A data object can be received at a first time at a first inbound interface of a first software component from a second software component. The first inbound interface can be configured to map a first feature of the data object to at least one first internal data structure of the first software component but not configured to map a second data feature of the data object to any corresponding internal data structure of the first software component. Characteristic information of the second data feature can be stored in a generic data container added to the internal data structure. The characteristic information can include a value of the second data feature and metadata describing an identifier of the second data feature. A reconstructed data object can be formed at a second time subsequent to the first time. Related methods, systems, and articles of manufacture are disclosed.
