In order to prevent the further spread of the coronavirus, the TIB is closed to the public.
We are still here for you online and by telephone, and our digital services and TIB document delivery are available as usual.
If you are already a data centre registered with the TIB, you will find practical information on DOI registration here.
There are two ways to register objects and upload metadata:
This short guide shows how to register DOIs in Fabrica's online form.
Step 1: Create a DOI name from the prefix and suffix
- Example of a DOI name: 10.12345/abc123
- The prefix is assigned to you by the TIB.
- You can design the suffix as you like.
Step 2: Create metadata as an XML file and upload it to Fabrica
- Metadata is a prerequisite for every DOI registration
- The metadata is created according to the current DataCite metadata schema.
- To be able to register DOIs, it is sufficient to fill in the mandatory fields
Any XML editor can be used to create the metadata, for example Notepad++ (free of charge).
The table below shows the three groups (required fields, recommended fields and optional fields) into which the metadata fields are divided.
|Mandatory||Identifer, Creator, Title, Publisher, PublicationYear, ResourceType|
|Recommended||Subject, Contributor, Date, RelatedIdentifier, Description, GeoLocation|
|Optional||Language, AlternateIdentifier, Size, Format, Version, Rights, FundingReference|
We recommend that you specify as much metadata as possible. The more information stored in the metadata, the better the objects can be found and used. The data of Fabrica is used by scientific search engines (e. g. BASE) or other services (e. g. ORCID).
Step 3: Specify the overview page, the so-called landing page, for the object.
- The URL of the landing page must match the domain you specified when you created the TIB's Fabrica account.
- If the location or address of the digital object changes, the URL in Fabrica is simply adapted.
DOIs consist of a prefix and a suffix. The TIB assigns one or more prefixes to you, and then you design the respective DOI suffix.
You do not need to express any specific or descriptive information in the suffix - this information is mapped to the metadata during registration. If you choose to insert bibliographic information into a DOI string, this has no meaning within the DOI system. Existing identifiers such as an ISBN, PII (Personal Identification Information) or an internal numbering scheme can also be used for the DOI suffix.
What should be considered when designing the suffix?
- Make the suffix easy to read. Remember that DOIs appear online and in print, and users re-enter DOIs.
- The optimum length of a DOI suffix is between 8 and 10 characters. This is long enough to ensure uniqueness and short enough to avoid typos
- Be clear: A suffix must be unique within a given prefix.
- Only use the permitted characters "a-z","A-Z","0-9" and "-. _; ()/".
Please note that a DOI should always be expressed as a URL. For this reason, it is recommended to keep the suffix short.
Some suffix examples are already available:
|Data centre||DOI example||Annotation|
|Data centre name |
and serial number
|TOPOI ExcellenzCluster||10.17171/1-3-632-2||Specification of a |
versioning by dashes
|Alfred Wegener Institut||10.2312/POLARSTERN- |
|Name of the journal |
and issue number
|10.3204/PUBDB-2017-01316||Internal database |
as well as year and
|European Society |
|10.1594/ECR2017/C-1433||Abbreviation of the |
data center and year
and internal identifier
As soon as the digital objects are registered, the corresponding DOIs are called by users.
Ideally, the DOI dissolves on a landing page that contains relevant information about the object (e. g. creator, year of publication, legal framework, download link of the object). Landing pages are freely accessible to everyone and can be used even if the object is no longer available or access to it is restricted. The information provided here should be both human and machine readable.
Your landing page must contain the following information:
- A complete quote
- The DOI displayed as URL
- Direct access to the full text
Example of a landing page of the Physikalisch-Technische Bundesanstalt:
Each object registered with a DOI receives descriptive metadata. We offer you a simple form for registering your properties.
The form does not require any XML knowledge and is suitable for a small number of registrations. You can use this form to register journal, book, conference, report and dissertation content. In addition, existing XML files can be uploaded and edited.
