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 do this using an RDF graph? Currently, I insert extra statements with a timestamp for each RDF subject at application level. (E.g. my:Subject my:hasObject my:Object . my:Subject my:lastUpdated "timeStamp"). This is not very convenient and probably not very efficient. So, does Virtuoso provide a mechanism to attach and autoupdate timestamps to RDF statements (and thus to remove old statements) at DB level? Thanks, Mirko
