Micheal,
Yes. CMS database is encrypted to avoid the direct SQL query fired against it from external non- businessobjects application. That is the reason why Query builder is provided to query against the CMS repository. Unfortunately there is no provision to get these information directly in any of the BusinessObjects reporting solutions.
To achieve the same you should develop your own custom SDK utility which extracts the information from repository and pushes into your custom database table on top which you can create your own set of metadata reports.
Refer the link below to know more about SDK API's along with sample codes.

Dont hesitate to revert back in case of any query.
