These schematic conflicts were solved in work described therein for the ELNs Chemotion and Herbie for the use case "Polymer Membrane Post-Modification". For the given use-case, we considered the relevant content of the selected ELNs which was covered in Chemotion ELN with the ELN models (input masks) for "reaction" and "sample", and in Herbie with the ELN models for "post-modification reaction" and "product". The content of the required ELN models was mapped from one ELN to the other, and conflicts were resolved by different means, e.g. the creation of new data fields (if a lack of information was detected and the need for an adaptation obvious) or converting date-time formats(details in the SI).
