Metadata in the Middle

To participate in centralized data search and access, Illinois Data Bank (the research data repository for the University of Illinois at Urbana-Champaign) contributes and maintains records for datasets in the DataCite Metadata Store, using the EZID API through Purdue University. The organizational and technical hand-offs through the various layers can be complex to navigate.nbsp;nbsp;nbsp;On the way from research data producers to consumers, Illinois Data Bank metadata is formatted, stored, subsetted, reformatted, and passed through several organizations.nbsp;University Library = EZID at Purdue = DataCite = International DOI Foundationnbsp;If a researcher needs to correct metadata or adjust publication delay, or a curator needs to suppress a dataset while reviewing concerns, Illinois Data Bank propagates adjustments along the chain. Supporting researcher self-deposit, along with a slate of curator controls, exploits the breadth of the API and requires an understanding of the connections among components. The goal of this poster will be to present these intricacies, along with some of our technical strategies for using the EZID API, in way that implements features of the Illinois Data Bank
