In a recurring revenue management system, a first unit of data and a second unit of data is received. Content is extracted from the first unit of data and the second unit of data based on one or more parameters of a predefined data object that is part of an asset data model. The extracted content is added to an instance of the predefined data object, and a reference tag with identification information for its associated content is associated with the content extracted from each of the first unit of data and the second unit of data. A duplicate data condition can be detected and resolved by applying a predefined approach to conflict resolution based on the identification information in the reference tags of the content of the first unit of data and the second unit of data.
