Metadata Working Group

The key to making data citable, searchable and accessible is equipping datasets with metadata – descriptions of and facts and figures about the data – that meets basic standards and adheres to uniform, consistent schema. The Metadata Working Group determines and maintains DataCite’s metadata standard, in consultation with DataCite members and under the guidance of the DataCite Board. The working group actively seeks the broader community’s input and coordinates with community standards, such as ORCID, Open Funder Registry, IDF and DCMI.

The current members of the Working Group are:

  • Madeleine de Smaele, TU Delft Library (co‐chair of working group)
  • Joan Starr, California Digital Library (co‐chair of working group)
  • Jan Ashton, British Library
  • Amy Barton, Purdue University Library
  • Noris Birt, National Research Council Canada
  • Stefanie Dietiker, ETH Zurich
  • Jannean Elliott, U.S. Department of Energy/Office of Scientific & Technical Information
  • Martin Fenner, DataCite (Technical Director)
  • Wim Hugo, South African Environmental Observation Network
  • Stefan Jakobsson, Swedish National Data Service
  • Isabel Bernal Martínez, Oficina Técnica de DIGITAL-CSIC
  • Jessika Rücknagel, German National Library of Science and Technology (TIB)
  • Mohamed Yahia, Institute for Scientific and Technical Information - French National Center for Scientific Research
  • Frauke Ziedorn, German National Library of Science and Technology (TIB)
  • Lisa Zolly, United States Geological Survey (USGS)

Versioning

For our Metadata store all these versions are valid, although only one version is considered preferred at any given moment of time. Starting with version 3.0 only major releases will have a new namespace.

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.

Each incoming Metadata store XML document should indicate the schema location in the root element.

Each available version of a schema is a subdirectory containing a set of files. These files constitute a single metadata version. They include all the required xsd files, sample xml files and documentation. The files don’t reference any other files outside of their version subdirectory.

Obsolete Versions

These versions are no longer accepted by the DataCite MDS.
