OPEN SOURCE LICENSING STATEMENT
Metadat-AI (METADAT-AI LTD) | Version 1.3 | October 2026
1. PURPOSE AND SCOPE
This Open Source Licensing Statement ("Statement") identifies the principal open-source software components incorporated in or used by the Metadat-AI Platform, API, and related services ("Software"), and sets out the open-source licence under which each component is used. It is published pursuant to the obligations of those licences and is incorporated by reference into Metadat-AI's Customer Terms and End User Licence Agreement.
Metadat-AI uses only open-source components whose licences permit commercial use. Metadat-AI aims to update this Statement following each significant release of the Software and is published at www.metadat-ai.com/legal/policies/oss. Full licence texts and notices are included in each distribution of the Software under /licences/.
2. PROPRIETARY COMPONENTS AND IP POSITION
The following elements of the Software are proprietary to METADAT-AI LTD and are not open source:
• The Metadat-AI Platform application code, APIs, and integration layer.
• Custom model weights, fine-tuned models and proprietary training pipelines developed by Metadat-AI.
• All documentation, user interfaces, trademarks, and brand assets.
• Metadat-AI-generated metadata schemas, ontologies, and classification taxonomies.
