Research data

Who can publish in Gutenberg Open Science?

Research data by members of the JGU can be included.

Which research data can be included in Gutenberg Open Science?

Suitable research data formats are, for example:

  • Dataset
  • Image
  • Sound
  • Movie
  • Software
  • Model
  • Other research data type

Research data related to master's theses may be included in Gutenberg Open Science by way of exception and upon special recommendation of the supervisor. We do not publish research data related to bachelor's theses or term papers.

Which requirements must my research data meet?

The following requirements must be met to be published on Gutenberg Open Science:

  • The author assures that no rights of third parties are violated by the publication and assumes liability for the content of the publication in case of an infringement.
  • The intellectual property of others is identified as such. Received ideas and quotations are identified as such.
  • In the case of illustrations, representations and tables from external media, the author must have the consent of the copyright holder for publication.
  • On the basis of the specified licenses, the author determines that the publication may be made freely available on a permanent basis.

Information on good scientific practice can be found on the pages of the project Academic Integrity or in the DFG recommendations (each in PDF format).

Which file formats are supported and what is the maximum filesize for a single uploaded file?

If the system does not automatically detect the format of the file you uploaded, a yellow/orange exclamation mark will appear next to the status. Then please click on "Next". In the following window you will get the information "File Format: Unknown (unsupported)" and please click on "Change Format" on the right side. Here you can now select either the appropriate format or the software with which the file was created from the dropdown menu. If the format/software does not appear in the list, please describe the file format in the "File Format" field to the right. Enter the name and version of the application used to create the file, e.g. MyApplication version 1.5.

For more information about file formats, see Gutenberg Open Science Supported Formats. Please note, that the maximum filesize for a single uploaded file is 4 GB MB. If one of your files is larger, please contact us beforehand.

Which licenses play a role on Gutenberg Open Science when publishing research data?

The publication on Gutenberg Open Science is done under a standardized license of the University of Mainz (Deposit License). In addition, by granting a Creative Commons License (CC License), you can specify the modalities of subsequent use of your publication by third parties. The license granted to the University of Mainz and a CC license have in common that both contain copyright regulations. However, they concern different legal relationships.

As the term Deposit License implies, this is a deposit or archiving license. A written agreement ("licence") regulates the rights and obligations between authors and the University Library. You can view and download this license agreement here. Authors transfer the simple right of use of the publications to the University Library. Thus, publication on Gutenberg Open Science does not prevent further publication in journals or monographs or in other electronic systems.

The licenses, such as the CC Licenses, determine the relationship to the readers of the publication. This defines the conditions under which the copyrighted content may be used. Here you have the possibility to decide between different concrete types of use (e.g. to copy, to save or to make digitally accessible).

IMPORTANT : Once the document has been published on Gutenberg Open Science, the selected license cannot be changed.

Can I impose a time embargo (blocking period) on my research data?

A time embargo defines a period of time during which the research data and its metadata have already been uploaded to the system but are not yet available for viewing or downloading. An embargo can be used if research data are to be published with a time delay (e.g. as part of a peer review process, to meet publisher requirements or in the case of data that has not yet been fully evaluated).

You can conveniently enter the embargo period yourself in the upload process. This embargo period applies to the entire data set (research data + metadata).If research data is published in multiple files, different embargo periods can be assigned to the individual files after uploading. If you have any questions about this please contact us:

IMPORTANT : If you want to extend the embargo again, please contact us at least 4 weeks before the expiration of the embargo period:

What are checksums in the upload process?

Gutenberg Open Science generates an MD5 checksum for every file it stores; we use this checksum internally to verify the integrity of files over time (a file's checksum shouldn't change). You can use this checksum to be sure what we've received is indeed the file you've uploaded.

If you wish to verify the file using checksums, click "Show checksums" on the "Uploaded File" page. The Gutenberg Open Science-generated MD5 checksum for every file we've received from you will show to the right of the filename. You will then need to use a local program to generate your own checksum for these files, and verify that your results match ours. On most UNIX-like systems (including Mac OS X), use md5sum. For instance, type "md5sum MYFILE" for every file you want to check; the summary should print on your screen. For Windows machines, MD5 tools are freely available: try md5 (from, or md5sum, available via the textutils package in Cygwin ( All of these utilities will need to be run from a command-line, or terminal, window. The entire digest printed out when you run the md5 tool on your local copy of the file you're uploading should be exactly equal to what Gutenberg Open Science reports.

What does the university library do and are there costs involved?

These services are free of charge for authors.

What does "content indexing" on Gutenberg Open Science mean?

A description of the content is created for all documents. The following options are available:

  • Abstract of each document in German and/or other languages
  • Subject assignment of the document according to the classes of the DDC classification

The description of the content is done in the input form by the authors, it is not edited by the University Library.

What do I have to do to publish my research data?

Please follow these steps:

  • You can find the Gutenberg Open Science repository at
  • Go to the "Publish" link there.
  • Log in with your university account.
  • Click on the button "Start a new Publication" and select the collection "JGU-Forschungsdaten" .

Your consent to the storage of data by the DNB and to any necessary technical data migrations is granted with the Deposit License. You will find more detailed information on this on the page Rights Notices and Licenses.

Can publications that have already been published be blocked or deleted?

Once published and released, documents and research data can only be blocked or deleted in exceptional cases (especially in the case of legal obstacles). The corresponding blocking form can be downloaded here. Any costs incurred for the deletion are to be borne by the authors. In the case of a publication to be deferred, the appropriate form can be found here.

What if I want to publish a revised version of my publication or my research data?

A revised version of an already published document or research data is made available as a separate publication on Gutenberg Open Science.

How is Gutenberg Open Science technically implemented?

The technical implementation of Gutenberg Open Science is based on DSpace, an internationally distributed open source software for publication and data repositories.
