A Data Contract is a formal agreement that defines expectations around a data artifact such as a dataset, a stream, etc.
- Creates a link between data producers and data consumers.
- Creates a link between a logical representation of the data and its physical implementation.
- Describes metadata & and meta-metadata: such as data quality and business rules, Service-Level Agreement (SLA), and behavior.
A data contract should be considered the source of truth for your metadata.
The Linux Foundation project Bitol has published a data contract standard called Open Data Contract Standard (OCDS)[1]. Its current version is 3.0.1.
History
On April 28th, 2024, PayPal publishes as Open Source its data contract template[2]. It came from the work that Jean-Georges Perrin and his team were doing on Data Mesh[3].
In June 2023, Andrew Jones publishes "Driving Data Quality with Data Contracts: A comprehensive guide to building reliable, trusted, and effective data platforms.[4]"
In November 2023, The Linux Foundation accepted the Bitol project that forked the work from PayPal and created the Open Data Contract Standard (ODCS)[5].
