This is a proposal of how we could proceed in terms of prototyping technology.
I makes sens to think about it already at this early stage since it may influence the choice of furhter partners.
The proposal is to build on the base of Eclipse.
plug-in experience already available with current consortium members
graphical franework available
Some links to the eclipse state of the art
EMF: Eclipse modeling framework (http://www.eclipse.org/modeling/emf/) EMF is a modeling framework and code generation facility for building tools and other applications based on a structured data model. From a model specification described in XMI, EMF provides tools and runtime support to produce a set of Java classes for the model, a set of adapter classes that enable viewing and command-based editing of the model, and a basic editor
GEF: Graphical Editing Framework (http://www.eclipse.org/gef/) GEF allows developers to take an existing application model and quickly create a rich graphical editor.
GMF: Graphical Modeling Framework (http://www.eclipse.org/gmf/) The Eclipse Graphical Modeling Framework (GMF) provides a generative component and runtime infrastructure for developing graphical editors based on EMF and GEF. The project aims to provide these components, in addition to exemplary tools for select domain models which illustrate its capabilities. See also * STP: The mission of the SOA Tools Platform (STP) project is to build frameworks and exemplary extensible tools that enable the design, configuration, assembly, deployment, monitoring, and management of software designed around a Service Oriented Architecture (SOA). The project is guided by the values of transparency, extensibility, vendor neutrality, community collaboration, agile development, and standards-based innovation. STP leverages the Service Component Architecture specification (SCA) as its model. STP is a natural complement to other Eclipse projects, such as the Web Tools Platform and Data Tools Platform, and reuses, as appropriate, components from these projects. (http://www.eclipse.org/stp/)
