Class: Pubid::Nist::UrnParser

Inherits:
UrnParser::Base show all
Defined in:
lib/pubid/nist/urn_parser.rb

Overview

Parses NIST URNs back into identifiers.

UrnGenerator emits:

urn:nist:{type}:{code}[.{revision}].supp

type is the lowercase series (sp, fips, ir, nistcir, …). code is the alphanumeric designation. revision is ‘rN` when present. The `.supp` suffix marks the series as supplementable.

Examples:

  • urn:nist:sp:800-53.supp → NIST SP 800-53

  • urn:nist:sp:800-53.r5.supp → NIST SP 800-53r5

  • urn:nist:fips:199.supp → NIST FIPS 199
