Résumé
The diffusion of knowledge, extracted from the Knomana knowledge base (Silvie et al., 2021) or inferred using Knomana, requires to develop a specific application for each type of final user (e.g. researcher vs. farmer). This involves to develop a family of similar applications, which can be done thanks to the paradigm of software product line. A challenge is to identify, analyze and structure the functionalities required by each user before the development of such applications. The considered solution is to analyze the variability of software systems similar to the ones we plane to develop.
