as an external long term observer of RDF and OWL developments, from where I stand
it looks to me that people have been kicking around screaming about certain hydiosyncrasies
of sw standards representations since they have been released.

 I am glad that they have finally surfaced and that have been picked
up in recent keynote addresses, but there has been a lot of pressure to get people to admit there was something wrong in the first place

It is great to hear sincerity in the keynote - but it is not Pat
that has 'issued a call' - he merely echoing what the rest of the world has been up in arms about and aventually gave in and admitted it
(very kind of ISWC to give him a keynote slot to make what is a grand apology in disguise)

While it is true that heterogeneity (I am being polite - call it messy state of affairs) is a consequence
of 'organic growth' and multiple strands being furthered more or less simultaneously - see what sticks approach -
it is also true that some people who may have contributed to developments differently and avoided or at least reduced
the number of 'errors' being made have been
shut up and marginalised and eventually even kicked out from work groups .

I am fairly convinced that if we do not want the same mistakes repeated in the future, we cannot  rely solely on the same  people and processes  that delivered the situation in the first place, otherwise we are gong to get more of the same thing,
maybe worse, as things get more complex, very narrow thinking is gong to serve us less and less

The SW needs people who have higher level 'systems thinking' skills not to be bullied out of the sw development community
by know-it-all arrongant narrow minded individuals

I welcome Corey's  and OMG and much needed fresh thinking, and possibly different approaches

I think this effort may be premature. At ISWC this year, Pat Hayes issued a
call to substantially revise RDF in a way that is upwardly compatible and
which resolves several outstanding problems with the representation. The
most severe of these problems has resulted in the creation of several new
languages on top of RDF (OWL is an example) whose semantics are not
compatible with the base semantics of RDF. In other words, RDF is being used
as an interchange format.
While I think Cory's proposal is very much in the right direction, I would
like to see the outcome of the debate on Pat's proposals before committing
to creating yet another semantic representation on top of RDF.
Thanks, Jim

Great news!!

Any chance of a URL to an HTML or XHTML doc? Word, PDF, and Open Office
as only options just doesn't play well, especially if the theme is about
Web of Linked Data etc. :-)
