PyReverse is a set of tools for reverse engineering Python code. So far, it features dependency analysis tools, documentation generation, and XMI generation for importation in a UML modeling tool. A special module can be used to generate files readable by Argo UML.
currently PyReverse build a representation of the source tree with:
- docstring for modules, classes, functions
- exceptions raised in functions
- modules attributes, functions, classes
- classs attributes defined in the class scope, inheritance links
- class instances attributes defined in the __init__ method. If possible, get the default value
- functions parameters name and optional default value
- detection of interface/abstract classes and visibility using regular expressions
- detection of links between classes using attributes default value
PyReverse provides modules which use this representation for:
- producing a XMI 1.0 UML 1.3 DOM representation
- creating PGML diagrams definitions according to the project representation, the XMI definition and a XML file which describes briefly the content of the diagrams (see ???). Those diagrams can be readen/edited with Argo UML
- generating UML diagrams readable by VCG (see ???).
- analyzing dependencies (see ???).
- generate skeleton for unit tests, using the unit testing framework for the standard library.

Umbrello UML Modeller is a Unified Modelling Language diagram programme for KDE.
Umbrello UML Modeller allows you to create diagrams of software and other systems in a standard format.
Our handbook gives a good introduction to Umbrello and UML modelling.

- Bugs/wishes from http://bugs.kde.org:
- Preprocessor keywords ignored which causes endless loop in code import (119125)
- Code generator for D language (124805)
- Unstable saves and loads, class names become dirty (145709)
- Crash on deleting class in list view (145762)
- Class attribute documentation not generated for python (145916)
- Python code generator does not wrap lines properly (145918)
- Attribute documentation not generated for Export to XHTML (145972)
- Crash when moving a class in a Java UML diagram (146058)
- Arrowheads are not shown (146064)
- Crash when creating a class that refers to more than one other classes/datatypes (146367)

dia2sql is yet another dia2sql converter. It uses libxml2 to parse UML objects from a Dia diagram and generates corresponding SQL code to create the tables specified in the UML diagram
It takes one or more filenames and outputs to stdout. Multiple files are considered as one database by merging multiple tables with the same name.
Enhancements:
- This release has been rewritten in C and adds support for database views.

ArgoUML is a pure Java open source UML CASE tool that provides cognitive support for object-oriented design.

JGraphpad is a diagram editor for Swing that offers the functionality to create flow charts, maps, and UML diagrams.
This release compiles with JGraph 5.7.3.1. Toolbox buttons to create edges or vertices no longer persist selection state. The former behaviour can be restored by setting GPMarqueeHandler.remanent to true.
The GPMarqueeHandler, GPGraph, DefaultGraphModelFileFormatXML, and GPUserObject classes were moved to org.jgraph and their constructors are now protected so that JGraphpad is easier to extend from as a library without changing its code. Various warnings were removed and a general code cleanup undertaken.
Main features:
- Export to XML and JPG
- Built-in Object Library
- Overview
- Interactive Layout
- Print Support
- Page View
- Automatic Zoom
- Grid
- Drag and Drop
- Search
- Minimum Spanning Tree
- Shortest Path
- Component Count
- Background Image
