mysql - Jena connection to external databases -

-

i have read articles commenting apache jena engine , have found interesting. @ site have found in order store triples, tdb used.

in case, know if, jena application possible load data external databases such mysql or postgresql ones, or "closed" product , can interact tdb , fuseki frameworks.

at moment, don't know if jena engine framework act traditional java war particularities of processing rdf files.

any apreciated.

if mean, connect existing non-rdf data in mysql or postgresql, no. need (dynamically or statically) have conversion layer between database , jena. d2rq can provide that.

if mean, use mysql or postgresql store rdf, yes. see jena sdb. however, tdb faster , scales better.
