I was mostly refering to Feeds. Like timeline feeds ... Eg a feed of posts talking about films.

You would select the Film DVM (aka Film Feed) and it fetches the appropriate notes - perhaps it fetches anything using the words film, movies, cinema, uses the popcorn hashtag etc etc.

But a DVM is I believe a broader term, it wouldn't have to be a fetching feed function.
