Yes you can choose the DESCRIBE mode xyz that is the most similar to what you want, copy bodies of two implementation procedures (SPARQL_DESC_DICT_xyz and SPARQL_DESC_DICT_xyz_PHYSICAL) from libsrc/Wi/sparql.sql file of your Virtuoso Open Source sources, paste them to your application, edit, rename by replacing xyz with blablabla, grant execution rights to SPARQL_SELECT role, and use new "blablabla" describe mode in queries. The DEFINE for describe mode may be placed to the sparql endpoint configuration as well as any other DEFINE, if needed. Best Regards, Ivan Mikhailov OpenLink Software http://virtuoso.openlinksw.com
