AODM is an open vocabulary for representing knowledge on the web — entities, relationships, facts and rules — in a form both people and AI systems can read, validate and exchange.

Apache 2.0. The repo has the XML Schema and JSON Schema, the HTML embedding profile for putting it on pages you already publish, worked examples, reference parsers in Python, JavaScript, Java and C#, a graph compiler and inference engine, an XBRL converter, and a conformance suite that requires all 4 parsers to agree.
