Introduction 1.1 Intent of this document The modeling guide for Cameo NIEM-UML provides modelers, information architects and developers with the information they need to develop, maintain and leverage UML for information sharing based on the National Exchange Model (NIEM). Cameo NIEM-UML is based on the NIEM-UML standard (in final stages of adoption) of the Object Management Group (OMG). This guide is intended to support modeling for NIEM, it is not a tutorial on either NIEM or UML. Background information can be found in the following resources: • NIEM: https://www.niem.gov/about/tech/Pages/technical-overview.aspx • NIEM-UML: http://www.niem-uml.org • UML Training: http://www.nomagic.com/services/training.html • UML Resources: http://www.uml.org/ • Magicdraw: http://www.magicdraw.com 1.2 NIEM-UML Background Grown out of a grassroots initiative, the National Information Exchange Model (NIEM) was born as a best practice developed by a handful of state and local practitioners and defined in NIEM’s predecessor, the Global Justice XML Data Model (GJXDM). Today, NIEM is a national program that empowers organizations to create and maintain meaningful data connections across their stove-piped IT systems, as well as their stakeholder base. NIEM provides data components and processes needed to create exchange specifications which support mission data sharing and exchange requirements. By providing a common vocabulary and mature framework to facilitate information exchange, NIEM enables communities to “speak the same language” as they share, exchange, accept, and translate information efficiently. Traditionaly NIEM has been defined in terms of the eXtensible Markup Language (XML), XML Schema (XSD) and the normative NIEM platform specifications which include the NIEM Naming and Design Rules (NDR) Version 1.3 and the NIEM Model Package Description (MPD) Specification Version 1.0. These platform specifications are utilized without change in NIEM-UML and the NIEM-UML specification

Störrle, Dr. A. Knapp UML 2.0 – Tutorial (v4) 2 1 - Introduction History and Predecessors • The UML is the “lingua franca” of software engineering. • It subsumes, integrates and consolidates most predecessors. • Through the network effect, UML has a much broader spread and much better support (tools, books, trainings etc.) than other notations. • The transition from UML 1.x to UML 2.0 has – resolved a great number of issues; – introduced many new concepts and notations (often feebly defined); – overhauled and improved the internal structure completely. • While UML 2.0 still has many problems, current version (“the standard”) it is much better than what we ever had formal/05-07-04 of August ‘05 before.

  • Sysml Distilled: a Brief Guide to the Systems Modeling Language
    ptg11539604 Praise for SysML Distilled “In keeping with the outstanding tradition of Addison-Wesley’s techni- cal publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engi- neers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distin- guishing the subtle differences between use cases and scenarios to illu- mination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” — Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disci- plines and across the development life cycle. Many languages have the ptg11539604 potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many do- mains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” — Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML.

  • UML Basics: the Component Diagram
    English Sign in (or register) Technical topics Evaluation software Community Events UML basics: The component diagram Donald Bell ([email protected]), IT Architect, IBM Corporation Summary: from The Rational Edge: This article introduces the component diagram, a structure diagram within the new Unified Modeling Language 2.0 specification. Date: 15 Dec 2004 Level: Introductory Also available in: Chinese Vietnamese Activity: 259392 views Comments: 3 (View | Add comment - Sign in) Average rating (629 votes) Rate this article This is the next installment in a series of articles about the essential diagrams used within the Unified Modeling Language, or UML. In my previous article on the UML's class diagram, (The Rational Edge, September 2004), I described how the class diagram's notation set is the basis for all UML 2's structure diagrams. Continuing down the track of UML 2 structure diagrams, this article introduces the component diagram. The diagram's purpose The component diagram's main purpose is to show the structural relationships between the components of a system. In UML 1.1, a component represented implementation items, such as files and executables. Unfortunately, this conflicted with the more common use of the term component," which refers to things such as COM components. Over time and across successive releases of UML, the original UML meaning of components was mostly lost. UML 2 officially changes the essential meaning of the component concept; in UML 2, components are considered autonomous, encapsulated units within a system or subsystem that provide one or more interfaces. Although the UML 2 specification does not strictly state it, components are larger design units that represent things that will typically be implemented using replaceable" modules.

