Hello,
RDF-Reification is being used for describing triples and historical data, i.e. A had a name John before 2019-12-31, and A has a name Bob from 2020-01-01.
And SPARQL could query: what is Aâs name now? and what was Aâs name before 2020-01-01?
Is there any virtuoso native method?
Thank you very much.
