UMLGraph allows the declarative specification and drawing of
UML class and sequence diagrams.
The current features
are part of an ongoing effort aiming to provide support for
all types UML diagrams.
An IEEE Software article titled
On the declarative specification of models
explains the rationale behind this approach.
The tehnology behind UMLGraph was used to draw many of the diagrams
appearing in the books
Code Quality: The Open Source Perspective (Addison Wesley, 2006) and
Code Reading: The Open Source Perspective (Addison Wesley, 2003).
In addition,
the UMLGraphDoc doclet included in this distribution automatically
adds UML diagrams to javadoc documentation.
Many programs build on UMLGraph; follow this link
for more details.
In addition,
Martin Fowler, the author of
UML Distilled, writes:
I thought I'd send you a note saying how much I enjoyed discovering UML Graph. I've long fancied a text based way of describing UML diagrams, but never felt sufficiently time-rich to develop anything.Martin has created a bliki entry describing his ideas of what an ideal textual language might look like.
