The IUPAC International Chemical Identifier (InChI, see MIR:00000383) is an identifier for chemical substances, and is derived solely from a structural representation of that substance. Since these can be quite unwieldly, particularly for web use, the InChIKey was developed. These are of a fixed length (25 character) and were created as a condensed, more web friendly, digital representation of the InChI.
Local identifiers in InChIKey should match this
Compact URIs (CURIEs) constructed from InChIKey should match
this regular expression:
The metaregistry provides mappings between the Bioregistry and other registries. There are
4 mappings to external registries for
2 unique external prefixes.
|Registry Name||Registry Metaprefix||External Prefix||Curate|
Providers are various services that resolve CURIEs to URLs. The example CURIE
is used to demonstrate the provides available for
inchikey. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
