Create Virtual Graph Virtuoso -


on knowledge base deployed on virtuoso v7.2.1, i've 2 rdf graphs, namely http://example.com/a , http://example.com/b, populated triples.

i'd create virtual graph http://example.com/vg should represent union of http://example.com/a , http://example.com/b. therefore, change on either http://example.com/a , http://example.com/b should propagated http://example.com/vg.

digging documentation did not find pointers , closest thing do, so-called rdf view, operates on tables , not rdf graphs. has suggestion on how implement it? in advance

currently, virtuoso way graph group.

you'll need use db.dba.rdf_graph_group_create(), db.dba.rdf_graph_group_ins(), , related functions.

the graph group view of of union of member graphs, changes member graphs reflected through graph group. there no change propagation, such.

for future -- virtuoso-specific questions faster response on virtuoso users mailing list, openlink support forums, etc.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
