Class: Pubid::Bsi::UrnParser

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

Overview

Parses BSI URNs back into identifiers.

UrnGenerator emits:

urn:bsi:{publisher}:{number}:{year}[:{supp_type}:{supp_number}:{supp_year}]

publisher is the lowercase publisher (e.g., “bs”, “pd”). supplement triples (‘amd`/`cor`/`add`) follow the base identifier.

Examples:

  • urn:bsi:bs:9001:2015 → BS 9001:2015

  • urn:bsi:bs:9001:2015:amd:1:2020 → BS 9001:2015/A1:2020

SUPPLEMENT_ABBR =

  "amd" => "Amd",
  "cor" => "Cor",
  "add" => "Add",
