ContentExplorer can not only manage movies and licenses, but also persons and companies. The term "persons" in ContentExplorer defines all (dead and alive) natural persons, the term "companies" defines all corporate entities. Persons like actors, directors, singers, speakers are most of the times linked to content, like programs, series, trailers and advertisements. Companies are organizations like corporations and companies (like production companies and licencors).
The ContentExplorer can manage all data of persons and companies. Potential duplicates can be merged with data cleansing.
