WP3 facilitates the work of WP2, 4 and 5 by identifying and providing access to relevant data sources for answering the research questions defined within ROADMAP. WP3 has developed a preliminary workflow to achieve this. After approval by the WP leads, ROADMAP researchers are required to fill in a specifically developed scientific research question form. This will be send to WP3, which then triggers the search for relevant data in all ROADMAP partner platforms. If the data are already uploaded to one of the platforms, data access can be provided fast, conditional on the approval of the data owners. Researchers can also identify data that are not yet included in one of the partner platforms. In this case, the data owner will be approached and asked for participation in the study.
