Getting Started with OpenDPI

OpenDPI (Open Data Product Interface) is a declarative specification for defining data products. In this guide, we'll walk through creating your first data product definition.

What is OpenDPI?

OpenDPI provides a standard way to describe your data products, including:

• Metadata - Title, version, and description
• Connections - How to connect to your data sources
• Ports - The data interfaces your product exposes
• Schema - The structure of your data

Your First Data Product

Create a file called dataproduct.yaml:

opendpi: "1.0.0"

info:
  title: My First Data Product
  version: "1.0.0"
  description: A simple example data product

connections:
  main_db:
    protocol: postgresql
    host: localhost
    variables:
      database: myapp
      schema: public

ports:
  users:
    description: User information
    connections:
      - connection:
          $ref: "#/connections/main_db"
        location: users
    schema:
      type: object
      properties:
        id:
          type: integer
        name:
          type: string
        email:
          type: string

Next Steps

Once you've defined your data product, you can use the Daco CLI to validate, build, and deploy it. Check out our CLI documentation to learn more.
