Who is using Research Objects?

Structure of CWL run Research Object:

 

  • data: content-adressable by sha256 hash
  • workflow: input object (json file) with relativised paths, packed.cwl
    executable workflow containing the workflow specification and tool specifications with relativised paths to re-run inside an RO.
  • snapshot: This directory contains copies of the original workflow and tool specifications files as-is (warning: might contain absolute paths or be host-specific).
  • metadata: provenance about the workflow run, its data products and manifest for this Research Object.
