Hi!
Data living in an RDBMS engine distinct from Virtuoso
is handled via the
engines Virtual Database module i.e., you can build powerful RDF Views
over ODBC- or JDBC- accessible data using Virtuoso. These view also have
the option of being materialized etc..
Yes, but the way the data are stored now is JSON blob within a text
field in MySQL. I do not see how RDF View over ODBC would help it any -
of course Virtuoso would be able to fetch JSON text for a single item,
but then what? We'd need to run queries across millions of items,
fetching and parsing JSON for every one of them every time is
unfeasible. Not to mention this JSON is not an accurate representation
of the RDF data model. So I don't think it is worth spending time in
this direction... I just don't see how any query engine could work with
that storage.
