Status update:

  • Data is being copied to /eos/opendata/delphi by the OpenData team
  • The folders tapecor and recover were held back
    • Fatfind correctly resolves them. Action item: How does it do that exactly ?
    • One contains data sampels and can be merged into the tape folder
    • The other one contains a mix of simulation.The idea is to move that into the simulation folder as is
  • A PoC is ready for automatically created Docker containers via the gitlab CI.
    • How to use them exactly ? Needs clarification with the Opendata team
    • There are a few known issues for which JIRA tickets have been created
  • Very good progress on the creation of the JSON files by Dietrich
    • The amount of data sets is significantly larger than anticipated
      • Not clear what of all this is actually useful
    • Initial version reads directly the PDL files 
    • Using pdl2pd and/or fatfind may allow to simplify the code
    • The Opendata team suggests additional meta data for each data set
      • Clarifications with them what is needed is ongoing (Dietrich)
      • Some additional information is expected to be available from the pilot records in the data itself
      • Technically it should be easy to access this info, however, it requires reading the data sets
  • Documentation:
    • Jan already provided a list with the archives from Ugo
    • Chiara will go through them to see if we can recover any missing documentations
