Free vs Safe in semweb

Ian Davis is having an RDF breakdown. Seems Dublin Core can't seem to get dc:creator quite right:

That's when my crisis struck. I was sitting at the world's foremost metadata conference in a room full of people who cared deeply about the quality of metadata and we were discussing scraping data from descriptions! Scraping metadata from Dublin Core! I had to go check the dictionary entry for oxymoron just in case that sentence was there! If professional cataloguers are having these kinds of problems with RDF then we are fucked....A simpler RDF could take a lot of this pain away and hit a sweet spot of simplicity versus expressivity

In the free vs safe debate, looks like he's making a run at freedom.
