Re: Cwm module to load RDBMS data

Hallo,
The schema I see, if I follow your examples:
1) define a database connection with OWL
2) define a query to that connection, also with OWL
3) have an engine that accepts both the definition and
the query, makes the connection, executes the query
and returns the result e.g. with Euler:
Euler dbconnection.n3 dbquery.n3
Greetings, Guido.
