Time-bound management of data access applications

Release 7 introduces functionality to support the implementation and monitoring of time limits in the application assessment process. This enables structured tracking of key procedural steps (submission, evaluation, decision), visibility on deadlines for both applicants and HDABs, compliance with EHDS timelines and more predictable processing.

For applicants

• Improved usability of the EU Dataset Catalogue : Release 7 introduces a favourites functionality allowing users to save and reuse frequently used search queries, facilitate navigation and reuse of queries results.
• Notification system : A notification service has been introduced to inform applicant of changes in application status, requests for additional information, other relevant messages from HDABs. This supports timely interaction between applicants and HDABs throughout the procedure.
• Collaborative editing of data access applications : The platform now supports multi-user collaboration on a single application. This allows multiple contributors to jointly prepare and update an application, better coordination within applicant teams, improved completeness and quality of submitted applications.

HDABs Workspace and transparency registry 

The release further develops the distinction between a public-facing registry (for transparency towards any external users), and a dedicated workspace for HDABs (supporting internal processing and tasks management). 

This supports both transparency obligations under the EHDS, and efficient handling of procedures by competent authorities.

Updates of HealthDCAT-AP and subsequent platform enhancements

HealthDCAT-AP has been updated to reflect the latest comitology discussions. This includes :
