veri.mcore, the technology developed by ETH Startup Montages AG, lets you embed your business knowledge into languages and tools: tailored modeling and implementation languages featuring the terminology and abstractions used by your domain experts in their daily business, not the terminology of software scientists. Tools adapting to these languages, providing visualization, simulation, and validation of your concepts and idea, in your language. veri.mcore as described on www.montages.com/mcore.html, is an open-source toolset for fast and explorative Business Modeling and prototyping. It is an alternative to capturing concepts and data in Excel, and to visualize them in Visio. At the same time it scales to more complex scenarios than an Access based solution, and it is deeply integrated with major Open Source frameworks for BPMN2, UML2, and other fine granular methodologies, if needed.
