This deliverable reports on an initial survey and assessment of potentially suitable software and architectures to inform further consideration during the specification of the architectural blueprint. Further, it makes use of the findings of the survey as well as of the use cases and requirements drafted in WP2. It reiterates technical requirements which will be met by two demonstrators that focus on different technical challenges. The technological survey covers authentication and authorization infrastructure (AAI), data representation and annotation, persistent storage, search and visualisation and front-end third party and in-house (provided by Fair4Fusion or EUROfusion partners) technologies. A selection of these technologies is being used by the Fair4Fusion demonstrators with the intension to evaluate them based on functional and non-functional (e.g. expertise, extensibility, etc.) criteria, with the ultimate goal to inform the blueprint architecture (D3.2 : Blueprint Architecture for a Fusion Open Data Framework with proposition of the implementation plan). This responds to the requirements elicited in WP2. These requirements are provided here as an Appendix. In WP5, the demonstrators, to the degree that is possible due to their nature and to external non-functional conditions (e.g. available resources, central decisions needed, etc.), will respond to at least these requirements designated by “MUST”.
