Abstract: A method and apparatus, including a computer program product, implementing techniques for providing a context building tool that facilitates the building of a context from an existing model or context. The tool can receive a model specification and generate a storage area structure including multiple nodes, each node corresponding to a model class, multiple attributes, each attribute corresponding to a model class property, and relationships between the nodes and attributes based on the relationships between the model classes. The tool can also receive a context specification and generate a source storage area structure including one or more source nodes, each source node corresponding to a target node, one or more source attributes, each source attribute corresponding to a target attribute, and relationships between the source nodes and source attributes based on the relationships between the target nodes and target attributes.

Abstract: A pluggable model framework in a model-view-controller (MVC) environment. The pluggable model framework contains elements that relate to one or more of a development tool for an application, a metamodel that defines development objects associated with the application, a generator for generating code based on the metamodel, and an application run-time. The pluggable model framework includes an extension point that corresponds to at least one of the elements. A plug-in interfaces to the pluggable model framework by way of the extension point. The plug-in corresponds to a model used by the application.
