Abstract. Ontologies are gaining increased importance in the area of multimedia retrieval or management as they try to overcome the commonly known drawbacks of existing multimedia metadata standards for the descriptions of the semantics of multimedia content. In order to build and use ontologies, user have to receive appropriate support. This paper presents the SALERO Semantic Workbench which offers a set of services to engineer and manage ontologies throughout their life cycle, i.e., from their (semi-) automatic creation through its storage and use in annotation and search. 1
