Data Contracts

Data Contracts are agreements governing data exchange, ensuring transparency and reliability. Blindata supports them through contract management, standardization, compliance enforcement, and monitoring.



Data contracts are agreements between producer and consumer applications that rule both data and how it is exchanged. They provide transparency over dependencies and data usage across a data architecture. This increases consistency, clarity, reliability and quality of data.

Data contracts allows data products to have clear interfaces exposed to their consumers that formally specifies the scope, the provided services, and how to access them.


Blindata offers a set of features that facilitates the definition, the validation and the monitoring of data contracts.


Handle collaboration between producers and consumers with Blindata Stewardship and Responsibilities module.


Promote standardization through the adoption of a data product descriptor specification.


Prevent bad practice and ensure compliance to the descriptor specification using federated computational policies.

Prevent Breaking Changes

Avoid disruptive changes with policies enforcing before data products deployment.


Use Blindata Observability and Quality module to monitor the data assets specified in the data contract.

How to

Standardization can be achieved through the adoption of a data product descriptor specification, which should be:

  • Tech Agnostic: Compatibility with any technology stack.
  • Incrementally Adoptable: Capability for gradual adoption.
  • Declarative and Modular: Description of data appearance, not production, with modularity.
  • Extendable: Flexibility to accommodate custom properties and integrate with external standards.

The descriptor released by the Open Data Mesh Initiative meets all of this needs, offering an open source specification for describing data products: a broader concept of service agreement, with data contracts being a specific case.

Utilize the Blindata to create and implement computational policies across a diverse range of technologies, without being tied to any specific platform or language. With its tech-agnostic approach, Blindata allows you to define policies that suit your exact requirements, irrespective of the underlying tools or systems in use. Gain the advantage of centralizing all your policy code in one easily accessible location, simplifying management and maintenance.

Verify policy compliance during data product lifecycle to monitor:

  • Compliance of the descriptor to the specification to promote standardization.
  • Cloud resources configured according to governance policies data location, backup, security features.
  • And many other use cases…

This can be implemented using Open Data Mesh Platform, which is an open source data-ops platform that manages the full lifecycle of a data product from deployment to decommissioning.

A comprehensive monitoring approach is applied to a data contract, encompassing validation of its metadata via computational policies supported by the Blindata, and evaluation of its data through quality controls provided by the Blindata Quality module.
