Most image annotations make use of the DDL/XMLSchema-based approach of
MPEG-7, Dublin Core, VRA etc that predate Semantic Web technology. This
document addresses interoperability issues between these technologies and RDF
and OWL-based approaches.
Institutions and organizations with research and standardization
activities in the area of multimedia, professional (museums, libraries,
audiovisual archives, media production and broadcast industry, image and
video banks) and non-professional (end-users) multimedia annotators.
- Investigate potential approaches for image annotation strategies that
combine and/or integrate the SemWeb languages approach (RDF, OWL, SPARQL,
Rule Languages, …) with the DDL/XMLSchema-based approach of
MPEG-7, Dublin Core etc in an interoperable way.
- Develop best practice guidelines for image annotators that want to
export their annotations on the Semantic Web and/or import SemWeb data
into their image annotation tools.
This is a public (WORKING DRAFT) Working Group
Note produced by the Multimedia Annotation in
the Semantic Web Task Force of the W3C Semantic Web Best
Practices & Deployment Working Group, which is part of the W3C Semantic Web activity.
Discussion of this document is invited on the public mailing list public-swbp-wg@w3.org (public
archives). Public comments should include "comments: [MM]" at the start
of the Subject header.

TBD: Basic information on the image annotation standards
TBD An inside view of semantic and syntactic details of MPEG-7, Dublin
Core, VRA, ?.
TBD Separate description of syntactic interoperability issues between the
image annotation standards and OWL.

3.2 Syntactic interoperability between VRA and OWL
...
TBD Separate description of semantic interoperability issues between the
image annotation standards and OWL.

5. Tranforamtions and mappings between different image annotations
TBD Description of possible tranformation issues. Some connections with
definition of mappings and ontology alignment techniques should be also
provided.
6. Feasibility study
TBD Provide a feasibility report for the interoperability that clarifies
the levels of interoperability that could be achieved in each case.
7. Good practices for constructing interoperable image annotations
TBD Using the above feasibility study, the main ideas for constructing
interoperable image annotations using the above standards should be
described. Clear and easily understood suggestion for annotators and maybe
tool developers.
