Hi Ricardo. I don't understand what you mean by "I’m performing data aquisitiont trough RDF and then creating SPARQL queries to populate RDBMS views" , how do you create SPARQL queries to populate RDBMS Views or do you mean RDF Views, in which case you would be mapping SQL queries to RDF Views which is more the norm ?
As you indicate External Data Sources ie the Virtual Database Engine is not supported in open source as it is a commercial only feature. In what way does the commercial trail license not suffice for your needs in terms of concurrent connections ?
