[Nepomuk] Re: Need help in solving an error occurred while dealing with Nepmuk

[Vishesh Handa]

Hey Sri

A couple of things -
1.) Use Nepomuk::Tag( tagNameAsAString );
not Nepomuk::Tag tag("resourceTerm"); and tag.setLabel( tagname );

2.) A simple Nepomuk::File( url ), will do fine.
You don't need to do Nepomuk::Resource( url ).toFile() as Nepomuk::File is a
subclass of Resource

I tried out your code and it runs perfectly ( as I said on IRC ), the
problem is from where you call the code. And just to prove that your code
does work, I've created a scratch repo kde:scratch/vhanda/nepomuk-for-sri
You can try it out over there.

I think there are some threading issues, your debug output says :
QObject::startTimer:
QTimer can only be used with threads started with QThread

PS: A mailing list is the correct place to ask question. Not a blog post.
