Use Case: Audiovisual archive as a Cultural Heritage Institution
use case related to issue 6067
The collections of cultural heritage institutions (libraries, museums, archives, etc.) are increasingly made available on the Web. For large parts of these collections comprehensive, professionally created documentation is available, however, often using domain specific or even proprietary metadata models. This hinders accessing and linking these collections.
From the point of view of the media annotation WG, the use case of audiovisual content from cultural heritage collections is a broad one and contains the following technical challenges:
- interoperability: how can metadata from different collections be exchanged/mapped/merged?
- search: how to enable search across collections, e.g. all content related to a person/location/event? should the description scheme define a set of properties to make explicit relationships between the metadata elements describing one content to allow a precise description of the content (and not enforce it).
- deployment: provide metadata together with content in an interoperable way, but keep links to more detailed annotation in specific formats (e.g. low-level descriptors of audiovisual content, rights)
- fragment annotation: annotation in cultural heritage institutions goes far beyond simple tagging, many annotation refer to media fragments (e.g. story in a news broadcast, region in an image, etc.), thus there is a strong link to the Media Fragments WG
- controlled vocabulary: for this use case various types of controlled vocabulary (simple lists of values, thesauri, ontologies) must be supported, the use of different controlled vocabularies in the different collections causes another interoperability problem
- Cataloging Cultural Objects (CCO) portal contains a list of vocabularies and thesauri together with metadata schemas for describing cultural heritage objects. I'm not sure however that the current format allows to represent complex relationships in your annotations as you would like to put in the requirement 6083.
- VideoActive project: portal for content from European TV archives, maintains also a list of Web sites for accessing broadcast collections
- Europeana, portal of the European Digital Library, will in future also include audiovisual content from archives. The EC working group on DL interoperability has both interoperabilty with the Semantic Web as well as intra-object documentation (i.e. annotation on fragment level) on its list of future goals (cf. )
- First Workshop on Semantic Interoperability in the European Digital Library, the proceedings contain some papers dealing with multimedia content from cultural heritage collections
- ramm.x Proposal for light-weight RDFa based deployment of multimedia metadata on the Web
- Annotation format from MultimediaN e-culture project: it is generic enough to be applied to Multimedia documents, Demo of their search interface in CH collections
