The OAI2LOD server: Exposing OAI-PMH metadata as linked data

Abstract

Many institutions grant access to their metadata repositories via the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). However, this protocol has two significant drawbacks: it does not make its resources accessible via dereferencable URIs, and it provides only restricted means of selective access to metadata. The OAI2LOD Server handles these shortcomings by republishing metadata originating from an OAI-PMH endpoint according to the principles of Linked Data. As the ongoing OAI-ORE specification process shows, these principles are gaining growing importance also in the digital libraries domain.
