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.

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.

A method and system to represent in UML the resources and external data manipulated by a program to be coded in a procedural language is disclosed. The usual UML class diagram is enhanced with two new stereotypes “Program” and “Data Object”. The program stereotypes applied to an operation and its parameters describe the data manipulated, through the logical definition provided by the Data Object. This model will be enhanced in order to introduce classes on which the Resource stereotype is applied. These classes will be connected to the appropriate logical data definition (the Data Object) and used as parameter types of the operation instead of the Data Object. A second set of stereotypes will be applied to the Resource classes to indicate the physical type of the resource (a file, table etc. . . . ) and its characteristics. Parameters that point to a DataObject or a primitive type will be considered as external data.
