This deliverable reports on the deployment of PID Graph functionality in FREYA’s pilot applications. Initial steps for building the PID Graph include advancing the implementation of person-article-data linking, further establishing software citation and publication workflows, and integrating mature PID types into the different disciplinary systems. This first report for Work Package 4 presents considerations and implementations stemming from the first year of work carried out by the pilot applications and sets the scene for the future integration of new and emerging PID types.
