 doesn't at least some of this come from the dual use of a uri in the html 'a' tag. <a href="..."> and <a name="..."> one is reference (function if you like) while the other is a ... name. takes a while to get your head around this when playing with rdf. in xul the uri tells something (usually a tree) where to go to get a resource and which parts of it are relevant. in the resource the uri's are used to tag resources for retrieval. in C we use pointers in a similar way: x is the pointer and it's name, &something is where the value is, and *x is it's value. pointers are the strength of C (and it's comprehension weakness) - uri's seem to have a similar role. rick Bullard, Claude L (Len) wrote: >It is the natural sense of it to me as well, although, >given the names of arguments, I can conceive of a URI >as a document itself (particularly if it names a name). > >If I think of the hyperlink as a function a) I win >an old discussion with Goldfarb from a long time ago >b) the framework of objects makes more sense to me >as I can conceive of it as a control. > >Then the range is computed, not declared per se, >and that fits the quantum logic model (the act >of addressing a continuous resource is just >a vector address). > >Now, does that fit what Fielding says.
