Check out the same/similar set of files using SVN:

svn co https://rdfhomepage.opendfki.de/repos/rdfhomepage/trunk/rdfhomepage/myrdfhomepage

Before you start something else, you should call install.sh if you are installing rdfhomepage on a UNIX machine.

Then, you should edit the files (especially config.php and homepage.rdf), and then test and play around a bit.

Well, and you MUST have a FOAF file for rdfhomepage to work!

You may want to check out the rdfhomepage package (in particular, if you are not a DFKI worker):

cd ~homer/public_html/whereever/
svn co https://rdfhomepage.opendfki.de/repos/rdfhomepage/trunk/rdfhomepage

The rdfhomepage package also contains a directory myrdfhomepage providing you with some initial files you can use to view, edit, and replace.
