          • Zheng ask to complement this demo with AAI, so auth/authz is also present in the architecture and exercised (milestone in WP5 is to demonstrate data access)
      • Simone will draft a skeleton agenda for the WP2/WP5 session and circulate it.
  • ESCAPE Progress Report document to be provided to the this General Assembly, need to reflect the work done and the progress done so far.
    • Simone will draft 4 pages document and circulated so can be discussed next week. We will have extraordinary a WP2 meeting next week (29th of January)

      • Gonzalo asked whether the XCache software “suite” could be deployed on Kubernettes (K8s)
        • Diego and Riccardo mentioned there are initiatives on this as containeraized methods are used in the several XCache infrastructures.
        • Xavier mentioned also the US initiatives based on Services at the Edge (SLATE) where K8s is used as well.
        • Agreed to present in detail XCache deployment topic and deployment methods in one of the following meetings (maybe after Brussels)

        • There was interest on the event happening in Lyon about Storage Events, this event is organised between DESY and IN2P3 to discuss ideas between both labs. This raised the interest of Xavier and Gonzalo that would appreciate a summary (if possible) at one of the next meetings.
      • T2.5: Andrea mentioned the hackathon organised at CERN concerning token based authorization flows for data access. This was mainly for WLCG and ESCAPE. The workshop was extremely productive and very well attended.
