Re: objects to facts to links to LOD to ???

Hi Ravinder,

Interesting points. I would say that Layer 4 would be "discovery".
Furthermore, this would be an inference layer that would allow discovery.
After having linked data, applications will be able to discover new data. So
maybe layer 4 and up are part of the applications that enable discovery.
Anyways, that is what I see what the semantic web is about: discovery and
serendipity.
