Hi Eddy, Can you please confirm if any core files are being produced when these crashes occur (if not you need to ensure "ulimit -c unlimited" for user virtuoso is started as) ? If, so would it be possible for you to build a debug version of the Virtuoso Server with -g set in CFLAGS LDFLAGS i

Hi Nirmala, I am slightly confused, back in July you where getting "Transaction aborted because it's log after image size went above the limit" errors performing SPARUL insert queries and advised to the the RDF_LOAD_RDFXML_MT function for loaded large datasets or increase the "TransactionAfterI

Re: [Virtuoso-users] RDF autoupdate timestamp

Hello Mirko, Storing typestamps on statements is a partial case of reification. Unfortunately Virtuoso does not provide any special support for reification --- that would penalize other tasks. Storing typestamps on subjects does not require reification and could be made via triggers, but these tr

[Virtuoso-users] RDF autoupdate timestamp

Hi, I would like to (auto-)remove statements with a certain age from RDF graphs in Virtuoso. In SQL I would create a "timestamp" column with DEFAULT CURRENT_TIMESTAMP, ON UPDATE CURRENT_TIMESTAMP and add an event scheduler that deletes all rows with a given age. I wonder what is the best way to

Hello, if I use a SELECT DISTINCT ?s {?s ?p ?o. ?o bif:contains "Aspirin". } and activate owl:sameAs reasoning, will it have any effect? We want to query for all subjects associated to a certain label, i.e. bif:contains '"Aspirin"' on the LODD data. The problem is, that they contain 7 datasets
