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

Using UML, it introduces basic modeling concepts in a highly precise manner, while The topics covered include not only the syntax and the semantics of the stereotypes to improve comprehension of UML models: A set of experiments brand an existing model element with specific semantics, but stereotypes can The grounds are that the UML does not define the correct semantics to be able to visualize a web application correctly.

We provide a rigorous semantics for one of the central diagram types which are used in UML for the description of dynamical system behavior, namely activity diagrams. We resolve for these diagrams some of the ambiguities which arise from difierent interpretations of UML models. Since we phrase our definition in terms of Abstract State Machines, we define at the same time an interesting

We compare our semantics with other semantics for UML activ-ity diagrams and workﬂow modelling by analysing the diﬀerent choices made in those semantics. 2021-02-01 Semantics of UML: P.H.Schmitt. UML and its Meaning. Winter 2002/2003; Kevin Lano, editor. UML 2 - Semantics and Applications.

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.

2.1.2 Approach This section emphasizes language architecture and formal rigor. The architecture of the UML is based on a four-layer metamodel structure, which consists of the following layers: user objects, model, metamodel, and meta Given a formal deﬁnition of UML’s semantics in the above framework, the semantics of a model is deﬁned as follows. Deﬁnition 1.1 (Descriptive semantics of a model) The descriptive semanticsofa model M under the hypothesis H is [[M]] H = AxmD ∪T(M)∪H(M).
