Presentation type: PresentationAbstract:
OCLC Research is participating in the IIIF Discovery Working Group's on-going effort to develop a "Change Discovery API". The Change Discovery API will provide the information needed to discover and subsequently make use of IIIF resources. To exercise the developing API, OCLC Research deployed an experimental "Change Discovery Service" in December 2018, which enabled API access to 13 million CONTENTdm IIIF resources and included a demonstration user interface to test the utility of indexes built from the API-accessible IIIF resource data. This experimental work has confirmed the benefits of standardization around the IIIF Change Discovery API. It has also highlighted the metadata analysis and synthesis challenges of working with heterogeneous IIIF resource descriptions in a large aggregation, while testing potential search-and-retrieval remedies. This discussion will summarize OCLC Research's development efforts and report our findings from this early experimental work.
