I cannot check it right now due to a lack of reliable Internet  
connection, but there should be a link to

http://www.ebusiness-unibw.org/wiki/GoodRelations_Recipe_8

somewhere on the results page of the tool that explains the link /  
meta approach.

Note, however: We tried three generations of form-based annotation  
tools for GoodRelations data, and most non-academic users are either  
lacking skills or privileges (or both) to properly publish  
GoodRelations data in RDF/XML as files, so we really now recommend  
RDFa in "empty" div elements as the default mechanism for publishing  
RDF data.

Most site owners failed to publish the goodrelations.rdf file properly  
or did not publish it at all, while the "RDFa snippet style" approach  
has drastically increased the ratio of actually deployed content.
