Re: [ontolog-forum] [uk-government-data-developers] OMG Issues RFP for Linking Architectures & Models with RDF Linked Open Data


as an external long term observer of RDF and OWL developments, from where I
it looks to me that people have been kicking around screaming about certain
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
