4. Our “connection” Meteorology is key to aviation
It always has been and will be even more so
The future of Trajectory Based Operations (TBO) is about increased predictability
Aviation on the move towards making the air transport network smarter, and according the SES ATM Masterplan also from a multi-modal point of view
System Wide Information Management (SWIM) aiming at digital information exchange in support of improved decision making and collaboration.

5. Similar “nuts to be cracked”?
Although probably differences in scale and maturity levels.
People, applications and processes become more and more connected…
They don’t seem ready yet …
Great, we’re getting a company smartphone!…

6. But what is SWIM? Overloaded consumer in a pool of information.
Forward looking provider
and SWIM adept.

7. Think interfaces that exchange information.
SWIM is about services.
Think interfaces that exchange information.

8. SWIM is about interoperable information services.

11. SWIM at ICAO level
SWIM Definition from ICAO Manual on SWIM Concept (Doc 10039) and European ATM Masterplan:
SWIM consists of standards, infrastructure and governance enabling the management of ATM information and its exchange between qualified parties via interoperable services

12. Key structural SWIM components.
Information
Information is encapsulated in networked services
Information Service
Layer put in place between the provider and the consumer
Technical Infrastructure
Enabler of information exchanges (e.g. messaging, security, …)

13. There is no magic in SWIM .

14. SWIM is about standards.
Think specifications agreed by SWIM participants.

15. Some steps that lead to where we are

16. From Single European Sky Research to a unifying Aviation in a digital and seamless sense

17. SWIM, the enabler of the seamless digital future.

21. EUROCONTROL Specification SWIM Service Description
Provides requirements for describing information services.
For a service consumer to discover a service, consider using a service, or implement a service consuming client
Defines the minimum set of elements a service description has to contain to make it searchable and useful.

22. EUROCONTROL Specification SWIM Information Definition
Provides requirements for information exchange definitions conform the semantics of the ATM Information Reference Model (AIRM)
Contributes to the semantic interoperability of information.

23. EUROCONTROL Specification SWIM Technical Infrastructure Yellow Profile
Provides requirements for IT infrastructure capabilities and interfaces:
Service interface bindings (e.g. protocols)
Network interface bindings
Facilitates the reliable, secure and efficient exchange of information. Contributes to technical interoperability.

25. But which information services?
PCP IR requirements are “performance based”
No technical details about how a specific information service is to be implemented
Balance between what is required (e.g. PCP IR) and a good innovative idea
top-down versus bottom-up
Before say 1995 no one could think (“i.e. require”) digital maps on a handheld device that could show location and also make calls…
How to ensure that we have an information service that is a good member of the family?
Ensuring re-use

26. SWIM is about the right information services.
Thinking collaboratively.

27. Service Orientation Process
Key aspect of SOA
No singular right way
Top-Down: architecture driven
Bottom-up: productivity driven
activities to implement the service in a target environment and technology context
activities involved in documenting
operational context and business need
information exchange requirements
non-functional requirements
activities involved in expressing what the service does and how it works
activities where the information service instance is made available for use in operation

28. SWIM is about formalisation of information and knowledge.
Think model driven .

29. The right information? The ATM SWIM toolbox includes a “Swiss-knife”
The ATM Information Reference Model (AIRM)
The reference for information exchanged in SWIM

30. AIRM (1) Textual descriptions e.g. ICAO Annexes Contextual Model
general elements such as ATM Business Terms and publications which provide the scope
Textual descriptions e.g. ICAO Annexes
Conceptual Model
descriptions on a level that are generally understandable to a business user
data models
Logical Model
detailed and structured elements needed to develop technical building blocks

31. Unbundling ATM information to better re-bundle it.

Cross domain semantic reference
Not bound to a specific solution
Reference for architecting information services
Tool for ensuring semantic alignment in a service oriented environment
Covers iWXXM 1.2 content future work to look into iWXXM3.0

32. Open GeoSpatial Consortium
ISO TC211 - ISO abstract specifications
AIRM refers to key foundational standards
e.g. ISO for metadata and ISO for geospatial data
foundational within ATM but also for Meteorology
OGC Implementation specifications used in SWIM contexts
E.g. Geography Markup Language (GML)
OGC Web Services
In ATM currently FIXM does not align at GML level, but does for example at ISO level
The AIRM “Swiss-knife” keeps it together

33. Evolution of information exchange
From industry specific messaging to vendor neutral standards
Towards connected processes and applications and only a few common components in the middle.
PKI
SWIM Services Registry

34. One step beyond
2018 – the breakthrough of mainstream graph database technologies
Everybody can become “the next one”
Use cases such as:
Lineage metadata
Infrastructure management
Re-birth of the semantic web as “connected data”
Silos remover
Knowledge graphs
Filtering information
Starting to think about possibilities
