Hello. Thanks for virtuoso.
Presently we can specify custom dataset for a sparql query with
FROM NAMED declarations. Thus we can specify a custom dataset, whose default-graph is merge of graphs declared with
FROM, and whose named graphs are individual named graphs declared with
This pattern works fine until we have to search among merge of small number of named graphs, by enumerating all of them with
FROM. But if we have to search across merge of millions of small named graphs , whose description matches certain criteria (like, trusted-by-an-authority, extracted-from-specific-resources), then it won’t scale.
Is there any way for us to define such custom-view/ synthetic-graph easily?
