## Subject vocabularies

Subject vocabularies are a tool that can assist in sharing and finding Open Educational Resources. Subject vocabularies are cross-institutional, often hierarchical lists with a taxonomy structure of terms defined within the subject area and used to describe coherent subject terms within a discipline or course based on competences or subject content. Subject vocabularies also ensure that the time spend on metadating Open Educational Resources is reduced and improve the quality of the metadata. The subject vocabularies also make it possible to identify which Open Educational Resources are needed.
