SharePoint 2007 global document policy

I want to set a global policy where every time someone uploads or creates a document in the share point he will need to enter some basic meta data about the document (like it’s security level and type)
not just on a site level but the entire portal.
we had a policy like that at the 2003 version but it stopped working once we migrated to Moss2007. how to I set it up again ?
