Well, not to start a TM vs RDF holy war, but I hardly think of this as a reson to prefer TM. You can do this as well in RDF: meta-meta-data is simply a matter of reified statements. Nice thing about RDF is that you are free to extend your meta-meta-data as you wish. You don't have to worry whether the RDF spec hard-codes in the idea of "conditional include" or whatever modifier you seek. IMO RDF's power is in its simplicity. In fact, the places where I have a quarrel with RDF is where it tries to add cruft that I think belongs at a higher layer. aboutPrefix is one example. > For example, you can say: > In the scope of WML aware client use this stylesheet, > in the scope IE5 use another stylesheet > and in the scope of NC and IE4 and IE3 use yet third stylesheet. > I used this approach a couple of months ago and quite successfully!. > Same thing applies to the values of XSLT parameters. > > It is clear and "tripleless" (forgive me, Uche) :-))) You're forgiven. Especially since I'm not convinced you've found a weakness in RDF. There are many of those, but I think they're pretty well-known. -- Uche Ogbuji Principal Consultant uche.ogbuji@f... +1 303 583 9900 x 101 Fourthought, Inc. http://Fourthought.com 4735 East Walnut St, Ste.
