Scope & Objectives

The Samvera Metadata Interest Group (SMIG) is interested in working together on base metadata recommendations for the Samvera Community. The scope of this group concentrates primarily on metadata as it relates to Samvera projects such as Hyrax, Avalon, Hyku, and migration to Fedora 4. Types of metadata for which the group has or intends to create recommendations include technical, structural, descriptive, and rights metadata.

The larger goals of the Metadata Interest Group are to:

  • Identify models that may help Samvera newcomers
  • Further interoperability among Samvera projects
  • Provide support for the community and a place to ask metadata questions in Samvera
  • Provide ways to share metadata work (in progress or complete)
  • Collect documentation in order to more broadly facilitate shared modeling
  • Develop and charge working groups for Samvera community metadata activities

This interest group is not creating a new standard or implying any metadata constraints for Samvera projects.

Scope & Objectives and meeting frequency will be reviewed annually (around the time of Samvera Connect).

Sunset milestone: No meeting occurs for 6 months (at that point there will clearly be no interest in this interest group)
