Hi guys,

FWIW I think there is a key distinction between a "Web of Data" and
"data on the Web". Much as I wanted to love Microformats (to pick one
example), when I tried to use them in anger I became frustrated at the
seeming lack of the 'linkiness' we need to truly connect data records
on the Web (or strictly speaking 'connect things described by data
records on the Web). Linked Data addresses this, which is one of the
reasons I'm such a fan.

That said, I'm not sure of the real need for a shared definition.
Isn't this a case of "each to their own" - something the Web is really
good for? Everyone is welcome to their own interpretation, and if
Sindice takes a very inclusive attitude to different data
formats/models then that's your free choice. Ultimately though, aren't
we all just better off getting on and building a Web of Data, whatever
definition we choose, than spending our precious time debating the
