Working with Previous DataCite Metadata Schemas

Current Version

The current version of the DataCite Metadata Schema is found at the DataCite Metadata Schema website. The current version is 4.1.

The most recent version of the DataCite Metadata Schema is the preferred version of the schema for DOI Fabrica and our MDS API, but many of the previous versions of the DataCite Metadata Schema are still valid.

Other Supported Versions

Retirement of Schema Versions 2.x

Beginning 1 January 2019, it will no longer be possible to register new DOIs using either DataCite Metadata Schema 2.1 or 2.2.

To register DOIs using a more recent version of the Schema, it is necessary to update the namespace submitted as part of the metadata, e.g. xmlns="http://datacite.org/schema/kernel-4".

Please review the documentation for your selected replacement Schema version to learn more about the available metadata requirements and options. In particular, please note that resourceTypeGeneral is a required field as of Schema 4.0.

Obsolete Versions (no longer supported)

Naming Convention

Starting with version 3.0 only major releases will have a new namespace, meaning that it is only necessary to specify http://datacite.org/schema/kernel-3 rather than http://datacite.org/schema/kernel-3.1, for example.

The version number is formatted as: Major.Minor

  • Major Version — A major release is for adding features that require breaking backward compatibility with previous versions or represent fundamental changes. For a major release, the MAJOR component is incremented by one and the MINOR component is set to zero, e.g. 3.1 to 4.0.
  • Minor Version — A minor release is for adding features that do not break backward compatibility with previous versions and for fixing bugs that may or may not break backwards compatibility. For a minor release, the MINOR component is incremented by one, e.g. 3.0 to 3.1.
