The CIA World Factbook [1] includes various facts like
population: 26,813,057 (2001 est.)
The CIA World Factbook in DAML [2] encodes this as
<rdf:Description rdf:about="http://www.daml.org/2001/09/countries/fips#AF">
<population rdf:ID="stmt1">26813057</population>
</rdf:Description>
<rdf:Description rdf:about="#stmt1">
<year>2001</year>
<rdf:type rdf:resource="http://www.daml.org/2001/12/factbook/factbook-ont#Estimate"/>
</rdf:Description>
using RDF statement IDs.
Such "tagging" of statements is very important for many of
our applications, and one of the major advantages afforded
by the Semantic Web [3]. Unfortunately, reification is the
only current RDF mechanism to support this. I hope most
parsers will (continue to) (allow users to) "short-circuit"
the implementation by attaching the statements in the
resulting model while avoiding or ignoring the extra
triples.
