Pattern for Local Unique Identifiers

Local identifiers in Universal Spectrum Identifier should match this regular expression:
^.+$

Example Local Unique Identifier

PXD002255::ES_XP_Ubi_97H_HCD_349:scan:9617:LAEIYVNSSFYK/2   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from Universal Spectrum Identifier should match this regular expression:
^mzspec:.+$

Example CURIE

mzspec:PXD002255::ES_XP_Ubi_97H_HCD_349:scan:9617:LAEIYVNSSFYK/2

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 mzspec:. Therefore, you might see local unique identifiers written out as CURIEs.

The metaregistry provides mappings between the Bioregistry and other registries. There are 4 mappings to external registries for mzspec with 2 unique external prefixes.

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.
