A detailed configuration of the sync model for the ELN mapping can be set in forms that guide the user through the required information, supporting a customizable synchronisation process. Most of the fields in the user-friendly form rely on a click-and-select mechanism by dropdowns or a selection from the JSON representation of the objects (input fields) displayed below the form. The sync model was designed to also support complex synchronisation processes by including submodel synchronisation (details see supporting information). That allows, e.g., for the synchronisation of all related data of a selected molecule of a reaction across the different ELNs while other materials used within the same reaction can be ignored.
