Spotlight indexing: feature request proposal

[david bovill]

I am looking for ways to add metadata to external files using  
Spotlight - video files in particular from within Revolution. I think  
it would be very useful if the stack indexing suggestions was  
extended to standard Apple file formats or to any file format with an  
existing system level spotlight metadata plugin (you'd need to know  
or parse the plist structure).

In the meantime I'm looking to use AppleScript or the command line  
tools - but not got anything working yet - any ideas?
