Why use RDF in SMPTE ?
  - Issues
    
      - Harmonization and reuse of existing metadata formats/ontologies
        (SMPTE, EBU, MPEG-7, ...)
- Integration of SMPTE-specific vocabulary/ontologies
 
- RDF designed for that !
    
      - Vocabulary merging/multiple vocabularies was initial goal
- OWL allows concept mapping
 
- Tie into Semantic Web
    
      - Wide commercial and open-source support
- Enables innovative software development
