The Ontology Working Group is a group that is working under the umbrella of the Technical Governance Board (TGB) of the AI on demand platform, but with “independent workflows".​

The expected outcomes of this Working Group are:​

• To avoid replication of work across projects on ontologies ​
• To seek a "common ontology" to support the future AI on demand platform and related projects, such as the ICT 49 projects. To reach an agreement on technologies to be used​
• To make the knowledge discoverable across platforms
• To incorporate trustworthy AI topics related to the knowledge classification
