A method, program and system for mapping ASN.1 data to an object model are provided. The invention consists of identifying the start of a data stream and then generating a new object name for the data. Next, the data is parsed to get the identifier and the data length. Then the data's tag type is analyzed. If the tag type is simple, a class diagram is generated for the data and then the source code for the data is generated. If the tag type is not simple, a subroutine is called to further parse the data before generating the class diagram and source code.

A utility transforms a class diagram representing an ontology, such as a UML class diagram, into a fully-described, standard representation of an ontology such as OWL file. It may be based on Rational Software Architect (RSA) and its model transformation capabilities. The RSA transformation framework uses a Visitor-like pattern for iterating over all of the UML elements in a UML diagram. The framework allows the developer to configure ‘Rule’ classes that are executed when different types of UML elements are encountered. Each UML element is visited once, which causes each rule to be fired for each element type. Rules are configured for just those UML types that are of interest to the transformation, for example classes, primitives, properties, packages and instances. Each rule in the implementation is then written to delegate to a Registrar class, which has a method for building the ontology model from the registered UML elements.

A class diagram can be created for an application. The application can use a modeling language. The application can be configured for creation of the class diagram. The class diagram can comprise classes and relationships. The application can also be configured for creating flow diagrams comprising actions, relationships, and definitions of model element types. The application can also be configured to create new model elements in the class diagram and flow diagrams. A program new model element type can be applied to relevant class operations in the class diagram and a resource new model element type to relevant data classes of the class diagram. A flow diagram can be created per program of the application. The flow diagrams can be applied as many new model element types as different types of actions exist in the flow diagrams.

User is given the new modeling capability, a Semantic Lasso, which allows grouping of the model elements, so they can be mapped or transformed to the high-level concepts of business ontology. Such grouping is done by drawing of the line contour around relevant to advertised high-level concept model elements on one of the OMG Unified Modeling Language (UML) class diagrams. In addition the user is given a capability to specify extension points of the high-level concepts and the projection of such extension points to the individual model. Another tooling capability, a Semantic Transformation Lens, allows dynamic graphical projection of the individual model fragments to the high-level concepts as those elements are being selected. Semantic Transformation Lens provides the mechanism of reasoning-based smart selection.
