Hi Georgi,

I guess I would question why you want to replicate external triples in
your RDF document, rather than including them by reference to the
source documents...

This is exactly the issue I came up against when developing Revyu,
where I concluded that while the HTML document about a resource may
usefully show external data so humans get the whole picture, there's
something that feels fundamentally wrong about replicating RDF data
rather than just pointing applications to the places where they can
find it.

IIRC then Tim disagreed with this at some point, arguing that two
documents that describe the same resource and are reached by content
negotiation and a 303 from the same URI should contain the same
information to the greatest possible extent. Even where we discount
aspects like navigation and ads in HTML documents I don't agree with
this; HTML and RDF documents have different audiences and therefore
the requirements on them are different. Replicating data all over the
place seems fundamentally un-Web-like and raises exactly the kinds of
issues you've come up against.

On a different note, why publish your owl:sameAs links as CC, rather
than also putting them into the Public Domain and adding social norms
if you want attribution, for example?

Cheers,

Tom.
