D2standarden

D2standarden is a standardized framework that governs data exchange and interoperability between organisations. It provides a common set of data models, metadata schemas, interface specifications, and governance processes intended to support efficient, secure, and scalable information sharing across sectors.

Developed and maintained by a consortium of public authorities, industry partners, and standards bodies, D2standarden follows a lifecycle that includes public consultation, pilot implementations, and periodic revisions. Updates are published to reflect new requirements, technologies, and lessons learned from real-world use.

The technical scope includes data models for core entities, naming conventions, metadata fields, API contracts, authentication and authorization requirements, auditing, and accessibility criteria. It also encourages alignment with international standards where relevant and promotes the use of open formats to enhance interoperability and future-proofing.

Adoption is strongest in public administration and large-scale ICT projects, but many private organisations adopt it to meet procurement criteria and to simplify integration with partners. Implementation often requires changes to data governance, system architecture, and service level agreements, as well as training for staff and adjustments to procurement processes.

Critics argue that the standard can be complex and costly for small organisations, and that updates may create backward-compatibility challenges. Proponents emphasise its potential to reduce vendor lock-in, improve cross-border collaboration, and streamline multi-party data exchanges.

Related standards include other elements in the D-series and general interoperability standards such as JSON, REST, and OpenAPI, which are often used in conjunction with D2standarden to enable practical integration.
