Deliverable report D7.4 (update 1) of the EU Horizon 2020 Project OPTAIN (Grant agreement No. 862756). D7.4 presents the overall method used to set the LE development strategy. The vision was elaborated during the first year of the OPTAIN project and sets the forthcoming steps for the second and third years of the project. This document is the first update of the report. Summary The Learning Environment (LE) is an online platform that is being developed to help building capacity and disseminate OPTAIN methodologies and results and to convey the knowledge co-created by OPTAIN consortium towards NSWRM stakeholders and beyond. The strategy development for the LE is an iterative process that has started at the beginning of the project (September 2020). Two updates of the strategy are planned over the course of the project. The first version of deliverable D7.4 was released at month 12 (August 2021). It corresponds to part 1 of the deliverable. Among other things on the method, targeted audiences, planning, etc., it presents the consolidated vision of the LE. The vision was based on the foreseen LE described in the Description of Activities and the expectations of the partners gathered via interviews. As a result, the frame of the LE was designed. The first update of the deliverable D7.4 was submitted in October 2023 (this report). It corresponds to part 2 of this document. The starting point of the first update is the LE frame, which guided the development of the first mock-up and then the development the first on-line version. The overall development benefited from regular exchanges with the partners, case studies stakeholders through the MARG as well as with external stakeholders through interviews made for deliverable D7.5 to set OPTAIN training analysis. Part 2 starts by highlighting the conceptual development of the LE that took place from August 2021 to October 2023. Then, it focusses on the technical development, which ended up on the first online version, presented during the OPTAIN Summer School (Prague, July 2023) and the OPTAIN General Assembly (Italy, September 2023). Part 2 also reminds the key discussions that took place on the indicators used by the CS leaders to describe their NSWRM.
