[Nepomuk] Re: How to read back the Nepomuk::Resource identifier

[Sebastian Trüg]

Ok, correction: it is not ignored. It is used as nie:url. So if you use
"akonadi:?item=abc" as identifier in the Resource constructor you get a
new resource with a random URI and nie:url property set to the akonadi URI.

Cheers,
Sebastian
