OCLC supports evolution of IIIF
The work includes integrating IIIF standards in OCLC products and launching a new linked data pilot project.
OCLC is a member of the IIIF (International Image Interoperability Framework) Consortium and has been integrating IIIF standards in OCLC products for the past three years.
In addition to using IIIF standards to enhance current OCLC products, OCLC Research is supporting the evolution of the standards by testing emerging IIIF specifications and features. These collaborative efforts are noted and appreciated by the IIIF community, including by community leaders such as Antoine Isaac (Europeana).
Most recently, OCLC Research has been evaluating the new IIIF Change Discovery API as a syndication and aggregation protocol. This experimental work has confirmed the benefits of standardization around the IIIF APIs. Our work included retrieving data via our experimental implementation of the API standard to build an aggregation of around 13 million image descriptions contained in OCLC’s CONTENTdm digital content system.
We created an index based on that aggregation and prototyped a “IIIF Explorer” user interface for discovery. This effort surfaced metadata analysis and synthesis challenges associated with combining resource descriptions created by a wide range of cataloging agencies with diverse practices and suggested potential remedies for improving descriptive and technical metadata for cultural heritage collections with shared, decentralized tools and workflows in the hands of the data providers and domain experts.
Based on findings from this research, OCLC has launched a linked data pilot project focused on managing cultural heritage materials, working with three CONTENTdm customers: the Huntington Library, Art Museum and Botanical Gardens, the University of Minnesota, and the Cleveland Public Library.More information on this pilot project will be announced soon.
