Meeting notes

🎥 10'41": This was an open meeting with primary goals of reviewing proposed wording around the use of identity and metadata assertions in combination and preparing an initial draft of a metadata example.

Review metadata assertion PR #4: Recommend use of identity assertion to attest to metadata authorship

🎥 13'38": Reviewed metadata assertion PR #4: Recommend use of identity assertion to attest to metadata authorship.

Group agreed to wording. Will discuss in next full CAWG meeting.

Review metadata assertion PR #5: Add media identifiers appendix

🎥 15'58": Reviewed metadata assertion PR #5: Add media identifiers appendix.

Revised wording based on discussion.

Challenges (unresolved as of yet):

  • Lacking an easily linkable list of metadata namespaces.

  • Dublin Core has a fairly coarse set of contributor roles. Motion picture may need more nuance.

To research:

  • MovieLabs data format (may be too verbose — and only available as an XML syntax)

  • Library of Congress schemas

Updated the PR to add a rough draft example using EIDR and HAND identifiers.
