done, but changed a bit to get rid of "different kinds" repeat of words
and give more emphasis. 'However, RDF is crucial when merging different
kinds of information, such as mixing calendar data with review data .
The cost of
combining and extracting different kinds of data goes down if all
the data can be transformed via GRDDL into RDF to advantage of RDF's
ability to easily "mash-up" data'

changed to  'Using the XFN links in Jane's page which identifies the
URIs of people Jane trusts, by matching URIs we can select only those
reviewers who are Jane's friends, as done in <a
href="hotelquery3.rq">this further improved query</a>.'

Well, let's change it to http://example.org/attendance

good catch, now changed so they match and use valid example data, since
it doesn't work since 'Dataset not specified in query nor provided on
command line.' .
