Class: Pubid::Astm::UrnParser

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

Overview

Parses ASTM URNs back into identifiers.

UrnGenerator emits:

urn:astm:{publisher}:{code}:{year}[:sub_year][:reapp.X][:eX][:wip][:wk.X]

The publisher slot is the lowercase publisher string (“astm” or “pub-copub”). The code slot is the alphanumeric ASTM code (e.g., “D2148”, “A1”). Year is **2 digits** in the URN.

Examples:

  • urn:astm:astm:D2148:2022 → ASTM D2148-22

  • urn:astm:astm:A1:2002 → ASTM A1-02
