Group Co-Conveners:


Several institutions have LD4P projects that involve special collections and rare materials. This affinity group seeks to make use of the collective expertise across the member and cohort institutions to discuss needs and challenges particular to rare materials, and to coordinate the development of resources to support our work.

The Rare Materials Affinity Group will build upon the existing strong relationships among rare materials communities, and will liaise with associated communities as needed.

Projects this group may undertake include:

  • development of rare materials-specific profiles tailored to the descriptive needs of the collections we have selected for our projects

  • providing use cases and feedback to the Art and Rare Materials Ontology Joint Task Force

  • evaluation of data conversion from a rare materials perspective

  • comparison of the Library of Congress BIBFRAME rare materials profile with profiles created using the ARM extension

  • examination of work being done by the Library of Congress on a Providers File to reconcile blank node providers (in provision activities)
