Hi, that is pretty much what I have been advocating on foaf-protocol
list few months ago, but not re schema agnosticism, but the profile
syntax agnosticism - defining in a separate spec a brand of webid
suitable for marketing on general level, ie. not only to the tech savvy
people who will understand the value of agnosticism, but only to common
users and engineers who want something which just works and is fully
interoperable with every implementation of it.


I think it would be good if there was agreement of this, eventhough I
know you can dismiss my external comment, not being part of this XG, but
please consider it.
