Abstract: An apparatus and method are disclosed for defining a workflow. An apparatus that incorporates teachings of the present disclosure may include, for example, a computing device can have a controller programmed to organize one or more active objects selected from a content source according to a plurality of operational paradigms to construct a workflow, and present a graphical user interface (GUI) comprising a hierarchical structure of the workflow. Additional embodiments are disclosed.

Abstract: A computing device comprises a memory to store a first version of an extensible Markup Language (XML) message, a receiver to receive a second version of the XML message, a processor and a display interface. The display interface provides a user interface having a first control, a second control and a third control. The first control is to cause the processor to merge the second version with the first version to produce a third version of the XML message. The second control is to cause the processor to replace in the memory the first version with the second version of the XML message. The third control is to cause the processor to reject the second version of the XML message.
