n 2010 FAO and UNESCO-IOC/IODE decided to collaborate on customizing DSpace. The main reasons:

Both organizations support synergistic document repository communities with similar metadata standards and controlled vocabularies: the AGRIS (FAO) and Odin- OceanDocs (UNESCO-IOC) communities.
Both organizations were independently of each other working on a customization of DSpace. In 2004 the Hasselt University Library in Belgium produced for IODE a customized version of DSpace called OceanDocs and adapted it to the standards of the oceanographic community. FAO on the other hand customized in collaboration with the Indian Statistical Institute in 2007 DSpace as a tool for AGRIS centres using the AGRIS Application Profile (AP). In collaboration with Kasetsart University in Thailand, FAO also developed an AGROVOC thesaurus plug-in for DSpace 1.5.2 (source code available on Google Code).
It made sense to join efforts and integrate in a common repository software the best of both worlds. The customization is called AgriOcean DSpace (ODA), and integrates the previous developments of both agencies in a single customized version of DSpace.
