Hi Frans,
Currently it is not possible to do this, development ask:
Would a "default" rule set for all cases when graph is not configured
individually or graph is not know at the time of compilation, plus rule sets
associated with graphs. The disadvantage is that the compiler can be smart
enough to propagate constant restrictions so the use of syntax graph ?x { ... }
may not enable default rule set as soon as there's an explicit or implicit
FILTER (?x = <A>) and graph <A> has associated rules_A. Update activities on
storage will obfuscate things in other way. If g_A has rules_A and g_B has
rules_B, what should sparql ADD g_A TO g_B do --- to add original triples or to
add both original and inferred triples? Same is for replication.
Best Regards
Hugh Williams
