    2) James Perry will email Rucio developers to start a discussion about getting Rucio included in CVMFS (general software area).
    3) Alessandra will start a discussion in the storage group (and include David Crooks), regarding requesting host certificates.
    4) Wenlong to start an email regarding sharing RAL Logs with ECDF.

        Work on multi-VO Dirac Rucio integration continues. It is based on Belle 2 implementation.
         
        There are 3 main components:
        1) RSE and user synchronisation agent.
            The agent runs periodically and reads SE and user data from Dirac  Configuration System and defines/updates RSEs and users in Rucio. It is done on the VO by VO basis. Completed.
         
         
        2) RSS - RSE status synchronisation. Similar to 1), but it updates a status of a RSE when it changes in Dirac. Multi-VO enabled. Completed.
         
        3) Rucio File catalog client. Once RSEs and users are defined work on modifying the client for multi VO can start. In progress.
         
        We use a test Dirac server and  Multi VO Rucio server at IC.
