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:
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:
- Fork the w3id.org repository: https://github.com/perma-id/w3id.org
- Create a folder with your namespace name (e.g. my-onto)
- Add a
.htaccessfile with the redirection to your ontology (and a
README.mdfile shortly explaining the purpose of this namespace)
- 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.
The persistent identifiers can be easily modified later if necessary, you will just need to send a new pull request with the changes.
Optionally, for research, it is recommended to publish your resource on a repository to get a Digital Object Identifier (DOI):

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.
