Include all keyword hierarchy in version export metadata?
I've spent a lot of time rebuilding my Aperture 3 Library with a new workflow that includes extensive use of keywords. To simplify I have taken advantage of the keyword hierarchy that Aperture offers.
For example; an image with the keyword "Times Square" inherits "Manhattan", "New York City", "New York", "United States of America"
However, when I export my version of the image the EXIF metadata only contains "Times Square" and does not include the parent keywords. Almost the entirety of work I have done in building my keyword hierarchy is useless outside of Aperture - for example in posting to Flickr.
Is there any method of ensuring that all the inherited keywords are included in the version metadata?
