Module: Opencdd::Entity::NameSynthesizer

Defined in:
lib/opencdd/entity/name_synthesizer.rb

Overview

Reverse name-to-ID resolution for Parcel sheets that omit the #PROPERTY_ID directive row. Some cdd.iec.ch export formats (notably RELATION exports) include only #PROPERTY_NAME.en, leaving the importer unable to map column positions to property IDs. NameSynthesizer bridges that gap using the IEC 62656-1 defined column names.

Extracted from SheetSchema so SheetSchema focuses on header parsing + Column construction. Name synthesis is a separate concern with its own test surface.

The nameā†’ID table itself lives in Opencdd::PropertyIds::IEC_COLUMN_NAMES (the lint-exempt SSOT). NAME_TO_PROPERTY_ID is kept here as a back-compat alias so existing callers see no public-API change.

Class Method Details

.synthesize(name_values) ⇒ Object

Given a PROPERTY_NAME directive row (Array of name strings), returns a parallel Array of property IDs (or nil where the name is unrecognized). Language suffixes (.EN, .FR) are stripped for lookup and re-appended to the synthesized ID.

synthesize(["Code", "PreferredName.EN", "Unknown"])
=> ["MDC_P001_5", "MDC_P004.en", nil]
