Dear all,
I'm currently testing permissions graph using isql in virtuoso for a GUI
project (https://github.com/askomics/askomics/) at front of a TPS.
I would like know, if it's possible to give rights permissions
(load/upload) dynamically on a subgraph (which is inside a graph with
write permission).
I set up vituoso with following command :
## by defaut without authentifcation, all is hidden
DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('nobody', 0);
## 'user' and 'admin' is two kind of user with select permission by default
DB.DBA.USER_CREATE ('user', 'user');
GRANT SPARQL_UPDATE TO "user";
DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('user', 1);
DB.DBA.USER_CREATE ('admin', 'admin');
GRANT SPARQL_UPDATE TO "admin";
DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('admin', 1);
#I create two main graphs (a public and a private) for manage visibility
and insertion of data
DB.DBA.RDF_GRAPH_GROUP_CREATE
('http://symbiose/igepp.inra.fr/public/user', 1);
DB.DBA.RDF_GRAPH_GROUP_CREATE
('http://symbiose/igepp.inra.fr/private/user', 1);
#the public graph is reachable from anyone and can be manage by the admin
DB.DBA.RDF_GRAPH_USER_PERMS_SET
('http://symbiose/igepp.inra.fr/public/user','nobody', 1);
DB.DBA.RDF_GRAPH_USER_PERMS_SET
('http://symbiose/igepp.inra.fr/public/user','admin', 7);
#the private graph is only available by the user (with write rights)
DB.DBA.RDF_GRAPH_USER_PERMS_SET
('http://symbiose/igepp.inra.fr/private/user','nobody', 0);
DB.DBA.RDF_GRAPH_USER_PERMS_SET
('http://symbiose/igepp.inra.fr/private/user','user', 7);
I would like to insert with the askomics GUI new graphs inside the
private or public graph according the authentification (admin or user)
but actually it does not work.
"Error SR619: SPARUL LOAD access denied: database user 111 (admin) has
no write permission on graph urn:sparql:connait_1480502257.403878"
appear when admin want to insert the graph
"urn:sparql:connait_1480502257.403878" in
"'http://symbiose/igepp.inra.fr/public/user";.
here the request:
