Editor's Notes
- Fragment media assets (since a consumer may be interested in only a part of a larger asset) Annotate those fragments (so that media retrieval can be at the fragment level) With Linked Data concepts (so programs can access metadata about any concept in an annotation and have a shared understanding of the semantics of the annotation) And use the Links in Linked Data to derive Links between Annotated Media.
- Space for Editor Tool: automated annotation can be inaccurate, process allows for editor checking and correcting annotations, use of named graphs/LinkedTV Ontology to maintain provenance information between automated and curated annotations in the media metadata
