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 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.

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

When using this resource in RDF, the following URI format should be used:

http://purl.obolibrary.org/obo/MOD_$1

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

Additional providers curated in the Bioregistry are listed here.
