5. A model driven development (MDD) data processing system comprising: a MDD tool stored in memory of a computer and configured to manage creation and modification of a model from a requirements document; a model query module coupled to the MDD tool, the model query module being configured to query the model tool to search a model for artifacts associated with the query and to locate in response to the query an implicit relationship between a participant and a collaboration within at least one of a requirements document for the model, the model and source code produced from the model; and, visualization logic comprising program code enabled to generate a trace link for the implicit relationship produced by the model query module and to display the trace link in a trace query diagram in the MDD tool.
