Hi Sunday,

The http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtOAuthSPARQL 
<http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtOAuthSPARQL>  
was pointing to and old ods framework vad and has been updated to point to the 
latest one for the 7.2.2 release. Note also that a different ods framework vad 
is require for open source and commercial as indicated on the page also. 

You can also build the required ods framework vad if compiling from open source 
archive by passing the --enable-ods-vad configure option …

Best Regards
Hugh Williams
