The following article introduces the trusty URI approach:

Generally, trusty URIs are URIs that contain a certain kind of hash value that can be used to verify the respective resource. This is an example of a trusty URI:

The last 45 characters of this URI (everything that comes after r1.) are the artifact code of the trusty URI. The first two characters of the artifact code (RA in this example) define the type and version of the module. (Only FA for plain file content and RA for sets of RDF graphs are supported at this point.) The remaining 43 characters are the actual hash value. This hash can be used to check the content of the resource this URI represents.


There are currently three (partial) implementations:
