An introduction to XML. By Mario Jeckle http://www.jeckle.de/vorlesung/xml/index.html#toc Official W3C Introduction to XML Schema. Nice to read. http://www.w3.org/TR/xmlschema-0/ The current XML Standard. http://www.w3.org/TR/REC-xml The current XML Schema Standard http://www.w3.org/XML/Schema#dev This document covers how XMI provides open interchange of application components and related business assets. The document describes how XMI enables open scenarios, reviews the relationship of the new XMI standard from the OMG, and shows how this leads to open solutions. The major features and examples of XMI technology will be presented. http://www-4.ibm.com/software/ad/standards/xmiwhite0399.pdf http://www.w3.org/TR/xmldsig-core/ The projects collects and publishes information about the various acronyms prevalent within the XML technology. We develop a XML language (formulated using W3Cs XML Schema accompanied with a plain english semantics description) to store, exchange, and process information about the various acronyms of the XML technology. These information include the expansion of the respective acronym together with textual background information about the technology behind. Additionally, web references to normative resources and optionally links to examples should also be included. Further, the project delivers a XSLT sheet allowing to transfer the XML coded acronym information into the input format suitable for the Babylon Translator. Hence, the project will also release the acronym information as pre-built Babylon glossary. Since there are so many XML related acronyms the targeted goal cannot be accomplished without external involvement. The project will therefore strongly encourage all interested parties to contribute. http://www.xml-acronym-demystifier.org http://cgi.omg.org/docs/ad/99-10-02.pdf http://cgi.omg.org/docs/ad/99-10-11.pdf (Open Document URL with "Save as.." function) http://www.jeckle.de/files/99-10-06.dtd (Open Document URL with "Save as.." function) http://www.jeckle.de/files/99-10-05.dtd http://cgi.omg.org/docs/ad/99-10-04.pdf http://cgi.omg.org/docs/ad/99-10-03.pdf http://cgi.omg.org/cgi-bin/doc?formal/02-01-01.pdf XML Metadata Interchange (XMI) version 1.1 http://cgi.omg.org/cgi-bin/doc?formal/00-11-02.pdf Die edition W3C.de hat die Veröffentlichung sämtlicher W3C-Empfehlungen (Recommendations) in deutscher Sprache und fachlicher Kommentierung zum Ziel.

But software to manage UML itself has a well-earned reputation for being inflexible and difficult. This article describes how the Danish development house Ideogramic ApS extended XMI (an XML specification targeted at such metadata as UML), and explores both the benefits and limitations of "XMLization." Source: IBM http://www-106.ibm.com/developerworks/library/x-xmi/?n-x-1111 by Jon Siegel http://www.omg.org by Dan Chang, Dan Harkey This exciting tour of emerging Web technologies explains what Java and XML offer for the future of the Internet. Early chapters discuss the current state of the Internet, including HTTP, followed by a quick tour of Java technologies. The authors look at database standards such as SQL (for relational databases) and the Object Data Management Group (ODMG) 2 standard (for object databases). The most hands-on part of this title examines how to implement a Web-based database using three different technologies: Java Database Connectivity (JDBC) for programming relational databases in Java; the emerging SQLJ standard for creating "embedded" SQL within Java code; and the ODMG Java binding for manipulating object-oriented databases directly in Java. Next, the authors look at providing HTML pages on the fly using Common Gateway Interface (CGI) and Java Servlets. Further sections introduce additional Java-based technologies, such as Remote Method Invocation (RMI), Java Object Request Brokers (ORBs), JavaBeans, and Enterprise JavaBeans. Later in the book, the authors explore the intricacies of the XML standard for structuring content within Web browsers. They also detail the Java classes that permit developers to program with XML today. The final chapter concentrates once more on the future tense, with a tour of other emerging standards and technologies. --Richard Dragan http://www.amazon.com/exec/obidos/ASIN/0471245771 by Timothy J. Grose, Gary C. Doney, Stephen A. Brodsky The authors cover the basics first, detailing the essential XML and UML concepts that you need to know to understand XMI. In addition to XMI fundamentals, they explain how XMI works with the Model Driven Architecture (MDA), a new software development approach. After learning how XMI works, you will then learn how to: Use XMI to express your object-oriented software models in XML Generate Java implementation classes from your models using the XMI Framework Create and read XMI documents in Java with standard XML APIs (DOM and SAX) and the XMI Framework Reverse engineer models from XML documents, DTDs, and schemas http://www.amazon.com/exec/obidos/ASIN/0471384291/103-9982552-8327025 seen in ZDNet eWeek http://www.zdnet.com/eweek/stories/general/0,11011,372873,00.html by Ann M.

Tools and methodologies are needed to cope with the evolution of software components. We present some basic concepts and architectures to handle the impacts of the evolution of UML models. With the proposed concepts a infrastructure to support model evolution, data schema migration, and data instance migration based on UML models can be realized. To describe the evolution path we use XML/XMI files. by Frank Keienburg, Andreas Rausch (Technische Universität München) http://wwwbroy.informatik.tu-muenchen.de/~rausch/publications/2001/HICSS.pdf http://cgi.omg.org/cgi-bin/doc?formal/00-06-01.pdf The goal of this work is to make UML "RDF-compatible". This allows mixing and extending UML models and the language elements of UML itself on the Web in an open manner. XMI, the current standard for encoding UML in XML by OMG, does not offer this capability. It is based upon a hard-wired DTD. For example, if a third party were to refine the concept "Event" defined in UML statecharts into say "ExternalEvent" and "InternalEvent", it would not be possible to serialize the corresponding event instances in XMI. http://www-db.stanford.edu/~melnik/rdf/uml/ XMI tutorial at UML2001. by Perdita Stevens http://www.dcs.ed.ac.uk/home/pxs/XMI/uml2001slides.pdf A Reference for the XMI based on based on XMI 1.1 DTD by Zvon http://www.zvon.org/xxl/XMI/Output/index.html Summary: Learn how the XMI Export download helps developers to access information from a Visio UML model by exporting it to an XML file. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvisio02/html/umlxmi.asp We demonstrate how XML and related technologies can be used for code mobility at any granularity, thus overcoming the restrictions of existing approaches. By not fixing a particular granularity for mobile code, we enable complete programs as well as individual lines of code to be sent across the network. We define the concept of incremental code mobility as the ability to migrate and add, remove, or replace code fragments (i.e., increments) in a remote program. The combination of fine-grained and incremental migration achieves a previously unavailable degree of flexibility. We examine the application of incremental and fine-grained code migration to a variety of domains, including user interface management, application management on mobile thin clients, for example PDAs, and management of distributed documents. by Wolfgang Emmerich Cecilia Mascolo Anthony Finkelstein http://doi.acm.org/10.1145/337180.337227 The tools and processes used to design XML vocabularies (DTD or XML Schema) are generally different from those used for application design using UML. In addition, large XML vocabularies are often difficult to understand and communicate with business users. This research summary describes the use of UML class diagrams for modeling XML vocabularies and generating XML Schemas from the UML. by David A. Carlson Ontogenics Corp. http://doi.acm.org/10.1145/367845.367982 As the use of XML matures within our systems development toolkit, we need a better approach for integrating its schema definitions with other analysis and design activities. The Unified Modeling Language (UML) is described as a useful solution that breaks down walls separating development activities and technologies. A financial derivatives trade application is described where the FpML vocabulary is imported into UML from its XML Schema source, and this is integrated with a Trading Party vocabulary imported from a SOX schema included in xCBL. These XML data definitions are then linked with a relational database schema imported into the same UML model. All of these data definitions are integrated as part of a simple portal application for trade confirmation. The iterative design approach illustrates benefits of UML for rapid analysis and design of new e-business applications that include XML content in part of their design. by David Carlson <dcarlson@ontogenics.com> http://www.xmlmodeling.com:80/articles/IntegratingXMLData.pdf by David Carlson, CTO Ontogenics Corp. dcarlson@ontogenics.com http://XMLmodeling.com http://www.xmlmodeling.com/articles/ModelingXML-Part1.pdf by David Carlson, CTO Ontogenics Corp. dcarlson@ontogenics.com http://XMLmodeling.com http://www.xml.com/pub/a/2001/09/19/uml.html by David Carlson, CTO Ontogenics Corp. dcarlson@ontogenics.com http://XMLmodeling.com http://www.xml.com/pub/a/2001/10/10/uml.html This document describes the first complete XML Schema for XHTML Basic, which was adopted