Eclipse Modeling Framework (EMF)

Please note the following important differences between XSDs and Ecore Models regarding multiple inheritance:

'EMF's EClass supports multiple inheritance, which allows you to mix-in structural features like attributes at multiple places in your generated class hiearchy. However, the java language does not support multiple class inheritance, so the actual implementation behind the shared java interface is generated multiple times.'

'XML Schemas do not support multiple inheritance. A Complex Type can only extend one other Complex Type.

As an approximation, XSDs allow attribute groups do be define. They can be reused multiple times. However, each time an attribute group is reused, it is treated as a copy of those attributes, rather than a shared reference.'

Webel - the home of Dr Darren's UML™ Parsing Analysis recipe - is delighted to offer a unique service, the translation of digital texts into UML models capturing requirements, systems analysis, systems architecture, and designs as graphical Unified Modeling Language™ (UML™) models.

What comes in ?

Technical documents from your domain, preferrably as digital text, however the conversion of older documents such as printed materials and scans into digital text is also offered as part of the service.

Candidate source text documents include:

• Software specifications (such as the UML specifications bound to UML model elements).
• Software documentation (which can be bound to reverse-engineered APIs).
• Architecture Documents and systems analyses.
• Software Requirements documents can be "eaten up" and bound to requirements elements such as Use Cases or SysML Requirements.
• Systems Design Manuals can turned into SysML Block models.
• Vision statements can be translated into UML™ posters.
• Science Articles can be translated into graphical UML models, and in some cases then simulated or animated.

What comes out ?

Professional UML™ Parsing Analysis models and diagrams corresponding to every sentence of the source document, together with overview diagrams generated from the union of those diagrams, including Package and Model overview diagrams, Use Case diagrams, systems and architecture diagrams, and professional reports.

In the case where the domain involves scientific or engineering topics with flows, port-based engineering diagrams employing Systems Modeling Language (SysML) can be provided to supplement traditional software engineering diagrams.

Does it run ?

Where there is appropriate correspondence between the domain and software engineering elements, the analysis layer can be related to a design layer of reverse-engineered Java components from existing APIs, or forward engineered to the Eclipse Modeling Framework (EMF).
