TaskNotes
Artefacts to describe services

Service Descriptions
  • no updates
Support
FAQ
  • Questions to be answered (send suggestions to the group):
    • How do I describe a service that uses GraphQL?
      • Some example of services that use GraphQL were presented. This highlighted some key points.
        • The schema is self documenting (the same goal as Open API).
        • The service uses HTTP - a query that embeds elements from the schema is sent to the server, JSON responses are returned.
        • The schema can be based on the semantics of AIXM/AIRM.
        • It is possible to query, post and subscribe using GraphQL.
        • In general, GraphQL is better suited for mobile and light-weight applications. The current tests have not fosused on system-to-system exchanges.
        • The approach seems acceptable under the SWIM TI Yellow Profile.
      • An answer will be drafted and made available to the group. (See Documenting the use of standardised implementations for inspiration on the content of the answer.)
Service Metadata Schema
  • Service Discovery Service
    • ICAO Job Card on registry interoperability has started work. It recognises three levels of registry interaction:

      • interoperable - queries are sent between registries based on agreed metadata; interconnected; and integrated

    • The focus is on the interoperable level for now.

  • Version 1.0.0 of the service description schema is available for testing. Some group members have implemented it in their systems.

    • It will be made official once Registry CCB confirms it.

SWIM service ecosystem
Service Design Activities
  • We will inform IMT on 18-19 April of the intention to look more at this.
  • Added guidance on the use of CodeApplicationMessageExchangePatternType e.g. PUBLISH_SUBSCRIBE for services built around AMQP 1.0.
Service Categories - Service Type
  • A meeting focusing on FF-ICE services and AMQP will take place on Monday 3rd April. Invitations will be sent soon.
Service Portfolio
  • We will inform IMT on 18-19 April of the intention to look more at this.
  • The page was updated with some new sources identified by the group.

Registry

  • There will be a Registry CCB in late April.

ICAO Information Management Panel (IMP)

  • State Letter including PANS-IM has been circulated. Highlights:
    • The AIRM is explicitly mentioned. If you don’t use an already mapped XM, you will need to perform your own semantic correspondence.
    • The service chapter concentrated on the information service overview. This can be seen as a subset of the service description for describing running services.
    • The technical infrastructure yellow profile is mentioned in a note in the technical infrastructure section.

Next meetings

Meeting schedule is maintained at SSCONE-SITCOM Meetings. 

Next progress meeting is 24 April 2023.
