Pattern for Local Unique Identifiers

Local identifiers in Software Heritage should match this regular expression:
^[1-9]:(cnt|dir|rel|rev|snp):[0-9a-f]+(;(origin|visit|anchor|path|lines)=\S+)*$

Example Local Unique Identifier

1:rev:309cf2674ee7a0749978cf8265ab91a60aea0f7d   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Software Heritage should match this regular expression:
^swh:[1-9]:(cnt|dir|rel|rev|snp):[0-9a-f]+(;(origin|visit|anchor|path|lines)=\S+)*$

Example CURIE

swh:1:rev:309cf2674ee7a0749978cf8265ab91a60aea0f7d

MIRIAM Namespace Embedded in LUI

The legacy MIRIAM standard for generating CURIEs with this resource annotates the namespaceEmbeddedInLUI as true. This means that you may see local unique identifiers that include a redundant prefix and delimiter (also known as a banana) and therefore look like a CURIE. For , the banana looks like swh:. Therefore, you may see local unique identifiers for this resource that look like swh:1:rev:309cf2674ee7a0749978cf8265ab91a60aea0f7d (instead of the canonical form 1:rev:309cf2674ee7a0749978cf8265ab91a60aea0f7d) and CURIEs for this resource that look like swh:swh:1:rev:309cf2674ee7a0749978cf8265ab91a60aea0f7d (instead of the canonical form swh:1:rev:309cf2674ee7a0749978cf8265ab91a60aea0f7d). The Semantic Farm will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

Mappings from records in Semantic Farm to external registries comprises the metaregistry. This resource has 3 mappings to external registries with 1 unique external prefixes.

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier 1:rev:309cf2674ee7a0749978cf8265ab91a60aea0f7d is used to demonstrate the providers available for Software Heritage. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
