Unified Modeling Language Tools Collaboration for Use Case, Class and Activity Diagram Implemented with HTML 5 and Javascript Framework

As a result of the development of web 3.0, web technologies now make it possible for each user to collaborate in performing a task. This technology allows the users to draw Unified Modeling Language (UML) diagrams online and collaborate on a software project. Unified Modeling Language (UML) is one of the architectural modeling software that is widely used by software developers. This paper aims to develop a modeling tool UML diagrams are class diagrams, use case diagrams and activity diagrams based on pre-existing web using HTML 5 technology combine with JSON service that allows the software developer to work on the same project UML and collaborate each other with good performance more faster than ordinary web.
