts are used to improve the indexing and searchability of the OeAI digital collections. The thesaurus is multi-lingual and provides definitions and links to authority databases. It is managed via Vocabs, a collaborative vocabulary creation service maintained by the ACDH of the OeAW, which uses a SKOS-based data model.
