→ Europe/Zurich
ZOOM

ZOOM

The event will be held as virtual workshop via ZOOM.
Cristinel Diaconu (CPPM, Aix-Marseille Université, CNRS/IN2P3 (FR)), Dirk Duellmann (CERN)
Description

This is the third DPHEP Collaboration Workshop (following the many organised by the DPHEP Study Group) and will also host a Collaboration Board meeting. The workshop is organised in coherence with the respective WLCG working group.

The goals of this workshop are:

  1. Provide an update on the changing (or changed) landscape, e.g. FAIR data management (plans), reproducibility, sustainability of data repositories, an update on the status of OAIS and related "standards" and so forth.
    • Describe the "new world order" wrt "data stewardship / curation / preservation"
  2. Status reports of the services and ongoing developments in the area of LTDP and their outlook
    • Many of these are now are ramping-up as production services
  3. Perform a site-experiment round-table to capture the current situation including common problems & solutions HEP-wide
  4. Start the preparation of two documents:
    1. Letter to labs/executive summary
    2. DPHEP status report 2022 (update of 2012 document)

        How do/could experiments / sites collaborate to manage the impact from evolution/retirement of
        - site services
        - external software dependencies
        on preserved analysis chains?

        CERNLIB (discussion) 30m

        Several CERNLIB ports are still being used / maintained and face the impact of upcoming hardware and OS changes:

        • what are the main risks/benefits of independent ports?
        • is there overlap between different projects? or components that do not require active maintenance as they are superseded?
        • would community maintenance / validation be possible / desirable?
        • can we learn from other communities for how to make this more sustainable?
