Review on SemanticGuide by Jeff Leu

I like that it's easy to use, has many features available out of box (ease in creating custom plugins), can easily be integrated with other tools via API or command line interface etc., comes free as open source software under Apache License v2 license; also there are multiple paid plans depending upon your needs which provide additional functionality at an affordable price point! nothing so far i dislike about this tool - would recommend looking into using if you're serious regarding developing RDF-based applications/ontology driven solutions where data model integrity matters!!
