This deliverable set-up the foundations for the technical developments of the Möbius tools. It gathered the different background technologies, tools, libraries and standards that are relevant for the developments. The expected technology outcomes of the project were afterwards presented: the Prosumer Intelligence Toolkit, the Möbius Creator’s Toolkit and the Möbius Player. The user requirements gathered were then summarised and analysed. Requirements that were out of scope were identified and for all the others it was the implementation implications were distilled based on three main aspects: backend, frontend and storage. Based on this, for each of the Möbius tools the functional and system requirements were specified. In total 44 requirements were identified for the backend components, 40 requirements were identified for the user interfaces and 28 requirements were identified for the storage. All these requirements were prioritised. Additionally, 19 further requirements were extracted for the Möbius container format. Architectural diagrams for each of the Möbius envisioned outcomes were presented as well as API descriptions for the data models and related methods. Finally, the approach for user feedback and integration process was presented. This deliverable represents the main outcome of Task 2.3 “Architecture, logic and interfaces” and it contains the guidelines to assist the design of software integrations and tools, including prioritized requirements based on the user feedback. It also contains the outcome of surveyed tools and technologies relevant for Möbius which was carried out in T2.1 “User-driven innovation framework for enriched publishing”.
