AbstractPaper presented at the ETD2012 Conference, Lima, Peru, September 12-14, 2012; Linked Data presents new opportunities to expand services surrounding theses and dissertations. By creating open datasets, ETD systems can be built to interoperate with other institutional data as well as with outside metadata sources. However, much foundational work must be done before these advantages can be fully realized. This paper details work at Oregon State University to create a Linked Dataset covering the University's theses and dissertations. Using data from existing MARC and Qualified Dublin Core records, we have established a process and model for crosswalking data from existing records into a variety of Semantic Web vocabularies. Our approach is to create basic services on a dedicated thesis and dissertation interface, incrementally extending those available through our institutional repository. We describe services implemented, those in progress and plans for continued work. We also address the limitations of our existing metadata and resulting challenges in crosswalking and interoperability. While Linked Data has great promise, implementation must target specific services that can be implemented today. We plan continued work to improve our data models and to utilize new data from other linked data sources as they emerge.
