The Proteomics Standards Initiative modification ontology (PSI-MOD) aims to define a concensus nomenclature and ontology reconciling, in a hierarchical representation, the complementary descriptions of residue modifications.

Pattern for Local Unique Identifiers

Local identifiers in Protein modification should match this regular expression:
^\d{5}$

Example Local Unique Identifier
01467   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Protein modification should match this regular expression:
^mod:\d{5}$

Example CURIE
mod:01467
MIRIAM Namespace Embedded in LUI
The legacy MIRIAM standard for generating CURIEs with this resource includes the namespaceEmbeddedInLUI as true. The actual part that gets prefixed before the local unique identifier regex, otherwise known as the banana, is MOD:. Therefore, you might see local unique identifiers written out as CURIEs.

Metaregistry Protein modification

The metaregistry provides mappings between the Bioregistry and other registries. There are 11 mappings to external registries for mod with 5 unique external prefixes.

Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE mod:01467 is used to demonstrate the provides available for mod. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
