Metadata in SWF files?

Hi again!

I´m playing around with SWF files exported from indesign CS4. I wonder if there is a way to read any metadata from those files. Or is there any? I have not found any AS3 method to trace metadata like time/date or even some unique ID...something that I could use later to specify that file...

Is there some way to check out if InDesign has written some hidden info to those SWF-files?
