An important part of the ODM system is the Harmonization Engine, which is the module responsible for integrating and reconciling the raw metadata collected from the monitored catalogues into an internal representation. This allows for further processing and analysis, in particular for the calculation of the various metrics employed for monitoring. Some first steps of this process were undertaken during the first project period of the project (see Deliverable D3.3). During the second project period, the harmonization process has been extended to a fully functional component with multiple levels of mappings and different processing handlers. Additional components were also implemented to remove existing duplicate metadata.

Below you can find details on the ODM Harmonization Engine.
