ZORA is operated with the open source software Eprints. Eprints was developed at the University of Southhampton and is constantly being developed further. Eprints can be used to set up a repository. The software is compatible with the Open Archives Initiative Protocol for Metadata Harvesting OAI-PMH.
The Open Archives Initiative was created in the wake of a meeting in Santa Fe in October 1999 and is a central hub for technical and conceptual aspects of Open Access. Among other things, it is developing standards for interoperability that will enable scientific content to be disseminated efficiently.
