2. AIOTI WG3 IoT Standardisation - Release 1
Objectives
Provide an initial proposal for a high-level architecture to serve as basis of the discussion within WG3 and across AIOTI WGs
This proposal is aiming to be neutral but its development did consider existing SDOs work
An important objective is to allow any instantiation pertaining to LSP deployments
AIOTI WG3 IoT Standardisation - Release 1

3. Approach using ISO/IEC/IEEE 42010
Follow ISO/IEC/IEEE 42010
Define models for relevant architecture views and don’t mix everything in one model
Focus on what makes IoT special/valuable
Thing in centre of value creation
IoT is not just things + connectivity  infrastructure services
AIOTI WG3 IoT Standardisation - Release 1

4. Principles of ISO/IEC/IEEE 42010
An architecture description expresses an architecture of a system of interest
An architecture description contains of multiple views
Each view adheres to a viewpoint
Each view consists of models
ISO/IEC/IEEE specifies minimal requirements for:
architecture descriptions
architecture frameworks
architecture description languages
architecture viewpoints
AIOTI WG3 IoT Standardisation - Release 1

5. AIOTI WG3 IoT Standardisation - Release 1
WG3 HLA
Is consistent with but does not provide a complete architectural description
Provides partial Domain and Functional Models
The Domain Model describes entities in the domain and the relationships between them
The Functional Model describes operations, interfaces and interactions within the domain
Specific use-cases are shown to illustrate the functional model and to highlight privacy issues
The relationship to other IoT architectures is also highlighted

24. Architecture and Platforms
Slide 25 shows one important artefact: Platforms
Slide 25 also shows that interactions between platforms might be needed
Application A calls a FIWARE API for a capability that is provided by a universAAL platform: examples include federated identities and authentication, data brokers, etc.
Potential gap?
