OpenDPI

Think of OpenDPI as OpenAPI, but for data products. It's a simple, vendor-neutral way to describe what your data product actually is — what data it exposes, where that data lives, and what it looks like.

No more tribal knowledge. No more guessing what columns exist. Just a clean YAML (or JSON) file that tells the whole story.

Why OpenDPI?

• One spec, any platform — Works with Postgres, Snowflake, BigQuery, Kafka, S3, whatever you've got
• Self-documenting — Your data product definition is the documentation
• Automation-ready — Generate code, docs, and configs from a single source of truth
• Schema validation — Catch problems before they hit production

Quick Example

Here's what a data product looks like:

opendpi: "1.0.0"

info:
  title: Customer Analytics
  version: "1.0.0"

connections:
  warehouse:
    type: snowflake
    host: myorg.snowflakecomputing.com

ports:
  customers:
    description: Active customer profiles
    connections:
      - connection: "#/connections/warehouse"
        location: analytics.customers
    schema:
      type: object
      properties:
        id:
          type: integer
        email:
          type: string
        signup_date:
          type: string
          format: date

That's it. Your data product is now defined, documented, and ready to use.
