An embodiment includes locating source data associated with a data replication request, and identifying a property of a data value of the source data using a reflection process. The embodiment determines a meta-type for the data value using an automaton that identifies a matching extent class from among an indexed set of extent classes that define respective accessors that are invoked to locate an extent class that corresponds with the property of the data value. The embodiment generates target data having the data value and a data type that corresponds with the matching extent class. The embodiment generates a changes feed that includes the generated target data, evaluates data in the changes feed to determine whether a specified condition has been satisfied and, if so, generates a trigger signal that initiates an event, where the trigger signal comprising information that satisfied the specified condition.
