WP3 – Architecture, Specification and Integration D3.3.1: Technical Specification Deliverable Lead: ASC Contributing Partners: NTUA, TALK, TIE, TPVI, UA, UOR Delivery Date: 2014-11 Dissemination Level: Public Final This deliverable represents the technical specification of the SAM platform. It defines the SAM platform from a technical point of view and shows how the components cooperate with each other in order to provide the desired functionality. It also reaches a consensus on technical decisions regarding the choice of suitable technologies/ tools for the implementation of the SAM components based on the project vision.

This document takes the deliverable D3.2.2 Function Specification as a basis to highlight and to further elaborate the design of the SAM platform into a concretely implementable solution. The methods used to achieve this are the following related activities, performed for each of the SAM components: The major design decisions were specified in order to define the context for the next steps. Technology comparison and selection was performed in order to select the most suitable technologies for the implementation of each component. The technology selection process was based on predefined criteria. Based on this process, an analysis of the relevant technologies was made, supported by a parameter evaluation, and the most suitable solution approaches were elaborated. Finally, any missing elements and implementation needs were identified. Each of the components was specified with respect to its static structure (subcomponent design) and dynamic behaviour (subcomponent collaborations design). The necessary communication protocols, interfaces and formats between the components were specified. In the deliverable, the component operations, protocols and data exchange formats are specified in order to ensure effective execution, communication and interoperability among the 19 SAM components. The detailed descriptions provided by this technical specification will underpin the further developments of the project. Therefore, this very detailed deliverable serves as the basis and guide for the entire software development in the SAM project. 5 / 274 SAM WP3 Public D3.3.1 Table of Contents 1 Introduction .................................................................................................................... 8 1.1 SAM Project Overview ........................................................................................... 8 1.2 Deliverable Purpose, Scope and Context .............................................................. 8 1.3 Document Status and Target Audience ................................................................. 9 1.4 Abbreviations and Glossary ................................................................................... 9 1.5 Document Structure ............................................................................................. 10 1.6 External Annexes and Supporting Documents .................................................... 10 2 General Description of Technical Specification ............................................................ 11 3 Technical Specification ................................................................................................ 12 3.1 Common Graphical User Interface ...................................................................... 12 3.1.1 Technology Comparison and Selection ................................................... 13 3.2 Interconnection Bus ............................................................................................. 14 3.2.1 Major Design Decisions ........................................................................... 15 3.2.2 Technology Comparison and Selection ................................................... 16 3.2.3 Technical Component Specification ........................................................ 19 3.2.4 Specification of Interfaces, Protocols and Formats .................................. 19 3.2.5 Summary ................................................................................................. 36 3.3 Semantic Services ............................................................................................... 37 3.3.1 Major Design Decisions ........................................................................... 37 3.3.2 Technology Comparison and Selection ................................................... 38 3.3.3 Technical Component Specification ........................................................ 48 3.3.4 Specification of Interfaces, Protocols and Formats .................................. 48 3.3.5 Summary ................................................................................................. 63 3.4 Social Components ............................................................................................. 64 3.4.1 Major Design Decisions ........................................................................... 64 3.4.2 Technology Comparison and Selection ................................................... 65 3.4.3 Technical Component Specification ........................................................ 67 3.4.4 Specification of Interfaces, Protocols and Formats .................................. 68 3.4.5 Summary ................................................................................................. 86 3.5 Syndicator............................................................................................................ 86 3.5.1 Data API Services.................................................................................... 87 3.5.2 Multi-Device Representation .................................................................... 95 3.6 Content Gateways ............................................................................................. 100 3.6.1 Major Design Decisions ......................................................................... 101 3.6.2 Technology Comparison and Selection ................................................. 102 3.6.3 Technical Component Specification ...................................................... 106 3.6.4 Specification of Interfaces, Protocols and Formats ................................ 107 3.6.5 Summary ............................................................................................... 117 3.7 Context Control .................................................................................................. 117 3.7.1 Major Design Decisions ......................................................................... 118 3.7.2 Technology Comparison and Selection ................................................. 119 3.7.3 Technical Component Specification ...................................................... 120 3.7.4 Specification of Interfaces, Protocols and Formats ................................ 121 3.7.5 Summary ..............................................................................................
