Video Access Working Group

Phase I Deliverables:

In Phase one, this group will:

1. Implement Dublin Core as a descriptive metadata standard for digital video through the following activities:

º Develop and publish for review and revision a draft "best practices" recommendations for Dublin Core descriptive metadata for digital video, to the library, digital video and other Internet communities.

º Publish a draft Dublin Core XML and XML/RDF DTD as well as an HTML meta tag format for review and revision.

Publish a final Dublin Core "best practices" recommendation together with an XML DTD, XML/RDF DTD and HTML meta tag set. This final report will include a discussion of convergence and interoperability issues with other widely adopted standards, including:

  º OCLC CORC

º USMARC (particularly the AMIA implementation)

º CIMI best practices for Dublin Core

º ROADS

º IMS Meta Data Standard

º EAD

º MPEG7

2. Develop administrative and structural metadata for digital video, primarily to adequately describe the creation, distribution, access and display of digital video assets.

º Administrative and structural metadata will be used to identify:

  º the encoding and playback environments to technically identify and categorize video assets, to enable digital reconstruction of the video in the future, as technologies change.

º Composite objects and the atomic objects that comprise them.

º provenance and ownership of assets

º rights and access

º basic file management of video assets.

º Investigate convergence, reuse and interoperability with emerging standards and best practices, including:

  º CEDARS

º MOA II

º A-CORE

º Library of Congress structural and administrative metadata

3. This administrative and structural metadata will be combined with the enhanced Dublin Core descriptive metadata to create a complete digital video metadata standard--our primary deliverable--to be disseminated in the following manner:

  º We will publish a draft video metadata record (including XML and XML/RDF DTDs) for comment and review. I think we should strongly consider submission as an IETF draft standard.

º The metadata architecture will be defined as a metadata model as well as DTD and possibly SOX.

4. We will evaluate congruence with relevant metadata DTDs and information models, including:

  º OAIS--Open Archival Information System draft standard

º MPEG7

º MOA-II structural and administrative metadata DTD

º CEDARS metadata for digital preservation

º Dublin Core Data Model

5. The metadata architecture and record format will be widely disseminated to the digital video community:

  º We will register the data elements and value domains for our metadata record in an ISO/IEC 11179 compliant metadata registry, which will be published and promoted to the digital video, Internet, library and archives communities. An international registry will allow others to reuse some or all of the data elements we develop for their own metadata purposes, as well as documenting our decisions for those that follow us and have to manage the video assets we created.

º We will develop a database which can report as XML, XML/RDF and fielded Dublin Core (much like OCLC CORC) in Oracle, Access and MySQL. The database layouts will be published on the ViDe web site and available for download and use.

º We will open a "proof-ofo-concept" video access portal to demonstrate model and record efficacy for every video type.

º We will post a web form for record creation on a portal site to create a portal of distributed video resources. Each form will be downloadable to the creator as a fielded flat file and/or other record format for reloading at the creator's home site.

º We will actively develop and participate in a video data management workshop sponsored by ViDe and possibly co-sponsored by SURA, tentatively scheduled for fall, 2000.

The intent is for this workshop to be a training workshop focusing on the implementation of asset management, so we will provide training on video metadata, but we can also take advantage of the opportunity to share At a minimum we should have best practices Dublin Core and a draft "complete record" for the workshop.
