Hi Francesco, I tried the Windows Virtuoso 7.2.1 prebuilt binary from June 2015 and was able to successfully create Linked Data Views of the Sample demo database we provide successfully.
Thus what is the database you are seeking to created Linked Data Views off ? Can you provide the schema of the tables at least such that we can attempt to create locally ? Please also provide a copy of your “virtuoso.log” file … Best Regards Hugh Williams Professional Services OpenLink Software, Inc. // http://www.openlinksw.com/ Weblog -- http://www.openlinksw.com/blogs/ LinkedIn -- http://www.linkedin.com/company/openlink-software/ Twitter -- http://twitter.com/OpenLink Google+ -- http://plus.google.com/100570109519069333827/ Facebook -- http://www.facebook.com/OpenLinkSoftware Universal Data Access, Integration, and Management Technology Providers > On 19 Aug 2015, at 21:01, Francesco Balzu <i_ba...@hotmail.it> wrote: > > Hi Hugh, thanks for your help and your time. > > If I run DB.DBA.RDF_AUDIT_METADATA() I get this message (with each of the > allowed parameters): > > Query result: > STAT > VARCHAR MSG > VARCHAR > 00000 Reloading built-in metadata, this might fix some errors > without accurate reporting that they did exist > 00000 Built-in metadata were reloaded > 22023 SR528: Uninitialized property qmvColumnsFormKey in JSO > instance <sys:qmv-87989165e74248977150f5a68b057866> of type > <http://www.openlinksw.com/schemas/virtrdf#QuadMapValue > <http://www.openlinksw.com/schemas/virtrdf#QuadMapValue>> > 42000 The previous error can not be fixed automatically.
