Modelio is an open source modeling environment. Based on a 20-year track record of high end commercial products, Modelio delivers a broad-focused range of standards-based functionalities for software developers, analysts, designers, business architects and system architects. It completely supports UML2 and BPMN2, and provides extensions (modules) for SysML modeling, TOGAF modeling, Java (code generation, roundtrip & reverse), and many other targets. Companies and individuals can develop both open source and proprietary add-ons giving users the maximum choice on how to expand on Modelio’s open foundations.

The goal of the project is to build a platform-independent UML modeling library for text-to-diagram translation. The domain-specific scripting language used by the core library is designed for simplicity of diagram sketching.

nAML (.NET Application Modeling Language, pronounced as “namel”) is a visual modeling semantics to model .net applications with wide range of specific details. It contains extremely powerful visual notations and semantics to illustrate complex application components, processes and operations easily.

Napkins Requirements Editor will allow you to enter adjusted and unadjusted function points which will help you estimate how long it will take to complete the application. The user will also be able to enter a Software Requirements Specification which follows the IEEE-830-1998 standardized format. While entering functional requirements additional information can be inputted that will estimate how long the application will take to develop. Comparison between DeMarcos Model estimation and your own estimation for each requirement can be analyzed. The Software Requirement Specification can be printed out via pdf format which can then be reviewed. Comments from reviewers can then be inputted with resolution to each problem.
