This chapter presents the Metamodel and some considerations about how to use it.

Basically, a tracemodel is a set of Reference (textual or model) and a set of Trace. A Trace can be decorated by a Message that gives information about who and why the trace was generated.

	Note
	You choose the level of granurarilty of your traces and if they are optimized or not by optimized we mean garanting that there is one and only one ModelReference for a given Object. This optimization can be done while building the trace or in a post processing.
