i don't know ... i think you guys have lost the signal.  If the ending
triples are not informative, then they are useless.

>>  Hi John and Denny,

>> @Denny: For your request RDFa should be fine, if you just want to include:
>> <http://sws.geonames.org/4951788> <http://sws.geonames.org/4951788> a
>> owl:Thing .

>> Note that the resulting RDF does not contain any provenance information,

>> You are loosing any reference to "Springfield" as RDFa parsers don't

>> Turtle in HTML would also be an easy option:
>> http://www.w3.org/TR/turtle/#xhtml
>>
>> ITS 2.0 example:
>> <p>It is well known, that <span its-ta-ident-ref=
>> "http://sws.geonames.org/4951788" <http://sws.geonames.org/4951788>>Springfield</span> has mild summers and short, but hard winters.</p>
>> NIF:
>> ...
>> <http://example.com/doc.html#xpath(/p[1]/span[1]/text()[1])><http://example.com/doc.html#xpath%28/p[1]/span[1]/text%28%29[1]%29>
>>     itsrdf:xpath2nif <http://example.com/doc.html#char=23,34><http://example.com/doc.html#char=23,34>.
>> <http://example.com/doc.html#char=23,34><http://example.com/doc.html#char=23,34>
>>     rdf:type              nif:RFC5147String ;
>>     itsrdf:taIdentRef  <http://sws.geonames.org/4951788><http://sws.geonames.org/4951788>;
