Cognos software built-in namespace

[esanray]

I am little bit confuse in Namespace. Can any  body explain me the  different between the Framework manager Namespace and  IBM® Cognos software built-in namespace.

[MFGF]

One is a metadata namespace, used as a container when modelling (and used in the unique naming strategy of items within it) and the other is a security namespace used to provide customisable groups and roles within the Cognos environment.

MF.
