Incites into Citation Linking using the OAI-PMH

About

There are some 300 repositories of research material (Source: IAR), most of which have an OAI-PMH interface, but no current Institutional Repositories export reference data - nor do they provide their users with citation impact metrics. We propose a model for extending IR's to be citation aware and to expose that data to citation indices using the OAI-PMH and OpenURL. We present some techniques for the export of citation data using the OAI-PMH in Citebase Search.

As part of a proposed Open Access Citation Information study we have developed a proposal for the integration of reference parsing and linking into the author- deposit process. This highly-distributed approach to citation linking utilises the OAI-PMH to transfer structured citation data between IRs and citation indexing services.

OpenURL - a standard for contextual linking using bibliographic data - is now a NISO standard. As well as it's linking role, OpenURL is a useful standard for the transfer of bibliographic data for the purposes of citation indexing. The developing DCMI guidelines for encoding citation metadata makes use of OpenURL context objects in XML. A more lightweight approach is implemented by Citebase Search for transferring bibliographic data using OpenURLs by encoding the metadata as URIs (OpenURL 'KEV' format) and including these in repeated simple Dublin Core relation elements.

The widespread adoption of OpenURL for contextual linking and the transfer of citation links will lower the barriers to citation indices as well as enabling novel new interactions between services (e.g. through the embedding of citation analysis services into IRs). Emerging technologies using the OAI-PMH and OpenURL will allow seemless linking across subscription-based and open access services, creating an integrated, citation-linked environment for researchers..
