Abstract: A method, system and computer program product include a data processing system that comprises a set of data processing modules, the set of data processing modules adapted to assign at least one tag to each data item included in a first set of data items, the first set of data items corresponding to a first application, the first application running on the data processing system. The set of data processing modules are adapted to also assign at least one tag to each data item included in a second set of data items, the second set of data items corresponding to a second application, the second application running on a remote data processing system. The set of data processing modules are further adapted to identify a set of related data items based on corresponding assigned tags, the set of related data items including at least one data item included in the first set of data items and at least one data item included in the second set of data items.
