Introduction to UniMod

Introduction to UniMod: "Overview

UniMod states for Unified Modeling. Long term project goal is to create unified methodology for application development process that will close the gap between Design and Development phases.

Currently, UniMod project is focused on designing and implementing applications behavior. Already implemented approach adapts SWITCH-technology for UML notation. SWITCH-technology is also known as Automata-based Programming and has it's own Russian site http://is.ifmo.ru/english/."

ASP.Net в моно

You can use ASP.NET in three ways:

  • The mod_mono module for Apache can be used to run your applications within the popular web server
  • XSP is a light-weight web server written in C#
  • Or roll your own server: ASP.NET provides an infrastructure to host ASP.NET in any way you desire.

State Chart XML (SCXML): State Machine Notation for Control Abstraction 1.0


This document outlines a state machine notation that combines concepts from CCXML and Harel State Tables. It is intended to be a general-purpose state machine language that can be used in multiple contexts, including VoiceXML 3.0, CCXML 2.0, and the MultiModal Interaction framework. CCXML [W3C CCXML 1.0] is an event-based state machine language designed to support call control features in Voice Applications (specifically including VoiceXML but not limited to it). The CCXML 1.0 specification defines both a state machine and event handing syntax and a standardized set of call control elements. Harel State Tables are a state machine notation that are part of UML [UML 1.5]. They offer a clean and well-thought out semantics for sophisticated constructs such as a parallel states. They have been defined as a graphical specification language, however, and hence do not have an XML representation. The goal of this document is to combine Harel semantics with an XML syntax that is a logical extension of CCXML's state and event notation. For an overview of the UML notation and a brief outline of its semantics, see E An Overview of Harel State Table Notation and Semantics, below.

For simplicity's sake, the language definitions below refer to the 'properties' of elements, without specifying whether said properties are attributes or children. The markup samples at the end of the document make specific decisions about what is an attribute and what is a child element, but we may revise these decisions as refine the definitions.

For concreteness sake, we use ECMAScript as the language for data elements, but the complete language definition will permit other languages such as XPath to be used as well.
