Informator can be used in many OS X applications
Enablers for Adobe Indesign, Quark Xpress, Ragtime, FileMaker Pro, Apple IPhoto and Extensis Portfolio are contained already in the Informator package. So getting file information is now much more easy in these applications now. Other enablers are in preparation.

And you can create your own Enablers for your favorite app! Suppositions for that are, that you know a little bit about Apple Script and that the target application is scriptable.
