Class: Pubid::Etsi::UrnParser

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

Overview

Parses ETSI URNs back into identifiers.

UrnGenerator emits:

urn:etsi:{type}:{code}:{version}:{date}[:{supplement_notation}:{number}]

type is the lowercase type abbreviation (en, ets, ts, tr, gs, sr). code is the identifier code with internal whitespace preserved. version is the lowercase Vx.y.z form. date is YYYY or YYYY-MM.

Examples:

  • urn:etsi:en:300 100:v1.1.1:1998-04 → ETSI EN 300 100 V1.1.1 (1998-04)
