Does everyone know ESIP has an Ontology Repository?
ESIP members wanted a simple repository that would let users try out semantic technologies, understand their benefits, and explore possible applications that used semantic resources. The Community Ontology Repository (COR) is a deployment of the Marine Metadata Interoperability (MMI) project's Ontology Registry and Repository software, meant specifically for use by ESIP and the Earth Science community.
How do I try COR?
Using COR is simple, and it's there for the Earth science community to test. Go to the COR website, register (if you don't have an account), and click the “Add vocabulary” button.
