Steve,

thank you for the comments. I appreciate that you took the time for the review.

I corrected it.

> Also xsd:integer might be a better choice than xsd:int, to make comparisons with other data easier. xsd:integer is a supported type in SPARQL, xsd:int is not. If you're publishing data in Turtle, then you can just write bareword integers, e.g. 3499879 and they will be xsd:integers.

I changed this to xsd:integer.

> I find the use of predicates with a capital after the namespace a bit jarring (e.g. q:Method), but it's perfectly legal of course.

It could become even more jarring, as we actually will probably not
use q:Method in the export but rather a numeric ID like q:P17234.
On the other hand, we plan to have q-en:Method owl:equivalentProperty
q:P17234 and q-de:Methode owl:equivalentProperty q:P17234 etc. as
convenience URIs.
But that is a completely different discussion, where the draft is not
finished yet: <http://meta.wikimedia.org/wiki/Wikidata/Notes/Multilingual_data>
-- I would prefer *not* to have this discussion yet. I will ping this
list as soon as the first draft for that is finished.

Thank you for your time!

Cheers,
Denny
