Hi,
Does Virtuoso (or any other triple store) support the definition of an
alias for a set of named graphs such as
defining <http://ex.org> to refer to a set of graphs such as
<http://ex.org/1> ... <http://ex.org/n>
The reason is that I want to consider using an approach for triple
management, where triples sharing the same metadata are stored in a
graph*, and an update simply clears the graph and inserts the new data.
However, applications should not have to deal with physical
representation and instead only see a single logical graph.
So in other words: The goal is to avoid having to filter the graphs
explicitely in the SPARQL query as shown below, but rather specify an
alias in the from clause and have the store do the filtering "behind the
scenes".
Select ?s ?p ?o {
Graph ?g {?s ?p ?o}
Filter(Regex(?g, '^http://ex.org/'))
}
Kind regards,
Claus
