Pattern for Local Unique Identifiers

Local identifiers in Logical Observation Identifiers Names and Codes should match this regular expression:
^(\d|\w)+-\d$

Example Local Unique Identifier
LL379-9   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Logical Observation Identifiers Names and Codes should match this regular expression:
^loinc:(\d|\w)+-\d$

Example CURIE
loinc:LL379-9
Pattern for RDF URIs
