Example of a Miro board used for identifying the overarching needs for implementing digital sensors for collecting and sampling data for EBV workflows at a European scale. Participants were asked to specify key requirements for different workflow components (data collection and sampling, data integration and modelling), interoperability aspects and IT infrastructure needs (coloured boxes in upper row). Information in the online sticky notes (coloured squares) was entered by participants and were later grouped into broader thematic topics (yellow circles).
