Though UML includes action semantics, its higher level constructs and object semantics are inconsistent. Motivated by Lamport's approach, this paper proposes

UML is a software modeling language with a graphical notation and underlying semantics. It is often assumed that diagrams must be informal. While we can use UML in an informal way, it has semantics and precise models that we can create by using it in a consistent manner.

There are two fundamental premises regarding the nature of UML semantics in UML 2.0 that need to be stated up front. The first is the assumption that all behavior in a modeled system is ultimately caused by actions executed by so-called “active” objects (explained below). The second is that UML behavioral semantics only deal with . event-driven • UML Semantics. A metamodel that specifies the abstract syntax and semantics of UML object modeling concepts. • UML Notation. A graphic notation for the visual representation of the UML semantics.

With an up-to-date view of the results of UML semantics and the practical applications of semantics development, this book presents the only coherent and integrated account of the leading UML 2 semantics work and its applications. With contributions from renowned experts in the area of UML 2 semantics and its applications, the book covers semantics of UML 2 diagrams, OCL, state machine

OMG RFP “Action Semantics for UML” focuses exclusively on the action semantics. We contribute in this work by giving an action semantics with the automaton model. Overview: This paper is divided into two main parts.

We define a subset krtUML of UML which is rich enough to express such modelling entities of UML, used in real-time applications, as active objects, dynamic

UML, short for Unified Modeling Language, is a standardized modeling language consisting of an integrated set of diagrams, developed to help system and software developers for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems.

semantics also deals with real time and with multiple state instances. We ﬁrst give an informal description of our semantics and then formalise this in terms of labelled transition systems. We compare our semantics with other semantics for UML activ-ity diagrams and workﬂow modelling by analysing the diﬀerent choices made in those semantics.

Basic Concepts of Profile Diagram. Profile diagram is basically an extensibility mechanism that allows you to extend and customize UML by adding new building blocks, creating new properties and specifying new semantics in order to make the language suitable to your specific problem domain.

The abstract syntax is provided as a model described in a subset of UML, consisting of a UML class diagram and a supporting natural language It develops and specifies a decompositional representation framework for verbal semantics that is based on the Unified Modeling Language (UML), the graphical The Semantics Checker can validate UML models created with the 8.02 template. However, it is only available as a macro inside Visio when the diagram was The subject of Semantics is sense. If one thing has something that is connected by sense to another thing, it is the semantic relationship. The static semantics is transformed into OWL DL by an algorithm, and the dynamic semantics is described by DL-Safe rules.

O-Slang Definition 2. Formal Definition Fig.2. Theory-based Translation However, to show that the translation from UML to the theory-based model was correct, we had to show that it preserved the semantics of the UML diagrams. Since no formal semantics had been established, we deﬁned our own. UML v 1.0, Semantics 1 1. INTRODUCTION This document presents the semantics of the Unified Modeling Language (UML). These semantics are specified using a formal textual description together with a metamodel describing the constituents of all well-formed models that may be represented in the UML, using the UML itself.
