Discovery Webinar to Help Infusion?

  • To help new infusion cases of Discovery services.

    • intended mainly for the techies.
    • could even show again at ESIP.
  • Contribute slide content

    • Ruth at beginning stages of using DataCasting to feed aggregator for web portal

Follow up on DCP-1

  • Interoperability
    • Want to make sure that both service and client implementations adhere to the specification to ensure interoperability.
  • Any plans for existing and new implementations of Discovery service providers to follow the DCP-1 specification?

Next DCP Ideas

  • Which ideas to formalize next?
  • Need motivators first to draft up specification documents and then handoff to facilitator for going through the DCP process.
  • New incubator ideas
    • Ruth wants to propose OpenSearch for Services. Essentially using OpenSearch as ServiceCasting.
      • Using same OpenSearch Request interface for DataCasting and ServiceCasting.
      • need to post information on this on wiki.
    • Hook wants to propose a JSON response format for the Discovery specs
      • should help to (1) increase development productivity and (2) increase efficiency of response--especially for non-pagination responses
  • Some existing ideas

Product & Services Testbed

  • What use(s) the Discovery cluster might be able to think of proposing. See Testbed.
  • If we have applications that are portable, can put on the testbed.
    • e.g. drop down portable OpenSearch server
  • Want to test server implementation on the testbed.
  • Want to test clients.
  • Products and Services proposal for test bed activities. some funding available.
    • Discovery cluster could also contribute to the testbed proposal. Hook to write up addition and email Ken.
  • testbed could also be used to test out new reference implementations of DCP specifications.
    • allows for clients to test interoperability and compliance.

Next telecons
