FAIR² and Open Data Products Specification (ODPS) Integration

Overview

FAIR² (FAIR Squared) integrates with the Open Data Products Specification (ODPS) to support transparency and governance in data product design, especially for datasets reused in AI and machine learning pipelines. The integration allows FAIR² metadata to include key elements from ODPS—such as licensing and governance—through a dedicated odps property.

This alignment ensures that FAIR² metadata can support principles of openness, accountability, and stewardship that ODPS promotes, while remaining compatible with linked data and SHACL validation frameworks.

ODPS in FAIR²

A new top-level property, odps, is introduced in FAIR² to encapsulate metadata fields derived from the Open Data Products Specification.

Structure

{
  "odps": {
    "license": {
      "type": "Open Government Licence v3.0",
      "url": "https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/"
    },
    "governance": {
      "owner": "Department of Data Infrastructure",
      "contact": "opendata@example.gov",
      "oversightBody": "National Data Governance Board",
      "accountabilityMechanism": "Annual audit with public reporting"
    }
  }
}

ODPS Metadata Fields in FAIR²

Property Description
odps.license.type The name of the license under which the dataset is published
odps.license.url A URI pointing to the full license text
odps.governance.owner The organization or department that owns the dataset
odps.governance.contact Contact information for the governance authority
odps.governance.oversightBody Body or authority responsible for governance or stewardship oversight
odps.governance.accountabilityMechanism Description of processes ensuring transparency and accountability

Example: Full JSON-LD Dataset with ODPS Block

{
  "@context": "https://fair2.ai/ns/",
  "@type": "Dataset",
  "name": "Air Quality Index Dashboard",
  "description": "A dataset used in urban pollution modeling.",
  "license": "https://creativecommons.org/licenses/by/4.0/",
  "odps": {
    "license": {
      "type": "Open Government Licence v3.0",
      "url": "https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/"
    },
    "governance": {
      "owner": "Department of Data Infrastructure",
      "contact": "opendata@example.gov",
      "oversightBody": "National Data Governance Board",
      "accountabilityMechanism": "Annual audit with public reporting"
    }
  }
}

Purpose and Benefits

Including ODPS metadata within FAIR² enables:

  • Clear definition of ownership and legal reuse rights
  • Transparent data governance documentation
  • Alignment with open government and open science principles
  • Support for institutional data stewardship policies

Validation and Interoperability

  • The odps property can be validated using SHACL rules defined in the FAIR² validation profile.
  • ODPS metadata is kept modular and namespaced to allow future expansion without impacting core FAIR² properties.
  • FAIR² remains fully compatible with Schema.org, ML Croissant, and JSON-LD-based applications.
