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:

Example Local Unique Identifier
01467   Resolve
Pattern for CURIES

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

Example CURIE
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.

The metaregistry provides mappings between the Bioregistry and other registries. There are 8 mappings to external registries for mod.

Registry Name Metaprefix External Prefix
BioPortal Prefixes bioportal PSIMOD
Gene Ontology Registry go PSI-MOD miriam mod
Name-to-Thing n2t mod
OBO Foundry obofoundry MOD
Ontology Lookup Service ols mod
OntoBee ontobee MOD
Prefix Commons prefixcommons MOD

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.
