Oh, that surprises me. Does this mean that the name of the subject is not opaque, as with URIs [1]?<div>How do I know the relationship between France#Density:2012_pop_estimate_Bilan_2010 and Germany#Density:2009_pop_estimate_CIA_2010?</div>
<div><br></div><div>Sorry, again my own ignorance about topic maps shows. I am much better with RDF and the rest of the W3C semantic web standards. When I said &quot;property&quot; I meant something similar to rdf:property, which is part of the RDF reification vocabulary [2].</div>
<div><br></div><div>But in this case I properly have to concede that I simply do not understand how topic maps work. I thought you were giving triples (they sure looked like triples) but then the semantics of the statement is suddenly encoded in the subject identifier, and this just confuses me.</div>

<div><span><font><font face="Arial">you forgot to

</div><div><span><font face="Arial">No I did not forget 
anything, given the Density &#39;namespace&#39; in the subobject name.

<div><span><font face="Arial">IOW your triple 
merely restates what is discernible from the subobject name.</font></span></div>
<div><span><font face="Arial">Maybe you should

<div><span><font face="Arial">At most I made a 
misstatement that &quot;Estimated is an adjective treated as a subclass of owl:Class&quot;

instance of owl:Class&quot;</font></span></div></div>
