No: you can attach metadata (comments, iptc, most exif, ...) not just to jpg, but also to png, tiff and other, less common, formats. I'm not sure, but I think we can also add dng to this list...
So, no problem with that. 
But you should know, not every software or service out there supports all those metadata on all those formats. Only with jpeg you can be sure that all the metadata will be read (almost) everywhere.

Afaik, as default, digikam copies the text you enter in the caption field into every "caption" o "comment" metedata field available for the image, so you don't need to worry about it. You should be able to read your description/comment/caption everywhere, and services like flickr and stock agencies will import that data in the right way.
