Overview

Base class for flavor-specific URN parsers.

A UrnParser inverts its sibling UrnGenerator: it consumes the URN emitted by {Flavor::UrnGenerator} and rebuilds an Identifier. The preferred strategy is to reconstruct a human-readable identifier string from the URN fields and delegate to the flavor’s text parser —this keeps parsing logic in one place (the flavor’s text parser).

Subclasses MUST override #parse_urn. They typically use #strip_namespace and #flavor_parse helpers and may pass through #build_from_parts for the common ‘urn:flavor:publisher:type: number:year` shape.
