I set my PHP timeout limit to a very high value and let the RDF export run its
course.
The file was eventually generated, apparently without error.
The RDF export contains what I expected to see - a list of properties for that
one page.
It also contains things I did not expect in that file - every pages that this
page links to is also included in the file, along with their own properties.
Is that how the RDF export is supposed to be ?
