Information for interested parties of the DOI registration

If you as a scientist would like to find out more about what a Digital Object Identifier (DOI) is or if you are interested in DOI registration as a data centre, you will find basic information here.

Benefits of DOI registration

The daily work with digital resources is an essential feature of current scientific practice. In order to meet the demands of citation in a scientific context, the referenced content must be able to be found in the digital world in the long term. The reference to a URL (Uniform Resource Locator) is not optimal for this purpose, as the access location of cited content changes and the corresponding URL can thus become invalid.

The DOI system counteracts this problem by identifying an object (analog or digital) in the DOI.
This means that descriptive information on the object and its digital access point remain available regardless of the location of the resource.

A DOI is therefore a permanent and unique identifier of a scientific resource, which is directly linked to the object and linked to so-called metadata. This makes it an important building block for ensuring sustainable access to research data, publications, videos and other scientific resources.

The DOI system is an ISO standard (26324:2012) and is widely used in the scientific publication process.

Advantages of DOI registration

A DOI registration

  • makes objects unambiguously referenced and easier to access,
  • makes it easier to cite and link objects with a publication,
  • is the standard in science for the publication of scientific articles,
  • improves access to scientific data and avoids duplication.
  • raises the visibility of research data, motivates new research and encourages scientific cooperation,
  • makes digital objects such as scientific films and film segments as easy to quote as texts.

DOI Service of the TIB

The DOI service of the TIB is primarily aimed at scientific research institutions such as institutes, universities and colleges that wish to register DOI for scientific resources. The focus here is on research data of all kinds, which can be published in a variety of forms and identified with a DOI name. These can be graphics, videos, text documents, spreadsheets, software or databases. Furthermore, grey literature and articles in Open Access journals can be registered with a DOI.

The prerequisite is the conclusion of a contract between the TIB and the scientific institution. The scientific institution is responsible for this:

  1. The long-term availability and accessibility of the objects in accordance with the "Recommendations for the Safeguarding of Good Scientific Practice" of the German Research Foundation (DFG) for at least ten years.
  2. The quality of the content of the data, which is worth quoting and publication and which supports other scientists in their work.
  3. Resolving the DOI names results in a landing page and not the data itself. A landing page is usually an HTML page on which a detailed description of the data and information is available for access.

You can download the contract with annexes 1 and 2 here. Please return the completed contract in duplicate to the TIB.

Costs

There are no fees for DOI registration by the TIB for scientific institutions with their principal place of business in the EU, which receive at least 51% public funding.

Data centres that do not receive at least 51% public funding and/or whose head office is outside the EU, please refer to Appendix 1 - Cost Model (PDF).

DOI registration

After signing the DOI Deployment Agreement, you will receive access to the Metadata Store, DataCite's registration infrastructure, from the TIB.

Essential for the registration is the creation of an XML file, which contains the metadata of the object to be identified. The "DataCite Metadata Schema" must be used for this. Notes on creating the metadata can be found here (internal link to the corresponding section in "Step by Step to the DOI").

Metadata Store

The Metadata Store (also known as "MDS") allows you to register DOIs and manage the associated metadata and web addresses. To register a complete DOI in the Metadata Store, you need a DOI name, a URL of the landing page and descriptive metadata in XML format.

To register DOIs, you can use either the online form of the Metadata Store or the API interface. A detailed explanation of how to register a DOI can be found in the section "Step by step to a DOI" or in or manual "Your path to DOI registration" (PDF).

Structure of a DOI

Each DOI name is a unique sequence of alphanumeric characters and consists of two parts, the prefix and the suffix. The two segments are separated by a slash. For example, 10.12345/abc would be a complete DOI name.

After the contract has been concluded, the TIB assigns an individual prefix to the institution. The design of the suffix is then taken over by the scientific institution itself. This structure allows the institution to generate unique DOI names on its own responsibility. 

Testaccount

To test the DOI registration in the Metadata Store (MDS), the TIB offers you access to a test environment.

DOIs, which are registered via a test account, are only used for demonstration purposes and will be deleted after a certain period of time. Contact us to get the access data for the test environment.
