Description

Dynamic datasets, where the dataset to query is constructed out of the graphs of the underlying dataset behave differently for in-memory and TDB datasets.

TDB supports them natively when FROM, FROM NAMED are used.

SPARQL_QueryDataset#decideDataset provides the feature for SPARQL protocol (default-graph-uri=, named-graph-uri= externally to the dataset.

Other datasets do not support the feature. Henc, in-memory dataset services does not support it when FROM, FROM NAMED used but does when default-graph-uri=, named-graph-uri= used.

• relates to: JENA-1846 Add CORS to Fuseki main
• supercedes: JENA-1001 named graphs set not empty if no FROM NAMED clause given
• supercedes: JENA-1002 specifying a FROM clause still selects from the unnamed default graph
