Overview

Parser for International Pharmacopoeia (Ph.Int.) JSON files

This parser creates Lutaml::Model instances (not hashes) for proper model-driven architecture. All output uses model classes.

Ph.Int. data files are JSON with embedded HTML content: { "id": "6.1.1", "title": "Abacavir sulfate (Abacaviri sulfas)", "data": { "t": "Title", "b": "

HTML body content...

", "c": [] } }
