Munoz, TrevorAs part of the Workset Creation for Scholarly Analysis (WCSA) project led by the HathiTrust Research Center (HTRC), the Maryland Institute for Technology in the Humanities (MITH) developed prototypes for a set of services and interfaces that would allow scholarly research teams to pull metadata records from the HathiTrust APIs, correct and annotate these records using standardized vocabularies, gather corrections and annotations from other application instances, and export them in formats suitable for publication as linked data. MITH also proposed to produce a demonstration of an index service that would allow research groups to register their data publications in order to make them available to other groups through a discovery interface.en-USlinked dataHathiTrustmetadataannotationTechnical Report
