In this section, we aim to provide a brief overview of the most important requirements for content, functionalities, and business goals.

Essential Content Requirements

• Provide software that acts as an In-house Consent Administrator (ICA) and Metered Data Administrator (MDA) for in-house measured data, runnable as far as possible on existing hardware already available in-house, e.g., home automation systems, network attached storage systems, minicomputers, SoCs. Initially, the focus will be on making available data provided through standardized interfaces as mandated by Article 20(a) of Directive (EU) 2019/944, and will be stretched to other data sources (e.g., sub-meter data) later down the road. Developments in legislative activities (e.g., network codes and implementing acts on interoperability and distributed flexibility) will be taken into account when setting priorities.
• Provide the means to integrate near real-time data from AIIDA to the EDDIE Framework. To make these data streams even “detectable” is a design challenge that needs intensive architectural activities considering aspects like security, usability, and performance amongst others. The goal here is to optimize the user experience within the EDDIE/AIIDA service landscape, which implies that AIIDA will also have consent management for the customer.
• Account for observability and manageability for the customers. Customers should always and easily be aware of how and when they share their data (and also by whom). Seamless integration in existing application infrastructure (e.g., smart home apps as far as possible) is vital for the acceptance of the solution.

Essential Functional Requirements

• Decentralized: The EDDIE Framework is installable on any computer or cloud environment under the full control of the actor using it. There is no need for a central instance or a Pan-European Data Hub. The decentralized approach also guarantees a maximum degree of scalability, flexibility and resilience.
• Open-source: The EDDIE Framework and AIIDA can be freely downloaded, forked and changed, without any fees or licensing constraints. After the project lifecycle, the EDDIE consortium will transfer the management and maintenance to a relevant body. That point in time will also coincide nicely with European developments in the field of interoperability, and the decision as to which organization to hand over will respect these.
• Far-reaching: The EDDIE Framework achieves high compatibility with regional data-sharing infrastructures within Europe (potentially, and beyond Europe). Notably, EDDIE is for a good share initiated and driven by European data-sharing infrastructure operators who are participants in the consortium. This involvement means that we have these organizations onboard which need to make the data available directly in the project and on a broad geographical basis.
• Not-for-profit: Apart from the innovation and know-how generated in the work on EDDIE, none of the consortium partners is expecting any direct returns or profit out of the generated software and deliverables. All participants have expertise in different domains or geographical areas, which they want to contribute to a greater – common – profit and a reliable infrastructure for an enhanced market.

Essential Business Requirements

1. Provide the EDDIE Framework as a dependable, scalable and extensible framework that is open source and free to use and change. The EDDIE Framework will be installable in the domain of eligible parties with the need for access to energy data on a customer consent basis. There will be no need for additional centralized intermediaries. This main outcome is aligned with European interoperability, digitalization and data-related legislation, and also provides means to feed back into these initiatives, leading in turn to better-informed decision-making.
2. Provide AIIDA as an Administrative Interface for In-house Data Access, easily integrable in domestic software systems like smart home solutions or edge devices, making use of existing or additional hardware to be easily deployed in customer houses. Provide customers with a new solution to make available data streams from the standardized near real-time interface on the smart meter (and potentially from a variety of in-house sensors). Allow customers to share their data with services using the EDDIE Framework, on a secure, clean and manageable consent basis.
3. Provide extensive scientific assessment and share real-world experience on various aspects of data-sharing, from a social, economic and technological point of view. The academic institutions within the EDDIE consortium will care about this scientific assessment from energy and behavioral economics, regulatory and legislative, and system safety and security aspects. For all prototypes, we put a focus on human-centered design and user research to support the social acceptance of new energy technologies and increase the participation of consumers in energy.
4. Provide the EDDIE Data Services Market Place as a web-based and/or mobile solution, which allows customers to easily access applications based on the EDDIE Framework, learn about the services offered, use services of interest and participate in the data-sharing community. Customers must and will always retain full control over their private data at all times. The EDDIE Data Services Market Place will also contain all demonstrated prototypes.
