Nigam,
We have long considered this issue, and came to the conclusion that it could
only be done well within a holistic system design. A more intelligent web
dependent upon increasingly well informed people participating requires a
balanced structure of incentives that are properly aligned. And of course it
must be easy for the user to do, which means a great deal of prep work. This
is one of the right questions- one that all others depend upon to a certain
degree. - MM

Interesting thread. From the user perspective we still need a way to
create these kinds of annotations (either on the statements/triples or
on the model/graph). Rolling one's own reification mechanism or using
named graphs (which don't have support in RDF) is a technical decision
point, but what about the question of "how do we get users to provide
either of them?"

I really would suggest the named graphs would be a better
underpinning. Unlike reification, they do have a full semantics and
a
clear deployment model, and they follow in a long tradition of
naming
document-like semantic entities. And unlike RDF reification, they
are
not widely loathed, and they are fairly widely supported.
Well, they are not supported by RDF/XML, which (unfortunately) is the
main serialization format of RDF. Named graphs ARE supported by most
triplestores, but they are mostly already reserved for other uses,
like
the representation of provenance based on the RDF files that the
triples
were loaded from. I think we are also lacking a standard vocabulary
for
graph - subgraph relations, which would be needed if we want to
represent graphs within graphs.
