^[\d.]+$

Example Local Unique Identifiers
2.16.840   Resolve
2   Resolve
2.16   Resolve
2.16.840.1   Resolve
2.16.840.1.113883   Resolve

Pattern for CURIES

Compact URIs (CURIEs) constructed from ISO Object Identifier should match this regular expression:
^oid:[\d.]+$

Example CURIEs
oid:2.16.840
oid:2
oid:2.16
oid:2.16.840.1
oid:2.16.840.1.113883
oid:2.16.840.1.113883.6
oid:2.16.840.1.113883.6.88
