16:00 → 17:00 Discussion

• Klas, Aard, Dave, Enrique, Hugh, James, Maisam, Manuel, Nuria, Stefano, Susana, Thomas
• Manuel — how to register BinderHub in ESAP.
• Dave put together a draft of metadata for “executable artefacts”; hoping for feedback from OSSR.
  • Currently using JSON schema.
  • Will be presented at the IVOA InterOp at the end of April.
  • https://git.astron.nl/astron-sdc/escape-wp5/esap-general/-/issues/97
  • Enrique is looking at it, and will circulate to WP3.
• Klaas — Minimum requirements for staging data.
  • Adding a lot of data, don't require login, don't run extra commands.
  • Dave: heading in the same direction as the metadata ideas.
  • By using plugins, it's possible to delegate permissions to the infrastructure but only when the infrastructure actually understands it.
  • Stefano
    • Is the plugin a software component inside a container?
    • Is it mandatory to download data to compute?
      • Not necessarily; it might already be colocated.
      • Storage plugin simply makes the data available through a URL; it does not mount data itself.
      • The user does not have access to the ESAP worker.
    • How does the user provide their credentials to the ESAP worker?
  • John: what are the next steps?
    • Klaas: create an issue for D1.2 to capture this diagram.
    • Make a simple example based on a simple Jupyter notebook; build an MVP.
    • This builds on the basic ESAP async system; that is only a couple of days out.
• Next week, Klaas will do a demo of async-ESAP.
