The lack of standardization in the production, organization and dissemination of information in docu- Renato Rocha Souza is a researcher, professor and data scientist with more than twenty years of experience in in- formation science, applied mathematics and computer science working with: a) data science, machine learning and analytics; b) scientific programming, natural language processing; c) information management and retrieval; d) knowledge organization and representation; e) knowledge management; and, f) education and research.

The sheer availability of multimedia content has fostered the development of many distinct and, most of the time, independent metadata standards for its description. This study aims at presenting and comparing the existing standards of metadata, vocabularies and ontologies for multimedia annotation and also tries to offer a synthetic overview of its main strengths and weak- nesses, aiding efforts for semantic integration and enhancing the findability of available multimedia resources on the web. We also aim at un- veiling the characteristics that could, should and are perhaps not being highlighted in the characterization of multimedia resources.
