Plans for 2026-2027

Strengthen WGs beyond technical implementation of tools

• Facilitate discussion on:
• Integration of IAM, Rucio, and HPC
• Metadata management
• Plans for the IVOA and path forward
• Next generation VREs: interactive vs declarative analyses
• Establish a forum for policy and strategic discussion (--> competence centre)
• Steps towards multi-messenger astronomy: how to combine signals
• The evolution of the distributed computing model for science
• Shaping the EOSC Federation while it’s still malleable

This is a PROPOSAL.

The WGs should address the needs of the community.

Suggestions on how to make them practically useful are very welcome.
