CERN is, since the end of 2014, serving some fraction of the colossal amount of captured data about particle collision in LHC (with detectors like CMS, ATLAS, ALICE) - summing up to 60,000,000 GB.

Through the help of a small Python crawler, I've compiled an index of all CMS-detector primary datasets (all .root files totaling cca. 27,4TB). Also index of indexes. Other detector indexes of datasets + derivative datasets to come :)

• CMS
  • Primary datasets from 2010 runs (27,4TB)
    • Scrap data from CERN's OpenData (via cmspull.py)
    • Compile index of all primary dataset files (.root)
    • Somehow get those 28TB into IPFS (maybe in cooperation w/ CERN? - than all steps are unnecessary)
• ATLAS
• ALICE
• LHCb

To use all that data, a special environment is required - normally CERN's OpenData is recommending the use of their CernVM, which is basically Scientific Linux + ROOT, a data analysis framework (therefore the .root files). Without ROOT, this historical milestones cannot be used as computable data directly - so the tool must also be, as the collision data, preserved/archived. There's also a mirror right here at Github.

Oh, and thanks for the amazing project!
