Re: Data "on" the Web vs Data "in" the Web

Hi, Steve,

I’m not an official member of this WG, but am watching on the sidelines licking my wounds from previous WG standardization activities :-)

I’d like to respond to your #3 below.

I would think that it *is* the purpose of the World Wide Web Consortium to “sell” the approaches that it deems to be most worthwhile.
The W3C has spent significant effort developing a particular flavor of information technologies that are well suited to the Web.
RDF and Linked Data are the W3C’s version of open data standards.
W3C doesn’t sell for money, it sells for concept. If its “customers” aren’t buying, then they’re free to go adopt non-Web standards.
But it certainly isn’t the W3C’s job to provide any and all information technology to any and all — only those centered on the Web and to those whom wish to be on the Web.

There are plenty of other standards bodies. They can sell their perspective, too.
