A method for managing semantic and syntactic metadata. The method begins with receiving heterogeneous data from either a machine or a human. Next, the method captures the semantic metadata corresponding to the received heterogeneous data by means of a semantic template. Next, the method captures the syntactic metadata corresponding to the received heterogeneous data by means of a syntactic template. After capturing the semantic and syntactic metadata, the method logically links the received heterogeneous data with the captured semantic and syntactic metadata. Finally, the method stores the received heterogeneous data in a repository.
