This report is divided in two parts. The first part provides a quick overview (like a user guide) of the final data base, built on the observation and data gathering for each physical demonstrator (Open Manufacturing) and available online since April 2021 with the following link: http://inedit-db.lf2l.fr/fr/ The second part focuses on the current state of each OMDF, it stems from the observations of the different Use Case: •§ 4- Approach to data collection (WP 4.1) •§ 5- Presentation of each Open-Manufacturing Demonstrator Facility and Cross-interpretation of results A previous conceptual task (2.2) allowed to design the DIT approach, defined the keywords and generated the requirements of DIT (digital) platform. To confront this theoretical work on DIT, we focus on the four INEDIT use cases to design a “distributed” demonstrator (in five EU countries) considering the initial state of our Open Manufacturing Demonstration Facilities. NB: An analysis of the vision of the use cases is carried out in order to identify their role in the future demonstrator and their needs to integrate a DIT process centred on the circular economy. Due to the COVID pandemic, the team in charge of this study adapted its initial approach, designed a new protocol and made interviews and online survey during this period. Each use case team gave the physical observations of their situation.
