Re: [Dbpedia-discussion] Metaweb has published Freebase data dumps

Hi John,

quite honestly i think you should be outputting RDF , thus preferring
some shallow (maybe syntactic only) compatibility right  away to
correctness (which as we know on the web is not something one could
ever give for granted).

At least you'd show up on sindice.com :-) .. and others could start
doing integration experiments, (e.g. writing a semantic web pipe to do
some mappings http://pipes.deri.org) property mappings etc.

As for URIs use your internal ones, as long as you put enough IFPs or
quasi IFPs  (e.g. primarytopic of links to wikipedia pages, personal
blog pages, etc) we'll figure a way to smush.

But if you dont output RDF yourself  and and one has to rely on
possibly several different external mappings i think people are going
to be less likely to want to use it. (the thing also opens up serious
trust issues.. if i could say "paris.rdf" comes from metaweb then ok i
could apply metaweb trust.. but if it comes from third parties
wrapper services, its hard to know how to trust them)

just my 2 c :-) hope they help

Giovanni
