CGSpace is built on DSpace. It is interoperable with other repositories and supports content discovery and re-use through use of international Dublin Core Metadata standards as well as CGIAR-wide metadata standards.
The repository's metadata is exposed through both the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and a REST API interface — /oai and /rest, respectively. For more information see the DSpace documentation.
Please try to exercise restraint when using these resources. For example, it is a great help to us if your programmatic use of the server can respect our robots.txt, specify a user agent for its requests, and reuse its JSESSIONID cookie. Also note that we have a public test server at dspacetest.cgiar.org which is running a recent snapshot of the production CGSpace software and data — please use this if you're testing a new integration or harvesting process! Lastly, if you are using our data we would love to hear from you.
The CGSpace source code is managed on GitHub.
