Management Summary This document provides a detailed description of the implementation specifications for the involved disruptive technologies. It specifies, in particular, the interaction between the different components based on the agreed integration paradigms which allow a modular development of the components with clear interfaces. In an analysis of the requirements from the proposal and deliverable D1.1, the combination of server centric components and distributed ledger based components was identified as a challenge. Following a developer meeting, the developer teams worked with the pilot sites to collect the missing information on requirements. The chapter “System architecture and technological integration” describes the above requirement elicitation process and the integration plan. The modularized design of the backbones enables the possibility to run it as a distributed system that is perceived/interfaced as one virtual application. To show the flexibility of the design, the chapter exemplifies some bilateral integration and the possibility of including more in the process. The chapters on the individual platform components describe the theoretical background as well as considerations and decisions when it comes to architecture, design, configuration, operational stability and scalability as part of the CO3 platform. These chapters also contain the respective database schemes, dependency specifications and license information to the extend they are already available. The chapter on the system as a whole summarises the system architecture, elaborates on the foreseen platform instances and sustainability beyond the scope of the project. 5 CO3 Project D2.1 2. System architecture and technological integration 2.1 Requirements and Integration Framework Analysis of requirements from the proposal and D1.1 in regard of relevance for integration This section reports about the analysis of requirements with relevance in regard of the overall integration process, i.e. with relevance for the overall technical structure, including interface interconnections, data transmission, transformation, storage and processing, but also the unified user management and the OnToMap data hub. Requirements without relevance for the integration process as well as requirements which require additional bilateral integration between certain components are expected to be analyzed and documented by the corresponding tasks. The requirements and functional description of the envisioned platform are scattered along with the two parts of annex 1 of the grant agreement: ● Part A of annex 1 which outlines the specific work which has to be carried out and regulates which partner is responsible for the execution of development work. ● Part B of annex 1 which describes a vision of what the platform users should be able to do by describing features and providing user stories in the context of the commons. Most implementation relevant requirements in annex 1 have been found in the following sections: ● the objectives of CO3 (in part A) ● the objectives of WP2 (in part A) ● the task descriptions of WP2 (in part A) ● section B1.1.3 (in part B) Additionally, the report D1.1 is available and provides further relevant input for the integration. Even while no coherent description of the overall functionality is given in a single place yet, the pieces have been connected to a conclusive picture which is described in the following sections. Evaluation of risks and benefits for 5 disruptive technologies CO3 is about the evaluation of risks and benefits of 5 disruptive technologies:1 ● Distributed Ledger Technology represented by a Blockchain based general exchange system where goods and skills are shared. ● Map-based Citizen Networks represented by the FirstLife local civic social network with an interactive map: it will allow crowdmapping of information by citizens that can coordinate with each other and the PA in the management of urban commons.
