meeting_2022_05_10

• status of new Java framework (server-java https://github.com/hapi-server/server-java)

  • wiki describes: https://github.com/hapi-server/server-java/wiki
  • various methods for data interface exist (HapiRecordSource implementations for formatted files, spawn, classpath)
  • server will "aggregate" small reads of non-streaming service
  • server can communicate with sources to see if they must read all parameters or they read subset of parameters
  • server cleans up response, trimming extra records and validating

• review work done by Bob Weigel (https://hapi-server.org/servers-dev/#server=CAIO)

  • Code is at https://github.com/hapi-server/server-nodejs/tree/master/metadata/CAIO
  • How is this catalog populated?
  • Bob says data is not working (never did?) What is the source of data?

• How will we access data?

  • Data API? -- note it need not be streaming
  • Files -- reader for CEF files needed
  • Docker container access of data

• Timeline / goals

  • What can we accomplish before Larry's visit to Madrid
  • What should things look like after Larry's visit

Notes

Bob's server was based on an older standard that is no longer supported.

https://www.cosmos.esa.int/web/csa-guide is a guide for the TAP server.

TAP server will be used to feed data into this HAPI server. Its data responses will be CEF responses. I have a parser for CEF within Autoplot which could be extracted, and there is one within "Sparta" project at github which Hector will link to.
