Hi Richard,

I don't agree, but this should be another topic (it may go too long ;-)

Yes. We can use Japanese characters in XML names, i.e. element names
and attribute names without any problems.

I publish a few vocabularies that include Japanese names as properties
(eg.[1], though I don't see much instances suitable for test, since
people tend to use its English-named properties).

Yes, no problem. I prepared a small example on my site that includes
one property "名前" (which means "name" in English). Try the following
SPARQL, and you will get the result
?nick "masaka".

PREFIX ex: <http://example.org/i18n#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
SELECT ?nick
FROM <http://www.kanzaki.com/works/2008/misc/0218-i18n.rdf>
WHERE {
?who ex:名前 "神崎正英"; foaf:nick ?nick.
}

cheers,
