History

Formerly known as the data contract template, this standard is used to implement Data Mesh at PayPal. Starting with v2.2.0, it is maintained by a 501c6 non-profit organization called AIDA User Group (Artificial Intelligence, Data, and Analytics User Group). On November 30th, 2023, AIDA User Group and the Linux Foundation AI & Data joined forces to create Bitol. Bitol englobes ODCS and future standards & tools.
