Model Driven Specification of Ontology Translations Automatic Generation of Ontology APIs Using Templates in OWL Ontologies Conclusion of Part IV Conclusion The next enterprise computing era will rely on the synergy between both technologies: semantic web and model driven software development (MDSD). The semantic web organizes system knowledge in conceptual domains according to its meaning. It addresses various enterprise computing needs by identifying abstracting and rationalizing commonalities and checking for inconsistencies across system specifications. On the other side model driven software development is closing the gap among business requirements designs and executables by using domain specific languages with custom built syntax and se
