Abstract
This article focuses on authoring and using XML Schemas for the purpose of generating an EMF model.
Overview
An EMF Model (files of type *.genmodel) is the hub for importing/exporting other metamodel formats, linking to other EMF models, and generating implementation code. Out-of-the-box, EMF can import XML Schema Definitions (XSDs) into Ecore Models (files of type *.ecore). Similarly, EMF can export Ecore Models to XSDs. But without some additional information, EMF uses a default set of transformations that rarely yields the desired mapping.
Luckily, both Ecore models and XML Schemas have support for annotations. Annotations can be almost anything, but for this discussion, annotations will serve two main purposes
- Provide additional information when transforming one metamodel to another
- Provide additional information on how to serialize/deserialize an EMF Resource, Object, Attribute, Datatype, etc.
