Technical Metadata Working Group

Draft Scope & Objectives

***Work Completed***

The initial set of tasks defined for the Technical Metadata Working Group are complete. If additional deliverables and/or technical metadata issues need to be addressed, please contact the Samvera Metadata Interest Group.

This group is interested in working together on recommendations for extracting and representing technical metadata and is a subgroup of the Samvera Metadata Interest Group.

The initial goals of the group are:

Technical Metadata Application Profile
FITS recommendation, if using FITS, to use FITS output captured as a NonRdfSource repository object; see "Detailed Technical Metadata Captured as XML"
in Technical Metadata Application Profile
Recommended tools for technical metadata and paths for integration with Hydra projects; See "Tools" below.
