Hi!
I think in terms of the dump, /replacing/ the Turtle dump with the N-Triples dump would be a good option. (Not sure if that's what you were suggesting?)
No, I'm suggesting having both. Turtle is easier to comprehend and also more compact for download, etc. (though I didn't check how much is the difference - compressed it may not be that big).
to have both: existing tools expecting Turtle shouldn't have a problem with N-Triples.
That depends on whether these tools actually understand RDF - some might be more simplistic (with text-based formats, you can achieve a lot even with dumber tools). But that definitely might be an option too. I'm not sure if it's the best one but a possibility, so we may discuss it too.
(Also just to put the idea out there of perhaps (also) having N-Quads where the fourth element indicates the document from which the RDF graph can be dereferenced. This can be useful for a tool that, e.g., just
What you mean by "document" - like entity? That may be a problem since some data - like references and values, or property definitions - can be used by more than one entity. So it's not that trivial to extract all data regarding one entity from the dump. You can do it via export, e.g.: http://www.wikidata.org/entity/Q42?flavor=full - but that doesn't extract it, it just generates it.
