Agenda 

Welcome

Objectives of this meeting are:

• work on tasks

Update on tasks

Task list

The updated task list is at SSCONE-SITCOM Tasks.

Completed tasks

• tbd

Ongoing tasks

• Maintain supporting material

  • SWIM Service Description Handbook v2.0

    • The comments received by the 24th June were reviewed. See . Some resolutions have lead to extra work and the supporting material will be updated once the resolution is known.

    • Some actions in Maintain supporting material were can be marked as completed.

    • It was agreed to remove the "WIP" status and enter maintenance phase.

    • The focus should now be on standardised implementations as most remaining actions/comments/best practices depend on it.

  • Service Metadata Schema

    • See: https://github.com/eurocontrol-swim/service-metadata-schema/blob/sds-upgrade/description/SRV-DESC_SCHEMA.json

    • The comments received by the 24th June were reviewed. See . Some resolutions have lead to extra work and the supporting material will be updated once the resolution is known.

    • A new structure has been put in place for the github repository and the schemas have been renamed.

    • At the moment:

      • service description schema is finished

      • service definition schema will start - it will be a separate schema

      • service candidate scheme will be derived from the service description schema by relaxing the number of required fields. It will be a separate schema.

    • The schemas will be separate but the structures are aligned where feasible.

    • Validation of files against the schemas can be done using various tools. No specific validation suite is foreseen.

  • Best practices to harmonise content of service description fields.

    • Some rows have been marked as "Review and accept?". The group is asked to review these by the next meeting to ensure the proposed solution is accepted.

• SWIM service ecosystem

  • Documenting the use of standardised implementations.

    • Start work on standardised implementations based on the comments and input already received.

    • The skeleton material will be available by the next meeting. The group will be informed as it is created.

  • Service Categories

    • The group is asked to review the mature schemes by the next meeting. If accepted, they will be published on the reference site:

      • CodeDocumentType

      • CodeAccessAndUseConditionType

      • CodePrimitiveMessageExchangePatternType

      • CodeServiceInterfaceBindingType

      • CodeServiceValidationType

      • quality of service

      • security mechanisms

      • information exchange models

      • data formats (if needed in the end)

    • Also:

      • add EXPERIMENTAL to https://reference.swim.aero/information-services/service-categories/CodeLifeCycleStageType.html

    • A new category (Service Categories - Using the Service Type) has been added based on service type. This grew out of discussions in A3SG. It is used as a way to identify similarities in the services being discussed. We should discuss this at the next meeting. It overlaps with the discussion on standardised implementations.

    • We were request to move items out of the Service Metadata Schema to the reference.swim.aero. These were:

      • DocumentType,  Service Interface Bindings, CodeServiceValidationType, primitive MEPs, AccessAndUseConditionsType

  • Service definition template

    • This has been added. It is draft material to help in the various *3SGs. We should discuss this at the next meeting.

Any other business

• none
