The Metadata Standards Catalog (MSC) Working Group has produced a machine-actionable catalog of metadata standards submitted by all RDA WGs. The catalog system has an end-user input form and an API for submission from other software. Similarly it has a user interface for query/reporting and an API for software to query and retrieve suitable standards information. The MSC is a fundamental tool in any autonomic e-research fabric.


This work builds on the outputs of the Metadata Standards Directory Working Group: both the Metadata Standards Directory (MSD) itself and the set of attendant use cases.


Further details about the work are available on the MSCWG Wiki.


Metadata Principles and their Use

The RDA metadata groups have developed and endorsed a set of five principles for metadata that they believe the wider RDA should adopt and promote.


Current Activities

The Metadata Standards Catalog is available. Please do contribute by adding new standards, new versions of standards, and filling out any missing information.


You can inspect the source code by visiting the GitHub repository. Even though the main, initial development phase is over, the Catalog will continue to be maintained and developed.


Current Events

RDA Plenary 16 Costa Rica (Virtual), IG Metadata: Progressing the Metadata Element Set

Breakout 3: 2020-11-10, 17:00 – 18:30 UTC


Meeting objectives


MIG has proposed metadata ‘packages’ for the commonly required purposes; a ‘package’ consists of elements (attributes or data structures) the values of which relate to the unique identity of the dataset or record (instance). To assure machine processing a formal syntax and declared semantics are required, and the packages must exhibit referential and functional integrity as well as human readability. The objective of this meeting is to progress the element set by unpacking the individual elements through work with other groups.


Meeting agenda

  1. Welcome (5 min)

  2. Progress to date on Metadata Standards Catalog and the elements (10 min)

  3. Current work in groups including survey results (10 min)

  4. Unpacking one or more of the high priority elements by the attendees (40 min)

  5. Plenary for report back (10 min)

  6. Next steps (5 min)
