Thank you for your support.Two more things to take into consideration on the previous statistics. Even though the total number of triples in<rdfs_g> and<g> might be 8 and that there is 1 class instance in both graphs this does not mean that the triples are the same in<rdfs_g> and<g>, e.g., the triple (<uri> rdf:type ?o) is different in<g> and in <rdfs_g> w.r.t ?o (i.e., 2 different class instances, where in <rdfs_g> is only one inferred). Moreover, I have installed 06.01.327 version on ubuntu. Meanwhile I do not promise that I will upgrade virtuoso (maybe only after an official response) because of the possible danger of messing up with the dataset and/or current configuration.
Please upgrade as this helps resolution of this matter. You can dump your dataset and then reload into the upgraded instance. You can also make backup and restore. Kingsley

Naturally, you have to bear with the support turnaround which is always based on what's on the queue etc.. They (or I) will get back to you.

I think and I am afraid I cannot "share" the dataset I am testing ( if you meant that). I changed my query to selection: sparql define input:inference<something> select * from<g> where{?s ?p ?o} limit 20 I do not know how the inference is evaluated on the triples and how the result is returned, but in the first 20 results I do not see any new inferred triple.Without sharing a SPARQL URL you can share the results of a SELECT query e.g., a count of the records when using a SELECT query.

So I use the following query to accomplish that: sparql define input:inference<something> insert into<rdfs_g> {?s ?p ?o} where{graph<g> {?s ?p ?o}} (1) I then check for a specific uri in rdfs_g and I see the same inferred triples but NOT all of them and the number of triples is the same. To further test it I apply the same rule for this specific uri: sparql define input:inference<something> insert into<rdfs_g> {<uri> ?p ?o} where{graph<g> {<uri> ?p ?o}} (2) Comparing the<rdfs_g> to<g> there is big difference on the number of triples (i.e. 15 to 8 rows respectively) and I think I see the total inferred triples. What is wrong with that?? I have test it (1) on a smaller dataset that <g> and works fine. I am begging to lose my mind on this. How could I debug this?There is a threshold in the ini file which defines how many triples are returned at max. Perhaps this is the source of your problem?! Ciao CarinaYes re. INI. Alternatively, one diagnostic option re. assistance from us would be to change the INSERT into a SELECT and then share the SPARQL protocol URL.
