Modelio is an open source modeling environment tool providing support for the latest standards (UML 2, BPMN 2, ...). It can be extended by adding modules which add new functionalities. A large set of modules (free and open source) supporting code management (generation/reverse), modeling standards (TOGAF, SysML, SoaML, ...), document generation, ... is available from the Modelio Store (https://store.modelio.org/). Need help or want to share experience with the Modelio community? Go to our forum: https://www.modelio.org/forum/index.html.

A simple editor for PlantUML. Requires PlantUML (and its dependencies, java and graphviz/dot). Some features: * update the diagram while editing * code assistant to insert ready-made code snipets * written in Qt4, so it should run on all platforms supported by Qt4 and PlantUML * option to cache the PlantUML output to speed redo, undo and loading from disk * can be used as a PlantUML viewer (see the wiki for more info)

This StarUML module implement the UML profile for business modeling (BM). Based on the UP for software engineering (OMG) and RUP (This module supports both specifications). BM is the study of an organization, models real-world organizations. GNU-LGPL 3.0

PlantUml Dependency allows to parse / reverse engineering source files (only Java is supported by now) to generate a PlantUml description, allowing to draw the UML class diagram associated to the source code.

As software architect, you create a set of diagrams describing use-cases, requirements, structural views, behavioral and deployment views. crystal_facet_uml keeps element names and element hierarchies consistent. It exports diagrams in svg, pdf, ps and png formats to be used in text processing systems like docbook, html, latex. This tool runs on your local PC and is based on glib, gdk, gtk, cairo, pango, sqlite.

OWL2XMI is a java project to facilitate the creation of classes UML diagrams. It generates a XMI file from one ontology, this XMI file can be imported using UML tools such as: StarUML, ArgoUML, among others. There are available online version, Visit Proj

This StarUML module for C++ provides practical support for legacy systems. It uses the StarUML as a KDM (Knowledge Discovery MetaModel) framework for existing systems. The module provides an incremental reverse engineering for C++ code with a set of configurable options, such as using namespaces or folder as packages, create attributes for relations or handle properties as relations,...

Eclipse based framework to create interoperability among UML2 and Architectural Description Languages (ADLs). DUALLy works at two abstraction levels: meta-modeling (via AMW weaving models), and modeling (via UML, Ecore models and ATL transformations).

FOML is an expressive logic rule language that supports object modeling, analysis, and inference. It naturally supports model-level activities, such as constraints (extending UML diagrams), dynamic compositional modeling, analysis and reasoning about models, model testing, design pattern modeling, specification of Domain Specific Modeling Languages, and meta-modeling. FOML can reason about: 1. The model meta-data (meta-model level reasoning, or syntax reasoning) 2. Data level: reason about a model and its data (instance model, i.e., diagram) FOML is built as a semantic layer on top of PathLP - a compact logic rule language of guarded path expressions, an adaptation of a subset of F-logic.

Unimozer intends to be a universal modelizer for Java™. It allows the user to draw UML diagrams and generates the relative Java™ code automatically and vice-versa.

There are no constraints, only your ideas and your way of explaining it. GUI is full macro. Shit+? to open help Need java-8 on your system.

BeigeUML is an UML diagram editor. It has two user interfaces - ordinary desktop SWING and Android. Features: 1. Supports UML 2.4.1 compliant class diagram, package diagram, object diagram, sequence diagram and use case diagram. 2. It generates UML class diagram from Java source. 3. It's a doclet that generates standard Javadoc with UML class diagram. This application you can download from Central Maven Repository: https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.beigesoft%22. There beige-uml-swing-[VERSION]-jar-with-dependencies.jar is Swing application and beige-uml-android-[VERSION].apk is Android application. Android version you can find also in Google Play Store. Its source code you can download at https://github.com/demidenko05/beige-uml Source of beige-android-demo (demo of Android tree/file-chooser, list-chooser etc.) still here.

This is a game.Player has to save his target point(staff).There is an enemy tank. The enemy tank will be trying to kill the staff.If staff is killed then game will be over. And if player can kill the enemy tank then player will win the game.

The diagrams are represented in the DOT language and can be interpreted by the visualization software Graphviz (http://www.graphviz.org/). Features: - Use HTML tables as templates for customizing the diagram design - Already comes with predefined connections for some common database systems, new systems can easily be added.

A reverse engineering, metamodel driven tool that scans PHP files and directories, and delivers an UML/XMI representation of the classes / packages found. The XMI code that it generates can be imported into any UML modeling tool. It is available on PEAR.

vipera is a designer of applications for the programming language Python. It has two main objectives: 1) The design of an application from an educative point of view, paying special attention to the documentation and design of classes. 2) The automatic generation of base code for software projects. vipera is a combination of basic tools for the design of applications in the early stages of development, allowing the creation of modules (libraries) and definition of their basic characteristics, such as classes, functions, records, constants and import modules. The design of classes is done graphically, by means of a code similar to UML. It includes an inverse engineering option, that is, from Python scripts, classes and relationships are identified and represented graphically.

a framework library with a template method interface and inheritable classes for an executable process design which produces an executable which is both a GUI and a console application. It provides multi-threading for work items of the provider process .
