Goals:

• Provide a major mode for editing UML class diagrams.
• Support import and export of existing code. (this is done via a plugin layer so that anyone can develop these modules). Semantic will provide the necessary framwork to import existing code.
• Support export to graphical formats. Emacs is not an ideal method to share UML diagrams with others. That said we should support export to a format other than text or source. Ideally we would export to something like SVG which we could in turn be used to create a PNG diagram of your code. An example of what a true UML graphical view should look like is available here.
• Support UXF for diagram/source export. This is eventually needed so that our UML diagrams can be imported into other UML editors. Ideally we would use this as the basis for generating SVG with UXF as the source and then apply an XSLT stylesheet to generate SVG.
• Round trip engineering will be kind of tricky but should be possible. The trick will be using semantic to merge UML back with the source. We have to be careful not to destroy existing code. Note that even though we support round trip engineering it may be impossible to support this for all major mode/languages and this may be done on a language by language basis.
