Dear members of the SEMIC community,

The next iteration of StatDCAT AP is ready for community input, and the public review of version 3.0.0 is now officially open.
The draft specifications are now available for consultation:

• https://semiceu.github.io/StatDCAT-AP/drafts/3.0.0/
• https://semiceu.github.io/StatDCAT-AP/s1n/drafts/3.0.0/

The public review will remain open until September 2026. All interested stakeholders are warmly invited to consult the draft and contribute to its improvement. Feedback can be submitted via the StatDCAT-AP repository.

We particularly encourage members of the community to review the specifications critically, assess their applicability in real-world scenarios, and actively contribute feedback by raising issues or suggestions. Your expertise is essential to ensure the robustness, clarity, and usability of the specification.

This version introduces a range of refinements and enhancements. The consolidated changelog provides a structured overview of both editorial improvements and data model adaptations, including clearer usage guidance, alignment of terminology, and the introduction of new concepts such as Dataflow, Dataset status, and enhanced support for dataset series and multidimensional data. In addition, the s1n namespace vocabulary changelog details the evolution of the supporting vocabulary, including newly introduced properties and classes, as well as clarified domain constraints based on Working Group discussions.

We sincerely thank you in advance for your time and contributions, and we look forward to engaging with you throughout this review process.

Best regards,

The SEMIC Team
