Access the DataCite OAI-PMH service here: https://oai.datacite.org
This DataCite service exposes metadata stored in the DataCite Metadata
Store (MDS) using the Open Archives Initiative Protocol for Metadata Harvesting (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
https://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:
- Identify - used to retrieve information about the repository.
- ListIdentifiers - used to retrieve record headers from the
- ListRecords - used to harvest full records from the repository.
- ListSets - used to retrieve the set structure of the repository.
- ListMetadataFormats - lists available metadata formats that the
repository can disseminate.
- GetRecord - used to retrieve an individual record from the
Selective harvesting can be performed by the use of accompanying
parameters. Available parameters are:
- identifier - specifies a specific record identifier.
- metadataPrefix - specifies the metadata format that the records
will be returned in.
- set - specifies the set that returned records must belong to.
- from - specifies that records returned must have been
created/update/deleted on or after this date.
- until - specifies that records returned must have been
created/update/deleted on or before this date.
- resumptionToken - a token previously provided by the server to
resume a request where it last left off.
The verbs and parameters can be combined to issue requests to the
service such as:

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 and the registering data center.
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
Each DataCite member and data center is represented by a set in the repository.
Therefore it is easy to harvest all available metadata for a particular member
or data center.
You can use custom query search queries in your setspec. Therefore the
query string must be base64url encoded, see RFC 4648, and
appended to any normal setspec or the empty string separated by a tilde
The query structure is documented here: https://support.datacite.org/docs/api-queries
