Joint CERN Analysis Preservation DASPOS RECAST workshop 2017

When: February 2nd 2017

Where: CERN, Room 3-R-002 (close to R1); physical presence preferred; virtual participation possible if needed

How long: 1 day; 9.30AM to ca. 5PM

Who should come: delegates from the LHC collaborations, core CAP/RECAST/DASPOS team, everyone who is interested in reproducible research

Abstract

The aims of this mini workshop are:

• getting community members together to give feedback on the first prototype of CERN Analysis Preservation (CAP) and its connection with RECAST and DASPOS work.
• special emphasis will be given to the three high-level use cases of CAP: describe, capture and reuse a physics analysis.

Dedicated sessions will allow a more detailed discussion of functionalities and expectations from the community to inform the roadmap of the services/tools/integrations.

Based on the demonstration of the recent prototype most of the day will be spent on a discussion of the next steps. Examples include, but are not limited to:
Analysis submission, are we missing out on any types of analysis, What is needed (beyond RECAST) for reuse/reinterpretation, what is needed or interesting to do on top of CAP, how can tools be connected (for example connected to CAP), search terms of interest, etc.

Notes from the workshop are available

Proposed workshop agenda

Start: 9.30AM, End: around 5PM

9.30AM to 10.30AM: Introduction

• Welcome and round of introduction
• Introduction (@suenjedt)
  • What are we trying to do? Introduce topics of data/knowledge preservation, reproducibility
  • What is our role?
    • CAP: describe, capture, reuse
    • DASPOS: Data and software preservation, reuse, execution
    • RECAST: reuse/re-interpretation, execution
  • What is the community's role?
  • What are we trying to achieve today?

Focused Discussions on "Describe, Capture, Reuse": current state, missing pieces and roadmap:

10.30 to 11.30 AM: Describe

• Overview of "Describe" pillar activities. (@suenjedt)
