OAI-PMH Extension for CKAN

OAI-PMH API for B2FIND CKAN. This extends b2find CKAN to produce OAI-PMH metadata in DataCite format. Ckanext-oaipmh-server is based on https://github.com/kata-csc/ckanext-oaipmh

• GetRecord: fetches a single dataset.
• Identify: Displays information about this OAI-PMH server.
• ListIdentifiers: fetches individual datasets’ identifiers.
