A code generating framework generates code for a model Application Program Interface (API). The framework comprises three components: an API code generator, a serialization code generator, and a deserialization code generator. The API code generator generates code for a model API. This model API produces a first model instance version in a first language. Code from the serialization code generator converts the model instance into a second version in a different language accessible to other applications (e.g., graphical modeling editors). Code from the deserialization code generator converts the second version of the model instance back into the original language. In a particular embodiment, the code generation framework generates JavaScript/XSJS APIs for manipulating model instances compatible with the Eclipse Modeling Framework (EMF). Serialization and deserialization code generated by the framework, converts the JavaScript/XSJS model instance into XMI recognized by other applications built on top of EMF, and back again into JavaScript/XSJS.

Code generation framework for application program interface for model

In one embodiment, an approach to automated recurring concept extraction, from a plurality of input data models (schemas) is presented. The approach converts input data models to graphs, with typed elements. The graphs are mined for closed subgraphs that have a defined minimum support. The identified subgraphs can be filtered with a relevance metric. These subgraphs are converted to schemas or an appropriate representation, and stored for reuse in a repository. The repository can be used to automate further transformation or mapping of schemas presented to a system that uses the repository. In one example, the repository is used in a schema covering process to perform schema transformation.
