Pattern for CURIES

Compact URIs (CURIEs) constructed from ProteomeXchange should match this regular expression:

Example CURIE
Metaregistry ProteomeXchange

The metaregistry provides mappings between the Bioregistry and other registries. There are 3 mappings to external registries for px with 1 unique external prefixes.

Registry Name Registry Metaprefix External Prefix Curate
BioContext biocontext PX logo miriam px
Name-to-Thing Name-to-Thing logo n2t px

Providers are various services that resolve CURIEs to URLs. The example CURIE px:PXD000500 is used to demonstrate the provides available for px. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.

Name Metaprefix URI
ProteomeXchange px
Bioregistry bioregistry miriam
