ACCORDION D2.1 - User requirements (I)

This deliverable provides a set of requirements of the ACCORDION project. This is a first iteration of the requirements collection process. This document is a fundamental pillar for the development of the whole architecture of the ACCORDION framework and provides requirements from both functional and non- functional sides, that are essential for the design and development of the ACCORDION framework. User requirements are listed in the table that will be the basis for further work. This document can be also considered as a checklist of the items that the consortium has to monitor, implement and evaluate during the project lifetime. In order to improve the quality of the presentation and thus ease the readability of the document, this deliverable summarizes the project's use cases (general summary and approach) and the ACCORDION platform requirements. The requirements are organized in three main categories: o General-purpose requirements: provided by the use case owners, are the key features of the NextGen applications shared by all the three use cases. o Use case related requirements: extracted by analysing the needs of the NextGen applications, filtered through technical and business-related criteria. o Technical/Scientific requirements: extracted from the use case related requirements and from the research goals of the project.
