The Universal Spectrum Identifier (USI) is a compound identifier that provides an abstract path to refer to a single spectrum generated by a mass spectrometer, and potentially the ion that is thought to have produced it.
mzspec
Local identifiers in Universal Spectrum Identifier should match this
regular expression:
^.+$
Compact URIs (CURIEs) constructed from Universal Spectrum Identifier should match
this regular expression:
^mzspec:.+$
namespaceEmbeddedInLUI
as true. The actual
part that gets prefixed before the local unique identifier regex,
otherwise known as the banana, is
mzspec:
.
Therefore, you might see local unique identifiers written out as CURIEs.
The metaregistry provides mappings between the Bioregistry and other registries. There are

Providers are various services that resolve CURIEs to URLs. The example CURIE
mzspec:PXD002255::ES_XP_Ubi_97H_HCD_349:scan:9617:LAEIYVNSSFYK/2
is used to demonstrate the provides available for
mzspec
. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
