Abstract: PowderLib is a new software tool proposed to help with the dissemination of scientific research in the field of production and characterization of vegetal powders with an open science approach. PowderLib is composed of two software components: a knowledge book (LDC) and the Capex system. An LDC is an electronic portal with hypermedia contents and has the objective of spreading knowledge of a specific industry or discipline. Capex is a generic decision support system that helps to choose the right technological action in order to reach a certain product quality or to solve a default in a transformation process. Nowadays innovation in the area of vegetal powders is increasing, with many applications of interest (eg. bioethanol or biomaterials). The process of obtaining such powders (drying, milling, and separation) can present problems, the information in PowderLib will help to solve these issues. During this internship, the objective was to create a prototype of PowderLib. In order to acquire the necessary skills for this, a series of training on milling procedures, powder characterization, and informatics software were performed. Then the content of PowderLib was created by performing interviews with targeted users, defining use-cases, creating conceptual maps, knowledge sheets, and designing decision trees with domain experts to solve production problems. The final result was the creation and assessment of a prototype of PowderLib which was evaluated by 3 use-cases
