The document describes ODASEODASE, an ontology-driven architecture and software engineering platform that aims to improve software quality, productivity and flexibility. Key points: 1) It separates application complexity from code through executable business ontologies that define 100% of the business logic. 2) This allows bugs to be eliminated early as the ontologies act as testable specifications for code generators to automatically produce business APIs and software. 3) Customers report being incredibly agile with a pure business focus and radically simplified IT systems through less hand-written code.

Why – Issues with Software
The hardest part of the software task is arriving
at a complete and consistent specification, and
much of the essence of building a program
is in fact the debugging of the specification

How – Ontology-Centric Software
• Hundreds of definitions, not millions of LOC
• Executable specifications: testable, explainable
• 100% of Business Logic, zero defects
• W3C standards
Business ontology
Business and IT cleanly separated
Business and IT share a common language
Bugs don't enter, don't propagate :
• Business API generated automatically
• IT uses a definition of the Business
• IT writes 20 x less code to complete the software
• IT focuses on the quality of the implementation
IT programs

Benefits
Ontology
Lowest cost for change
Deeper understanding
Defects identifies very early
Programs
Hard to change
Defects identifies too late

What – MCit ODASEODASE®®
ODASEODASE (Ontology Driven Architecture and Services Engineering) = MCit tools and platform
Business Ontology defining 100% of the Business Logic
• OWL for concepts, properties, axioms, instances
• RDF for data represented universally as triples (subject, predicate, object)
• Business Rules in extended SWRL (Semantic Web Rule Language)
• Declarative Workflows expressed in OWL and SWRL
ODASE WorkbenchODASE Workbench = Model checker (test, explanations, verification)
ODASE HedwigODASE Hedwig = Code generators for Java, C# (and future languages)
ODASE PlatformODASE Platform = All-in-One (reasoners, stores, workflow engines...)

Summary
 Separate the application complexity from the program itself
 Eliminate the errors at the source
– Today, much of the effort goes into testing and the repair of bugs
– Productivity, quality and flexibility radically enhanced
 Iterative extraction and refinement of the application requirements
– The client usually does not know upfront what he wants
– The client almost never thought of the problem in the details necessary for specification
 API automatically generated so that the ontology drives the application
– The Business Logic is something “real” – the ontology – expressed using standards
– Hand-written code is added to complete the implementation
