Open Source UML Tools

ActivityScript takes an activity diagram (created with a UML tool) and executes it's contents. The content of Activity boxes are executed, the Guards of a Decision box are evaluated to control program flow and Fork boxes initiate new threads.

ContRap is a free symbolic C/C++ rapid software prototyping toolkit.

The CoreASM project focuses on the design of a lean executable ASM (Abstract State Machines) language, in combination with a supporting tool environment for high-level design, experimental validation and formal verification of abstract system models.

Eclipse plugin for Prototyping Visual Interpreters and Debuggers for Domain-specific Languages.

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.

The Java Aspect Metamodel Interpreter (JAMI) is a research framework for modeling and experimenting with aspect-oriented programming languages. Common language design concepts and their operational semantics are modeled, and can be run by an interpre

ATTENTION! For various reasons, the infrastructure of the Reuseware project has moved. All information and latest versions are available via the new Reuseware webpage: http://reuseware.org

This is an Hierarchical State Machine (aka Statechart) engine written in Java (1.5 +) Actually we will develop only support for a subset of UML 2.0 semantics but, in future, we hope to add support for other semantics.

Water: a fast, secure, dynamic OO language and database. Water is an all-purpose language (and meta-language) that runs Web applications in the browser or server-side. Water is compatible with .NET, Java, and C on Windows, Linux and Mac OS X system.

cy.prus is a cross platform simulation environment for medical cybernetics and systems biology. Its purpose is to provide both a facility for simulating life and a GUI for easily constructing biological information processing structures based on XML.

Frag is a dynamic programming language, specifically designed for being a tailorable language, building Domain-Specific Languages (DSLs), supporting Model-driven Software Development, and for being easily embeddable in Java.

M3Actions is a framework to define operational semantics in MOF metamodels. It provides a graphical action language to define model behaviour, a simulator, debugger and execution trace recorder, build on top of eclipse modeling projects (EMP).

NexJ Scheme is an open source project providing an efficient and powerful Scheme interpreter that executes in a Java Virtual Machine.
