Service Provider staff that want to offer local catalogue users the opportunity to run their search queries against CDC, to provide them with additional results.
Data aggregators (such as OpenAIRE, B2Find, GoTriple) can easily harvest the entire contents of the data catalogue. Record identifiers are unified with those used in the User Interface.
To describe the use of the CDC OAI-PMH endpoint and provide a link to CDC SearchAPI documentation.
Use the standard OAI-PMH verbs to query the endpoint. For example, to list all the record identifiers and return the results in DDI 2.5 XML format, use ?verb=ListIdentifiers&metadataPrefix=oai_ddi25
The CDC Search API documentation is part of the CESSDA REST API collection. It is based on the OpenAPI standard, and as such it is possible to run test queries from within the page.
