Sony Vegas Metadata and File tagging?

Howdy! I used to use Sony Vegas on the PC and have made the switch to FCP. Im liking all that I see but there was one feature that was great in vegas that i can’t find in FCP. It was the ability to tag your clips eg “falls” “Dave” “Bride” “Somersault” and use the tags to recall the relevant clips.

This was great when making wedding videos for example and you just wanted to quickly find all the clips that had the Bride in it.

Is there something like this via a plug in program or otherwise that can be done in FCP7 or is this done by the naming of files? If so does anyone have a good simple workflow for naming of the files?

Ta!
