A submission is a compilation of research data created by a user for archiving, which is currently in the submission process. It contains all files to be archived, metadata and information for publication. After completion of the submission process, the submission will become an archival data package.

Data Package

Data packages are submissions that went through the submission process and were archived. They are part of a data collection.


Schools represent the official structures of the universities. They can contain further organisational sub-structures or projects.


Projects are a part of an organisational structure and represent research projects (e.g. a third-party-funded project or a PhD thesis). They are described by metadata and can contain data collections and/or other subprojects.

Data Collections

Data collections are part of projects and are collections of data sets (e.g. for one topic).

Submission process

The submission process is the process including the creation of the submission (selection of files, creation of the metadata and information for publication), the review and the archiving of the submission.

Review process

The review process is part of the submission process. Two reviews (contentwise and technical) are required for each submission, in which the submission will either be accepted or referred back to the submitting user for correction. The user then has the option to complement the submission and to have it re-reviewed. After the successful completion of the review process, the submission is archived.


The review of a submission assures the quality of the archived and possibly published data packages. The content of the submission is checked for accuracy and completeness as well as the technical suitability for archiving.


The archiving of a submission takes place after the end of the review process. The files belonging to the submission and the metadata are combined in an AIP (Archival Information Package) and are stored in several copies in spatially separated tape archives. The format and the duplication of the AIP will ensure long-term preservation and recoverability of the archived data.


Metadata are data, that describe the characteristics of other data or objects in a structured way.

Open Access

Open Access describes the free access to data. Data with an Open Access licences should be available publicly and free of charge in the Internet. The exact regulations on the use of Open Access data are descriebed in the license of the data.

More information (german):


German copyright law stipulates that a work of art may only be used by its creator, unless he/she grants rights of use to others. To allow third parties the use of scientific data, i.e. to allow free access (Open Access), the licensing of the data with an Open Access license (e.g. Creative Commons) is required.

Of course, other, possibly more restrictive licenses are also possible.

Creative Commons (CC)

Creative Commons licenses are licenses that are particularly suitable for the licensing of research data as Open Access. They allow the use of the licensed data by third parties under easily understandable and individually combinable conditions.
