This document contains the Data Management Plan (DMP) of PathOS on M6 of the project. It is a living document that was updated on M18 of the project (DMP D3.5 is avalible here https://zenodo.org/doi/10.5281/zenodo.11049556). It has been created using the ARGOS service (https://argos.openaire.eu) an online tool for creating, managing and sharing DMPs and linking them with the research artifacts they correspond to. In the DMP, we describe the input (re-used) and output (created) datasets that will be used in the technical work of PathOS, following the principles of Open (whenever possible) and FAIR as outlined in the Grant Agreement.* * The numbering of the questions skips in order to allow the updating of the DMP in the future (i.e. filling out questions for which the information is currently missing) via the Argos service. * This project deliverable is currently pending approval by the EC.
