You don't artificially constrain the entire formal system of allowable URIs simply because one application can't cope with that entire system. In the same way that the XML Namespaces document _attempted_ to constrain the types of URIs and/or Resources it allowed as namespace names, RDF needs to constrain what it consideres a Resource in order to satisfy its requirements. Now you could talk me into some language to that effect in Leslie's document such that it says explicitly that some applications MAY further constrain the concepts of URIs and/or Resources and that the reader is strongly urged to consult the specifications for their applications for any such constriants. > It may indeed be necessary to allow it to be > "whatever you want" but there must be some constraints if we are to build > useful tools to deal with resources: "whatever you want, but you say what it > is as follows....so that we can design tools which will do the > following...." That's a problem with the tool and as such you need to put a warning on it saying "Don't use this with these things". I.e hammers aren't supposed to be used with screws and screwdrivers aren't used to hammer nails. You don't force everyone to use screws and screwdrivers and say that hammers and nails are verbotten.... > -----Original Message----- > From: Roy T.
