Here’s an excerpt from the press release:
OpenDOAR, as a SHERPA project, is pleased to announce the release of an API that lets developers use OpenDOAR data in their applications. It is a machine-to-machine interface that can run a wide variety of queries against the OpenDOAR Database and get back XML data. Developers can choose to receive just repository titles & URLs, all the available OpenDOAR data, or intermediate levels of detail. They can then incorporate the output into their own applications and ‘mash-ups’, or use it to control processes such as OAI-PMH harvesting. . . .
OpenDOAR is a continuing project hosted at the University of Nottingham under the SHERPA Partnership. OpenDOAR maintains and builds on a quality-assured list of the world’s Open Access Repositories. OpenDOAR acts as a bridge between repository administrators and the service providers who make use of information held in repositories to offer search and other services to researchers and scholars worldwide.
A key feature of OpenDOAR is that all of the repositories we list have been visited by project staff, tested and assessed by hand. We currently decline about a quarter of candidate sites as being broken, empty, out of scope, etc. This gives a far higher quality assurance to the listings we hold than results gathered by just automatic harvesting. OpenDOAR has now surveyed over 1,100 repositories, producing a classified Directory of over 800 freely available archives of academic information.
