Ontologies have seen quite an enormous development and application in many domains within the last years, especially in the context of the next web generation, the Semantic Web. Besides the work of countless researchers across the world, industry starts developing ontologies to support their daily operative business. Currently, most ontologies exist in pure form without any additional information, e.g. authorship information, such as provided by Dublin Core for text documents. This burden makes it difficult for academia and industry e.g. to identify, find and apply - basically meaning to reuse - ontologies effectively and efficiently. Our contribution consists of a proposal for a metadata standard, so called Ontology Metadata Vocabulary OMV.
