Does the "Digital Audio-Visual Preservation Prototyping Project" have worked
on MPEG-7 metadatas ?

MPEG-7 claim to be compatible with Dublin Core, SMPTE Metadata Dictionary
and others.

MPEG-7 addresses many different applications in many different environments,
which means that it needs to provide a flexible and extensible framework for
describing audiovisual data. Therefore, MPEG-7 does not define a monolithic
system for content description but rather a set of methods and tools for the
different viewpoints of the description of audiovisual content. Having this
in mind, MPEG-7 is designed to take into account all the viewpoints under
consideration by other leading standards such as, among others, TV Anytime,
Dublin Core, SMPTE Metadata Dictionary, and EBU P/Meta. These
standardisation activities are focused to more specific applications or
application domains, whilst MPEG-7 has been developed as generic as
possible. MPEG-7 uses also XML as the language of choice for the textual
representation of content description, as XML Schema has been the base for
the DDL (Description Definition Language) that is used for the syntactic
definition of MPEG-7 Description Tools and for allowing extensibility of
Description Tools (either new MPEG-7 ones or application specific).
Considering the popularity of XML, usage of it will facilitate
interoperability with other metadata standards in the future.
