Scope & Objectives

This working group focuses on best practices in support of authorities that want to share their metadata as linked data.  In this charter, the group will explore and make recommendations for change management of authoritative data.  We will define the common types of changes, determine the format for conveying changes to downstream consumers, and specify tooling options for publishing changes that allow for cached data to be synced and updated.  This work is specifically looking to provide recommendations that allow for the creation of a common toolset that works across authorities supported by different institutions.

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.

Deliverables & Timeframe

Anticipated deliverables will include:

  • Documentation on common types of changes that happen in authoritative data

  • Specification for expressing changes that have occurred in authoritative data
  • Recommendations for tooling to create and consume changes to authoritative data

The group will begin meeting in late spring 2021 (approximately mid April or early May).  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.
