This charter has ended and is not longer active.

Scope & Objectives

This group will explore best practices for authorities that want to share their metadata through a linked data search API.  This work is specifically looking to provide recommendations that allow for the creation of a common toolset that works across authorities supported by different agencies.  The major outcome of this working group will be descriptions of the best practices in an easy to follow document empowering authority providers to create APIs and other deliverables that are compatible with supporting the development of a shared toolset.  Additional documentation may be created providing authority consumers with a consistent pattern for writing tools and consuming authority metadata.

This group should be comprised of a balance of members from multiple authority providers, authority consumers, and tool developers.  Members need to be able to commit to the following deliverables and timeframe.


As the group process unfolded, it became clear that identifying use cases and user stories was necessary first step to insure the space was clearly defined.  We hope that follow-on charters will address some of the original objectives statement.

Deliverables & Timeframe

Anticipated deliverables will include:

  • Primary: Documentation of best practices for authority providers creation of linked data search APIs

  • Secondary: Documentation of patterns for writing tools and consuming authority metadata
  • Review by community of designs and solicitation of feedback

The group will begin meeting in late spring or early summer 2020 (approximately late May or early June).  The group will meet for 1 hour every other week and its sunset date will be approximately 4 months after the start date.  If more time is required, a new working group charter will be created.


As per the adjusted objectives statement, the following are the final set of deliverables for the first charter of the working group.
