Apple

I want to get a list of all the metadata that spotlight is searching (the list you get in the finder when you do a search in the finder, click the plus button, then select "Other..." from the pop up box).

I am not sure the best way to approach this. I haven't found any "official" way to do this in the documentation. The problem is, spotlight plugins can add their own metadata to the list using the schema.strings file. One way that I think might work would be to search for all the spotlight plugins on the computer, then extract all the keys. That seems like a really crude, non-cocoa way to do this. The other problem is that it appears all the default metadata is hardcoded into spotlight and cannot be extracted, so if apple ever changed them, I would have to update my program.
