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 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 Protein modification, the banana looks like MOD:. Therefore, you may see local unique identifiers for this resource that look like MOD:01467 (instead of the canonical form 01467) and CURIEs for this resource that look like MOD:MOD:01467 (instead of the canonical form MOD:01467). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.
