Saving settings profiles in raw files in aperture

Hi do someone know how to export photos in aperture with raw settings that i have done to some picture. Couse when I do export originals I can only export raw files but without my settings which I have done in aperture. I can also export jpg and there I have my settings which I have done but in jpg file. in Photoshop I have xmp file which remember my settings in raw files. So what to do in aperture to remember my raw files settings on 2 different computers where I use Mac OS and aperture
