DOI registration

Metadata schema

Every DOI name is linked to a set of metadata; a collection of bibliographical and content information, referring to the registered dataset (title, author, publication date, copyright etc.) more.

Here you can find a brief description as well as a detailed documentation of the da|ra metadata schema version 3.1 (Released November 19th, 2014) plus the xsd schema and xml examples for all resource types. Please note that da|ra Metadata Schema Version 3.0 (see Archive) is still valid and can also be used.
