vcard example does not work

[seebi]

from Xuan Hoa Nguyen:
Sorry for the dummy question, I've read your tutorial here:
https://github.com/AKSW/RDFauthor
and then the source code:
https://github.com/AKSW/RDFauthor/wiki/Edit-resources-with-RDFauthor-using-RDFa
and the example,
https://raw.github.com/AKSW/RDFauthor/91c2099cdda77623ddda49060cc182ab435913be/tests/gui-tests/vcard.html

Still, I can not get it works. Can you please tell me how to run your example here ?

In my machine, nothing happens. It just looks like a normal HTML page.
Can I replace OntoWiki/sparql and OntoWiki/update with something more evident ?
