AIOTI WG3 IoT Standardisation - Release 1 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 2

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 3

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 42010 specifies minimal requirements for:

• architecture descriptions• architecture frameworks• architecture description languages• architecture viewpoints

AIOTI WG3 IoT Standardisation - Release 1 4

WG3 HLA• Is consistent with 42010 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

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?