  • The Validation Possibility of Topological Functioning Model Using the Cameo Simulation Toolkit
    The Validation Possibility of Topological Functioning Model using the Cameo Simulation Toolkit Viktoria Ovchinnikova and Erika Nazaruka Department of Applied Computer Science, Riga Technical University, Setas Street 1, Riga, Latvia Keywords: Topological Functioning Model, Execution Model, Foundational UML, UML Activity Diagram. Abstract: According to requirements provided by customers, the description of to-be functionality of software systems needs to be provided at the beginning of the software development process. Documentation and functionality of this system can be displayed as the Topological Functioning Model (TFM) in the form of a graph. The TFM must be correctly and traceably validated, according to customer’s requirements and verified, according to TFM construction rules. It is necessary for avoidance of mistakes in the early stage of development. Mistakes are a risk that can bring losses of resources or financial problems. The hypothesis of this research is that the TFM can be validated during this simulation of execution of the UML activity diagram. Cameo Simulation Toolkit from NoMagic is used to supplement UML activity diagram with execution and allows to simulate this execution, providing validation and verification of the diagram. In this research an example of TFM is created from the software system description. The obtained TFM is manually transformed to the UML activity diagram. The execution of actions of UML activity diagrams was manually implemented which allows the automatic simulation of the model. It helps to follow the traceability of objects and check the correctness of relationships between actions. 1 INTRODUCTION It represents the full scenario of system functionality and its relationships. Development of the software system is a complex The simulation of models can help to see some and stepwise process.

    Department of the Navy XML Naming and Design Rules Office of the DON Final Version 2.0 Chief Information Officer January 2005 Department of the Navy XML Naming and Design Rules January 2005 18 January 2005 MEMORANDUM FOR DISTRIBUTION Subj: EXTENSIBLE MARKUP LANGUAGE (XML) NAMING AND DESIGN RULES OFFICIAL RELEASE To comply with joint requirements as embodied in the DoD Net-Centric Data Strategy and to achieve the FORCEnet requirement for a common structure and language for information handling, the Department of the Navy (DON) is issuing Naming and Design Rules (NDR) that facilitate the discovery and use of common data across the naval enterprise. XML, an open standards based technology, is a key enabler of the Department's net-centric data strategy. The NDR provides additional rigor necessary to efficiently and effectively operate in a net-centric data-sharing environment. These rules move the DON forward to ensure that all XML is based on a consistent set of schema through the application of open standards that align with the Federal Enterprise Architecture Data Reference Model and Global Information Grid. The result will be an environment that is sustainable, responsive, and agile. The NDR is the product of expertise and energies contributed by representatives from 13 key Navy, Marine Corps, and Secretary of the Navy organizations who participated in the DON XML Working Group. To ensure these rules are applicable and current, the DON Chief Information Officer (DON CIO) has established the XML Business Standards Council and is proceeding to charter the Net-Centric Technical Standards Council to serve as liaison to organizations developing national and international standards for XML and Web Services technologies.

  • A Learning Classifier System Approach
    The Detection and Characterization of Epistasis and Heterogeneity: A Learning Classifier System Approach A Thesis Submitted to the Faculty in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Genetics by Ryan John Urbanowicz DARTMOUTH COLLEGE Hanover, New Hampshire March 2012 Examining Committee: Professor Jason H. Moore (chair) Professor Michael L. Whitfield Professor Margaret J. Eppstein Professor Robert H. Gross Professor Tricia A. Thornton-Wells Brian W. Pogue, Ph.D. Dean of Graduate Studies c 2012 - Ryan John Urbanowicz All rights reserved. Abstract As the ubiquitous complexity of common disease has become apparent, so has the need for novel tools and strategies that can accommodate complex patterns of association. In particular, the analytic challenges posed by the phenomena known as epistasis and heterogeneity have been largely ignored due to the inherent difficulty of approaching multifactor non-linear relationships. The term epistasis refers to an interaction effect between factors contributing to diesease risk. Heterogeneity refers to the occurrence of similar or identical phenotypes by means of independent con- tributing factors. Here we focus on the concurrent occurrence of these phenomena as they are likely to appear in studies of common complex disease. In order to ad- dress the unique demands of heterogeneity we break from the traditional paradigm of epidemiological modeling wherein the objective is the identification of a single best model describing factors contributing to disease risk. Here we develop, evaluate, and apply a learning classifier system (LCS) algorithm to the identification, modeling, and characterization of susceptibility factors in the concurrent presence of heterogeneity and epistasis.
