After setting up the general mapping framework with steps 1-3, the Sync Model Manager (Figure ) of ELNdataBridge allows defining the main properties and pairing settings (Figure ) by either the creation of new synchronisation models or the management of existing ones. Each sync model requires a unique identifier, which is a human-readable name, and the names of the two ELN models (input masks) that need to be synchronised (Figure ). Additionally, it's crucial to set the keys for both ELN models. The system uses these keys to identify and match pairs to ensure the accuracy of the synchronisation process.
