Steps in NCAR/UCP DOI Registration Process


Step 1: Prepare metadata for the resource(s)

  • All resources registering for DOIs are required to have associated DOI metadata.
  • When registering DOIs with DataCite, DataCite requires the use of its metadata schema. This schema has five required metadata fields and other optional metadata fields that will help in enhancing the details of the resource description.
  • The required metadata fields are:
    1. Creators
    2. Title
    3. Publisher
    4. PublicationYear
    5. ResourceType
  • The NCAR ad hoc data citation group's recommends filling out as many of the optional fields as possible. Guidance on the individual fields can be found within the following link: DataCite Metadata Schema

Step 2: Create landing page(s) for the resource(s)

  • Each DOI needs an associated "landing page".
  • A landing pages is a specific web page to which the DOI can point.
  • The landing page should at least have the information about the following:
    • The resource that is being identified
    • Information on how to access the resource
    • Citation format for the resource
  • A DOI must point to a landing page even if the resource (e.g. data sets, software) is deprecated or is replaced/superseded.

Step 3: Do you have a DataCite account?

  • The NCAR Library has purchased a membership to enable NCAR/UCP to use DataCite's DOI registration services.
  • If you plan to assign a small number of DOIs, the NCAR Library can generate a DOI for you via DataCite.
  • If you plan to assign a large number of DOIs, or want to be able to create DOIs yourself, please contact the NCAR Library at: datahelp@ucar.edu

Step 4.1: Contact the NCAR Library

Step 4.2: Choose the Registration Interface

  • DataCite provides two different interface options for the DOI registration process:
    1. DataCite DOI Fabrica, DataCite’s web-based user interface, allows individuals with valid DataCite credentials to create new DOIs and manage existing ones.
    2. DataCite’s application programming interface (API) permits machine-to-machine transactions, so that functions relating to DOIs could be integrated into other applications or systems and be performed automatically.
  • For further details of DataCite’s process and tools, please refer to DataCite’s Support page.

Additional Information and Resources about DOI


Good Practices for DOIs:

  • Citation Display: DOI landing pages should also display recommended citations for the resource being identified. For examples of data citation formats, please see:

  • User Engagement: DOIs have no purpose if they are not used in citations/references to the associated resource. It is important to engage your user community with information about your resource and the associated DOI. It is also helpful to make it very clear to users how you expect them to reference your resource.

  • Collaborative, Inter-Institutional, and Distributed Projects: In the case that a resource might involve multiple individuals from various research organizations, the project team should coordinate the responsibility and commitment to the assigned DOIs, including the DOI’s metadata content. The discussions among the project team members can also help minimize the unnecessary creation of multiple DOIs for the same resources.

  • Long-Term Responsibility: DOIs are statements of commitment. They are permanent web identifiers, intended to support persistent linking to long-lived scientific resources. Assigning DOIs thus involves a commitment to maintain the resource(s) being identified, and to ensure their long-term accessibility. Developing a concrete plan for this long-term accessibility is essential.
