Subject: RE: [obix-comment] href in ref element
The difference between uri and ref is that uri is a property which happens to be of type "uri". Ref is merely a hyperlink to an object of some other type. This is also the reason we use href over val for the ref's URI. The major difference is that uri's probably never map to an oBIX object but a ref *must* reference an oBIX document. I think your contract example uses href inheritance which as of now we don't support.

Why we are not using val to store reference like uri? And if we do store reference in val for ref element, what is difference in ref and uri elements? Consider following example. <ref href="/people/Greg-Brady"/> In this case I loose ability to locate this element by href. Can I define contract like. <obj href="myContract"> <ref name="child1" href="child1" val="/something"/> <ref name="child2" href="child2" val="/somethingelse"/> </obj> By this way I can access reference elements by uri . e.g. /child1 or /child2 Regards, Hemraj Chaudhari.
