DOI and metadata

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

Via the metadata the DOI name presents not only an identifier, but also provides additional relevant information about the dataset, thus becoming an important tool for data management and exchange.

The metadata as well as the DOI name itself, to which it is allocated, are permanently linked with the digital object described. This makes it easy to bring into the research process, for example, when citing primary data. This equally enhances the reproducibility of the research process considerably. Metadata is also a key element for our DOI-based services like databases and the available search options.

Ensuring that metadata is persistent does not exclude its modifiability: data producers have the opportunity to amend the metadata describing their datasets (for example in case the primary URL where the DOI name resolves has been modified, etc.) whenever and as often as needed.
