Data Lineage

Data Lineage,
Basically where did my presentation layer object come from (kinda)
See the link below which give some concepts:

What I'm asking people is how they have catered for it in BI Projects?

My first pass (Using OBIEE) would be to use the administrative tool to output the repository metadata and present this information at the presentation layer some how.

Any thoughts, ideas, methods or concepts would be appreciated.

Thanks

Ciaran.
