In natural languageFootNote(well, English anyway. In Spanish, they say "me llamo ...", in Italian "mi chiamo ..." i.e. "I call myself...".), we say "My name is Dan" and "I am Dan" almost interchangeably. By analogy, folks tend to write
<rdf:Description rdf:about="http://www.w3.org/People/Connolly/"> <dc:creator>Dan Connolly</dc:creator> </rdf:Description>
<rdf:Description rdf:about="http://www.w3.org/People/Connolly/"> <dc:creator rdfs:parseType="Resource"> <foaf:name>Dan Connolly</foaf:name> </dc:creator> </rdf:Description>
almost interchangeably. But if you think formally, i.e. like a machine, these are very different. The first one seems to say that a web page was created by a string starting with the letter D. The second is much more clear: a web page was created by a person whose name is a string starting with the letter D.
