The Whole Platform is a technology for engineering the production of software. We provide an Eclipse based Language Workbench for developing, manipulating and transforming languages using a model driven approach.

ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.

PROCOL space-based framework for multi-core. Based on LighTS (http://lights.sourceforge.net/). More to come soon ...

Linguistic Tree Constructor (LTC) is a tool for drawing lingusitic syntax trees of already-existing text. It is a syntax editor, not a text editor, so the text has to exist already. It is best suited for large-scale, rapid creation of hand-annotated treebanks. The user can define their own node categories, and can label each node with labels, also definable by the user. LTC supports "generic", X-Bar and RRG trees. Supports interlinear texts in SIL SFM format.

A fast and reliable tool, written in Java 8, for generating professional UML sequence diagrams from text. Supports actors, con-/destructors, threads, broadcasts, notes, and fragments. Can serve as a Javadoc taglet. Exports PDF, (E)PS, SVG, PNG, ... The source code is hosted at http://github.com/sdedit/sdedit

Mimosa is a modeling and simulation platform, covering the process from building conceptual models to running the simulations. The specification uses ontologies and an extensible set of formalisms for the dynamics. The simulation kernel is based on DEVS.

Calculation of camshafts - allows to define a camshaft profile on the set trajectory which should provide the given mechanism. The trajectory can be set graphically, co-ordinates or function.

Code 2 UML is a tool for constructing UML class diagrams from java .class and .jar files. Requirements: JRE 1.6

The Shrimp suite provides interactive visualizations of graph-based data. Creole (Eclipse plug-in) visualizes Java source code. Jambalaya (Protege plug-in) visualizes ontologies (including OWL), & Stand-Alone Shrimp visualizes RSF/GXL/PRJ/PPRJ files.

Support for more productive Model Based Systems Engineering, following the recommendations in the Cookbook of the INCOSE SE2 Challenge team http://mbse.gfse.de The Plugin for the MagicDraw modelling tool provides support for model based document generation which ties together system model and documents to keep them up to date and consistent, using a AWYSIWYG editor in MagicDraw. It provides basic support to model variants and extract variants from a system model. It provides support to generate organizational structures according to the SE2 Cookbook recommendations. It provides basic pattern based support to reason on a system model, for example to extract numbers like total power, cost, power consumption for a given product tree The MBSE plugin for MagicDraw requires MagicDraw 17.0 SP4 or higher with an installed SysML plugin 17.0 SP5 or higher. Installation instructions can be found in the file ReadMe.txt in the download area as well as the corresponding UMs.

automated refactorings, source-code metrics, audits and corrective actions. install as a stand-alone application or as a plug-in to Eclipse or NetBeans.

NOTE: The GROOVE codebase has moved to https://github.com/nl-utwente-groove

Extracts dependencies and OO metrics from Java class files produced by most Java compilers. Computes API differences between versions. No source needed. Includes both Swing and command-line interfaces, with XSL stylesheets for formatting output.

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.
