OK this seems to be interesting stuff.
I've found this page https://www.semantic-mediawiki.org/wiki/Help:RDF_export which seems to work (for a single page), here https://directory.fsf.org/wiki/Special:ExportRDF
To export everything, you should have a script called "dumpRDF.php" as mentioned here https://www.semantic-mediawiki.org/wiki/Help:RDF_export#Exporting_all_data

Could you look for this script? It might be the right way to export all data in RDF.

It dumps only semantic data, not the page contents itself.  I believe your original request was for page content.

So for example, it will tell you about intrinsic properties like when the page was created or modified, and other "built-in" properties like the categories that the page is in.

compare this URL: 

https://freephile.org/wiki/QualityBox

with this dump output:

php dumpRDF.php --page QualityBox
