The CATH database is a hierarchical domain classification of protein structures in the Protein Data Bank. Protein structures are classified using a combination of automated and manual procedures. There are four major levels in this hierarchy; Class (secondary structure classification, e.g. mostly alpha), Architecture (classification based on overall shape), Topology (fold family) and Homologous superfamily (protein domains which are thought to share a common ancestor). This colelction is concerned with superfamily classification.

Pattern for Local Unique Identifiers

Local identifiers in CATH superfamily should match this regular expression:
^\d+(\.\d+(\.\d+(\.\d+)?)?)?$

Example Local Unique Identifier
1.10.10.200   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from CATH superfamily should match this regular expression:
^cath.superfamily:\d+(\.\d+(\.\d+(\.\d+)?)?)?$

Example CURIE
cath.superfamily:1.10.10.200
Metaregistry

The metaregistry provides mappings between the Bioregistry and other registries. There are 3 mappings to external registries for cath.superfamily.

Registry Name Metaprefix External Prefix
Identifiers.org miriam cath.superfamily
Name-to-Thing n2t cath.superfamily
Prefix Commons prefixcommons CATH.SUPERFAMILY
Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE cath.superfamily:1.10.10.200 is used to demonstrate the provides available for cath.superfamily. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
