pub.mdw | Depositor Guide

pub.mdw enables depositors meeting the depositing criteria to submit publication records to our Open Access repository. You can either create new publication records or enhance existing ones (e.g. records harvested from Open Access search engines).

In general, a pub.mdw record consists of

  1. a PDF version of the actual publication and
  2. a set of metadata

PDF document

pub.mdw supports all types of  Portable Document Format (PDF) documents with a max. file size of 100 Mb.

As pub.mdw focuses on archiving and preservaton PDF/A compliance is highly recommended.

For questions on generating PDF documents that enable long-term preservation, please contact the ZID service center.


Metadata plays a crucial role for making data FAIR (Findable, Accessible, Interoperable, Reusable). pub.mdw needs to collect some metadata on the publications, in order to make the data findable, create a persistent identifier, and disseminate the data.

The default language of the metadata in pub.mdw is English. If another language is used, the respective information must be provided in English too (e.g. title of publication or abstracts).

Every entity, may it be the publication itself, an author, a funder or a research organization involved should be uniquely identifiable.

The following information must be provided by the depositors when creating new publication records:

  1. Resource Type (e.g. book or journal article),
  2. Title (as stated on the publication) / subtitle (if needed)
  3. Language
  4. Publication Year
  5. License
  6. Creator(s) / Contributor(s) (if needed)
  7. preferred pub.mdw DOI

Additional metadata may be required for specific types of documents.

Resource Type

Select the appropriate Resource Type from the type list. The list includes the relevant entries from the Controlled Vocabulary for Resource Type Genres (Version 2.0) and can be extended by FaBiO, the FRBR-aligned Bibliographic Ontology terminology (Semantic publishing).

Please note: On DOI creation the Resource Type General will be the main classifier "text" and the description the actual selection from the pub.mdw list.

Tite / Subtitle

Please provide the title (and subtitle if needed) as stated on the publication (in the original language).


The language of the publication. Orderable.


In the creators tab please provide information on the (corresponding) authors of the content. If a person record is already available in pub.mdw, simply select the respective entry. Otherwise create a new person record and select differentiated person. Add Open Researcher and Contributor ID (ORCID), which is compatible with the ISO Standard ISO 27729 - Information and documentation — International standard name identifier (ISNI) and/or the Gemeinsame Normdatei (GND) identifier if available. Additionally add the affiliation of the creator. When adding a new affilition organization please provide a Research Organization Registry (ROR) or Global Research Identifier Database (GRID) identifier.

Please note: Only 25 creators can be stored with Datacite when registering DOIs.


Other persons and organizations involved can be stored as Contributors. Roles CRediT (Contributor Roles Taxonomy) and Datacite Contributor Types also used in  OpenAIRE Guidelines for Literature Repository Managers - ContributorTypes. pub.mdw provides a definition of these contributor types.

Datacite allows up to 8000 - 10000 names in the contributors list.

Preferred DOI
