## What it is
The Open Data Contract Standard (ODCS) is an open specification defining the structure of data contracts between data producers and consumers, covering schema, data quality, SLAs, pricing, and roles. It provides documentation, examples, and a JSON Schema for validating data contract files written in YAML.

## Use cases
- define a data contract between data producer and consumers
- validate data contract YAML files with a JSON schema in my IDE
- standardize data quality expectations and SLAs across teams
- adopt a common format for data mesh data products
- document dataset schemas, pricing, and support channels
- learn how to write data contracts

## When to choose
- you need a vendor-neutral, open standard for describing data contracts
- you are implementing data mesh or data product practices
- you want IDE validation of data contract definitions via JSON Schema
- you need a shared agreement format covering schema, quality, and SLAs

## When to avoid
- you need executable tooling to enforce contracts rather than a specification
- your organization already mandates a different data contract framework
- you want a runtime data quality monitoring solution
