Content from the DataCite Metadata Store via OAI-PMH.
This service is open to everyone and is meant to be accessed by OAI-PMH compliant harvesters or any application that issues OAI-PMH requests. The service base address is
http://oai.datacite.org/oai and the service identifier is available here.
In brief, OAI-PMH provides a set of services that enables exposure and harvesting of repository metadata. The protocol is comprised of six verbs that specify the service being invoked, they are:
Selective harvesting can be performed by the use of accompanying parameters. Available parameters are:
The verbs and parameters can be combined to issue requests to the service such as:
For more details on the protocol, its implementation, and uses please visit the OAI-PMH web site.
The DataCite OAI-PMH Data Provider is able to disseminate records in the following formats:
As a minimum requirement for OAI-PMH compliance, metadata must be made available in the OAI Dublin Core format. For more information please see the OAI-PMH web site.
This metadata format has been specifically established for the dissemination of DataCite records using OAI-PMH. In addition to the original DataCite metadata, this format contains several other elements describing the version of the metadata, whether it is of reference quality, and the registering datacentre. For more information about this format and its schema please see the Datacite OAI schema web site.
This metadata format contains only the original DataCite metadata without additions or alterations. Because there are multiple versions of DataCite metadata in the MDS, there is no one schema that they will all adhere to. Therefore the schema for this format does not exist and metadata will not validate against it. Please note that this format is not OAI-PMH version 2.0 compliant for the previously stated reasons.
Each DataCite allocation agency and client datacentre is represented by a set in the repository. Therefore it is easy to harvest all available metadata for a particular datacentre or allocator.
You can use custom solr search queries in your setspec. Therefore the solr query string must be base64url encoded, see RFC 4648, and appended to any normal setspec or the empty string separated by a tilde (
~). There shall be no tailing padding character (
Currently the solr query params
fq are supported. For list of field names see DataCite Search Help. At the bottom of the search results on DataCite Search there is also a link to convert any custom query into a OAI-PMH request.
