BW meta data repositary - toolset

Hi,

I would like to suggest a toolset for our users to search on the various KPI's, Formulas, InfoObjects available in BW currently. This should be an easy search - without much need of any training.

Can you suggest any toolset? Can Information Steward be used? Has anyone used it before for creating such a meta data repository.

Please suggest.

Thanks,

Purbali
