There is a trove of data in the yumdb (still present in older dnf-based installations) that we should collect. See http://yum.baseurl.org/wiki/YumDB.html
On newer dnf some similar data is in a sqlite db https://fedoraproject.org/wiki/Changes/Unified_database_for_DNF
Ideally this would be data that are combined with the main RPM data
