<pre wrap="">I miss the whole discussion, but RDF objects in statements are either
literal, blank nodes, or URIs.
like this (turtle syntax):

Yes, but xesam decided to limit objects to literals only(as well as other
limitations) and lift them only if it is necessary.
That is xesam is fully RDFS-compliant, yet we implement the smallest necessary
subset of it for performance, coding complexity and other considerations.

adding URL won't hurt much.<br>
<br>

btw, to throw them in here, perhaps somebody needs them<br>
here are the links to the relevant other standards, I am currently
writing a document for something else and gathered them. They use
string, boolean, datatime, float. <br>
