Class: Pubid::Calconnect::UrnGenerator

Inherits:
UrnGenerator::Base show all
Defined in:
lib/pubid/calconnect/urn_generator.rb

Overview

Emits CalConnect URNs of the form urn:calconnect:: e.g. "urn:calconnect:DIR:10006:2019", "urn:calconnect:18011:2018", "urn:calconnect:WD:51017:2024-07-23".

The series keeps its printed case (JIS keeps its code case likewise) so a URN reconstructs the human form losslessly — mirror in urn_parser.rb.

NOTE: a partial (date-less) reference has NO round-trippable URN form. Both series and date are optional, and UrnParser reads the trailing segments positionally, so a date-less URN like "urn:calconnect:11001" (or "urn:calconnect:DIR:10006") is ambiguous with a series-less dated URN and does not parse back. Partial refs are matched by pubid #exclude, not by URN, so this generator simply omits the missing segment rather than emitting an empty ":" — callers must not rely on URN round-trip for a partial id.
