Data contract

In data management, a data contract is an agreement between data producers and data consumers.^[1] It contains a detailed schema creating a link between business (logical representation of the data) and technology (its physical implementation). A data contract also describes advanced metadata, such as data quality rules, SLA, and behavior. Data contracts can take several forms, but YAML is very common.^[2]

The Linux Foundation project Bitol has published a data contract standard called Open Data Contract Standard (ODCS).^[3]. Its current version is 3.0.2.^[4]
