Description: The MBLWHOI Library is partner in the NSF-funded EarthCube building block, GeoLink, whose goal is to push the boundaries of semantic technology in cross-repository discovery within the geosciences field. GeoLink has created ontology design patterns that link together: the MBLWHOI Library’s Woods Hole Open Access Server (WHOAS); data repositories, including Rolling Deck to Repository (R2R), Biological and Chemical Oceanography Data Management Office (BCO-DMO), Integrated Earth Data Applications (IEDA), Long-Term Ecological Research Network (LTER), DataONE and the International Ocean Discovery Program (IODP); the National Science Foundation (NSF) funded awards; and American Geophysical Union (AGU) conference presentations. ­

Methods: The Library created WHOAS, a DSpace repository, more than 10 years ago. As part of the GeoLink project we have been collaborating with @mire, a leader in open source DSpace development to develop modular code that can be integrated into other DSpace installations to improve LOD functionality.

Expected Outcomes: Our DSpace goals are to provide a built-in SPARQL endpoint for easy access to the data, implement editable authority concepts with URIs, and be able to integrate concepts from other authoritative sources using SPARQL queries. There is a second layer that takes dc-based DSpace triples and constructs triples based on GeoLink patterns which describes the data in a geoscience context. This provides flexibility and serves as a model for organizations contributing data to multiple LOD communities. This code is freely available to the 1700 registered DSpace repositories worldwide.

Evaluation Method: We will determine the effectiveness with which we can contribute to the GeoLink Knowledgebase.
