4 Demo 1: Submitting

• Using CAP interactive deposit forms on the Web. LHCb deposit example.
• Ingesting information from external sources (code, container images). Integration with GitLab.

5 Demo 1: Discussion

11:50 Lunch break (R2)

6 Demo 2: Automatising

• Using the CAP command line client to interact with CAP automatically
• Walk-through how to search and extract deposited information (pull)
• Walk-through how to deposit information and analysis assets
  (push)
• Walk-through how to update the information (patch)

7 Demo 2: Discussion

8 Demo 3: Searching

Display analysis records and associated information. Ingestion from collaboration sources (CMS CADI) and record enrichment (e.g. final state particles). “Intelligent” search for information such as datasets used, triggers used, final state particle objects and pt/eta cuts.

9 Demo 3: Discussion

10 Demo 4: Analysing

• REANA from the user point of view. The command line client.
• Live walk-through using a simple physics analysis example.

11 Demo 4: Discussion

14:35 Coffee break

12 Demo 5: Reusing

Reusing preserved analysis via CAP<->REANA integration. Reinstantiating preserved analysis assets and rerunning the analysis workflow. Displaying progress on CAP and downloading final plots.

13 Demo 5: Discussion
