Putting the user in control of their data. Another option would simply be to allow users to link to their own file using the "sameAs" property. Cant, be that hard, can it, adding one field? ;) If you can tell me how I can get my public key into a FSW via salmon I'd be very grateful (if that is possible). > > >>> >>>> That was just an example, but the real story here is the law of >>>> "unintended consequences".
