Information Modeling for Single Sourcing 
Single sourcing involves identifying all information requirements up front, then developing them from a single source. Information is broken down into elements, which are reused wherever they are required. Information models identify to writers all the required elements, how to structure them, and how to reuse them. This paper describes the process of information modeling.
