hi Hugh,
it seems to work now! i was trying to execute a very simple
SELECT DISTINCT ?p WHERE {?s ?p ?o}
i have since tried other things and it seems to be doing the right thing
now. thanks for all this.
in the end i had to repackage sesame with all the dependant virtuoso jars
into a war file ... and redeployed. i also restarted virtuoso - i dont
think this was necesary. then created another repo in sesame but this time
i used dba user.
also i found in my logs lots of these errors:
SQ033: SELECT access denied for column GI_SUPER of table
DB.DBA.SYS_ROLE_GRANTS, user ID 107
(ie when i was not using dba. my user has all permissions, ie
select/update/sponge. has DAV permissions as well).
last question: how do i determine the directType of a subject in a triple?
sorry i keep mentioning sesame but anyway.. sesame generated a "x
directType y" triple; how can i achieve similar with vituoso? i dont see
it in the workbench and querying it doesnt find anything.
at the moment it seems i am getting back the super class only which is
valid but sometimes i want the direct type.
thanks.
