Publish FAIR data

Use persistent identifiers

To resolve your concepts URIs.

URLs and domain name can change fast. If you want your knowledge graph identifiers to be resolvable in a few years, it is highly recommended to use a persistent identifier service that will redirect to the URL of your concept (which can then change in time).

Popular services to publish persistent identifiers are:

• w3id.org
• purl.org

We recommend to use the w3id.org system, as it allows any GitHub user to define and reserve your persistent namespace for free in a few minutes:

1. Fork the w3id.org repository: https://github.com/perma-id/w3id.org
2. Create a folder with your namespace name (e.g. my-onto)
3. Add a .htaccess file with the redirection to your ontology (and a README.md file shortly explaining the purpose of this namespace)
4. Send a pull request to the https://github.com/perma-id/w3id.org repository. It usually takes between a few hours and a few days to be accepted.

Examples

• See this example for a .htaccess passing the original w3id URI queries
• Or this example to redirect to different websites depending on the path.

The persistent identifiers can be easily modified later if necessary, you will just need to send a new pull request with the changes.

Get a Digital Object Identifier

Optionally, for research, it is recommended to publish your resource on a repository to get a Digital Object Identifier (DOI):

• Zenodo
  • e.g. https://zenodo.org/record/4269952
• FairSharing.org
  • e.g. https://fairsharing.org/FAIRsharing.dpkb5f

Even more FINDABLE

ORCID is a good way to identify and authenticate yourself across research publishing platforms. Don't hesitate to create an account if you need it.
