The name of the file, alice-2010-pbpb.json, looks very generic. Will there be more records in the same file? Or will there be other files? In which case it would be good to name it more specifically.

The current name is LHC10h_000139510_PbPb_7.0TeV_205656_record.json
I've been told that there will be a single run per record.
Let me know it there is something to change.

The value of created field should be just a year.

For heavy-ion physics data, we should add also the keyword information:

    "keywords": [
      "heavy-ion physics"
    ],

what would be the algorithm behind this? anything that is not pp then it's heavy-ion?
how will be the treatment for Xe-Xe, O-O, or p-Xe or p-O?

Note that this does not look consistent with the old existing titles such as "LHC2010h_PbPb_ESD_138275". Shall we harmonise them?

I was pointed to such a name: {PERIOD}_{RUN}_{BEAMTYPE}_{ENERGY}_{COLLISIONS_NR}
This data is converted data to O2 ALICE framework, there are no longer ESD/AOD present, only AO2D.root files. Let me know if different name is required and with what content.

For the former ALICE records, the description used to say "Pb-Pb data sample" instead of "lead". Another cosmetic observation for harmonising.

Ok, let's get back to symbolic name. How should pp look in this phrase? Pp, PP, or pp ?

The updated field should not be present in the record JSON.

Note that ALICE VM is not working well due to those microCERNVM format changes. (The container is still fine.) Will there be a new VM (that will also work for the past data)?

I do not know, i just picked up this part of OpenData task. I do not know the requirements : what kind of VM is required? i'm not sure if microcernvm is available for everyone as AFAIR there was a need for contextualization that was done from within cern account. VirtualBox format is vendor centric (so not necessary good for the long run), KVM AFAIK is linux only ... If you can give me some specifications i can prepare a Alma9 VM with cvmfs installed that can run the ALICE software.
