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.

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 annotates the namespaceEmbeddedInLUI as true. This means that you may see local unique identifiers that include a redundant prefix and delimiter (also known as a banana) and therefore look like a CURIE. For Universal Spectrum Identifier, the banana looks like mzspec:. Therefore, you may see local unique identifiers for this resource that look like mzspec:PXD002255:ES_XP_Ubi_97H_HCD_349:scan:9617:LAEIYVNSSFYK/2 (instead of the canonical form PXD002255:ES_XP_Ubi_97H_HCD_349:scan:9617:LAEIYVNSSFYK/2) and CURIEs for this resource that look like mzspec:mzspec:PXD002255:ES_XP_Ubi_97H_HCD_349:scan:9617:LAEIYVNSSFYK/2 (instead of the canonical form mzspec:PXD002255:ES_XP_Ubi_97H_HCD_349:scan:9617:LAEIYVNSSFYK/2). The Bioregistry will automatically strip off the banana when standardizing local unique identifiers and CURIEs.

The metaregistry provides mappings between the Bioregistry and other registries. There are 4 mappings to external registries for this resource 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 this resource. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
