API definition

The deliverable consists of the interface definition of a web API that can be used to federate data from all the PaNOSC catalogues. This is the first tier of the PANOSC metadata search API that supports queries based on generic metadata terms included in, for example, OpenAIRE or DOIs. Consideration should be given to how this can be implemented at partner sites in their local metadata catalogues. An extension for rich domain specific metadata should be planned, but does not have to be fully defined at this point.
