RDF skeleton cannot find basic classes like XSD, FAOF etc....

[JackJackie]

Hi, I installed OpenRefine with the RDF extension. It works fine until I try to add a property and fill in its name. At that point it cannot find the basic classes of XSD and others that have been prefixed. I tried it in various browsers, like Chrome, FireFox, IE..all with the same result. Any idea what's wrong? Do I need to set certain settings in order for the classes to become visible? Thx in advance for your help.

Try the reload option available under manage vocabularies... and make sure you have internet connection because it loads the vocabulary over the Web

Thx for the reply! I already tried that one, deleted the XSD prefix and tried to reload it again. It seems that the reload does not succeed as the reload window is only present for half a second or so. I have the impression that it has to do with my network configuration. Is that possible? Especially because all the browsers that I use have the same issue.

Network issues might indeed be the problem. Are you behind some proxy?

well, at work I am behind a proxy, but my colleague who is sitting opposite to me also installed openrefine and the rdf skeleton and did exactly the same things and he managed to import the basic prefixes. So, we checked our network settings but couldn't find any difference. Then, I turned to you with my question....In the meantime, I also tried this at home where I'm not behind a proxy and I get the same behaviour
