The easiest way to start with rdfhomepage is to download the "my_rdfhomepage_sven.zip" (see Attachment below), a ZIP-file containing a snapshot of Sven's rdfhomepage configuration & data. You can look into, edit the files (especially config.php and homepage.rdf), and then test and play around a bit.

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
