I would also commend Mark Butler's "Is the Semantic Web hype?" I am
glad that he has updated his slides since I read it a while back while
wrestling with the whole RDF vs XML question. I wrote up my thoughts
on my wiki: http://raymondyee.net/wiki/FiguringOutRdf I was
specifically wrestling with the question of whether RDF would help
solve the problem of interoperating among metadata specifications. For
instance, if I need to convert among between DC, MODS, and Amazon
metadata; among METS, IMS Content Packaging and MPEG 21-2; between
Microsoft Office 2003 XML and OpenOffice.org XML, where can I use RDF?
At that time I came up with the following conclusions:
Not having taken a closer look since that time, I don't know whether
I'd stand by those conclusions today. I suspect that I would.
is promising technology in spite of all the confusing hype around it.
is not a monolithic topic. RDF can be used independently of the
Semantic Web. RDF is not inherently tied to XML.
RDF triple concept is a simple, elegant, and seemingly powerful one at
is obscure to the uninitiated and makes it easy to confuse the
relationship between RDF and XML.
Tools help a lot to make RDF understandable -- and usable.
1.0 is a good place to start with RDF.
filled assessments of RDF and the somewhat related Semantic Web are
hard to find.
RDF vocabularies is probably easier than blending XML vocabularies but
it's not magic either! Some human must do the mapping of meanings
much abstraction and confusion might kill off RDF.
Bruce, have you tried the Piggy Bank 2 Firefox plugin-in? I think that
I will take a look at this time and suspect that it's a nice place to
get into both RDF and Firefox.

Their conclusion is that RDF and XML are complementary technologies
(though they're seeing XML as a source for RDF, via XSLT).
Anyone that wants to play with an application of this (from SIMILE)
should install the Piggy Bank 2 Firefox plug-in. They use a
