This document describes the deliverable “Data and Computing Landscape Documentation System and Interview Template”. These are tools necessary for the work of Task 4.1. The interview template gives guidance for EUDAT2020 interviewers interviewing community experts and managers. The documentation system allows EUDAT2020 to coordinate its contacts with the communities. This document also describes the rationale behind it, its status, how it relates to the EUDAT2020 (internal) workflow and other EUDAT2020 information systems and how we expect the systems to evolve.
