I couldn’t work out what you mean by DMS. When I googled it, it said “Document Management System” Is that it? I don’t have a very clear concept of what a “Document Management System” is, other than some I’ve seen used by government departments etc that have features like archiving, classification (top secret etc.), a lot of meta data like authors and editors and approvers… It doesn’t seem to really fit this. Tags however are awesome, and I love anything that does tagging. Maybe this is more of a document tagging system?
