Just a remark about what we're doing in Sindice, for all who want to
be indexed properly by us.
we recursively dereference the properties that are used thus trying to
obtain a closure over the description of the properties that are used.
We also consider OWL imports.
When the recursive fetching
Just RDFa and live happy IMO. A machine doesnt care about the messy
part of the markup. The advantage of a single URL to access it too
much to be a match for anything.
It is a fact that people like us like to look at RDF directly as well.
But it should be a problem to use a firefox plugin to
Martin,
partially you could solve the problem yourself by putting the
owl:import triples in your ontology fragments e.g. the fragment, when
served, says owl import so that you're sure the ontology is used as
a whole..
would this do it? :-) fixing the problem in a single location might
be so much

Hi,
there isnt a single answer unfortunately.
Lets take symetric concise bound descriptions (SCBD) which basically
means from the uri you'll get triples around it recursively until you
find other URIs. (so when you find a blank node you keep on going).
This seems a pretty good way to provide

Hi Andreaz :-)
I don't see the difference between the LOD model and the data (including
links) itself. At least to us at Zemanta it is immensely helpful to have
a lot of those links done. It brings down the cost of doing really
innovative stuff to us and I believe to many others too.

The rest of the descriptions seem to be allowed for by current
