The Pathway Ontology captures information on biological networks, the relationships between netweorks and the alterations or malfunctioning of such networks within a hierarchical structure. The five main branches of the ontology are: classic metabolic pathways, regulatory, signaling, drug, and disease pathwaysfor complex human conditions.

Pattern for Local Unique Identifiers

Local identifiers in Pathway ontology should match this regular expression:
^\d{7}$

Example Local Unique Identifier
0000423   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Pathway ontology should match this regular expression:
^PW:\d{7}$

Example CURIE
PW:0000423
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 PW:. Therefore, you might see local unique identifiers written out as CURIEs.
