A dynamic OAI publisher service in the DRIVER repository infrastructure

OAI-Publishers are software modules enabling harvesting of metadata records describing the digital resources of a Digital Repository. Typically, such modules are manually configured and implemented to export records contained into a local store according to a predefined number of metadata formats. Due to their static nature, these are not apt to the dynamic context of Repository Infrastructures, where a virtual store, made of a dynamic pool of distributed physical stores, may hosts records of unpredictable metadata formats. In this document, we describe the internal architecture of the OAI-Publisher Service built for the DRIVER Repository Infrastructure. The Service is capable of self- configuring its internals so as to adapt to the variable content of the virtual store. Finally, we shall describe some extensions for the creation of dynamic collections and formats.