as a W3C Recommendation in December 2000 [1]. The W3C Recommendation specifies XHTML Basic with a DTD implementation, principally because DTDs were the only recommendation in force at that time. However, we will soon reach a point when the W3C has two schema recommendations, and there are several other XML schema/validation languages that are competing for our attention (RELAX, TREX, and Schematron). Thus, a new approach was taken to produce the XML Schema described here: the XHTML Basic specification was manually reverse-engineered into a Unified Modeling Language (UML) class diagram, then the Schema was automatically generated from that UML model. Other schema languages can be produced in a similar manner; prototypes are under development for generation of DTD and RELAX. by Dave Carlson CTO Ontogenics Corp. Boulder, Colorado dcarlson@ontogenics.com http://XMLmodeling.com http://www.xmlmodeling.com/examples/xhtml/ModelingXHTML.pdf Create more powerful, flexible applications using a new extension of the XML standard Programmers are finding that the XMI extension of the XML standard provides a lot more flexibility in writing software for sharing data. Written by one of the principal authors of XMI, this book provides programmers with everything they need to know to best utilize this extension. The authors cover the basics first, detailing the essential concepts and explaining how XMI relates to XML and UML. Readers will then learn how to program with XMI, including how to express data in XMI, create XMI documents with Java, and merge documents. Samples of real-world XMI applications are also included throughout the book that show how IBM is using XMI with data warehousing and how to convert simple relational databases into XMI. http://www.amazon.com/exec/obidos/tg/detail/-/0471384291 We discuss how tools can be integrated even in the context of conflicting data models, and provide an architecture for doing so, based on component technology and XML Metadata Interchange. As an example, we discuss the implementation of an electronic whiteboard tool, Knight, which adds support for creative and collaborative object-oriented modelling to existing Computer-Aided Software Engineering through integration using our proposed architecture. by Christian Heide Damm, Klaus Marius Hansen, Michael Thomsen, Michael Tyrsted Department of Computer Science, University of Aarhus, Aabogade 34, 8200 Aarhus N, Denmark Email: {damm, marius, miksen, tyrsted}@daimi.au.dk http://www.cit.dk/COT/reports/reports/Case2/49/cot-2-49.pdf An XPath functions reference.

For a more complete description of all the features of EMF, refer to the EMF Users Guide or to the JavaDoc for the framework classes themselves. http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E/emf-home/docs/overview.html This tutorial is a step-by-step description of the process of creating an EMF model and generating a simple model editor for it. Following this tutorial will show how easy EMF makes it to go from a simple model definition to a fully functioning editor for that model. http://dev.eclipse.org/viewcvs/indextools.cgi/%7Echeckout%7E/emf-home/docs/clibmod/clibmod_main.html The eXtensible Markup Language (XML) and its related technologies provide a promising tool for the implementation of transformations of UML models, not only for research prototypes but also for the interaction of different commercial CASE tools. We report on our experiments with XML query and transformation languages in the context of object-oriented software development. Especially we use the XML Metadata Interchange Format (XMI) as a tool for the transformation of object-oriented models. We outline XMI based scenarios in the forward and reverse engineering of different applications. As an example, we show how XMI and a standardized XML query/transformation language such as XSLT can be used for the generation of SQL database schemas based on UML models, and for design recovery from legacy code. by Demuth, Hussmann, Obermaier http://ase.arc.nasa.gov/wtuml01/submissions/demuth-hussman-obermaier.pdf Benoît discusses the motivations for modeling XML schema through the use of UML. He also introduces XML Metadata Interchange (XMI) and sketches out a strategy for deriving XML schemas automatically from UML models. by Benoît Marchal (bmarchal@pineapplesoft.com) http://www-106.ibm.com/developerworks/xml/library/x-wxxm23/ In the second part of this series on UML and XML, Benoît introduces the UML metamodel. He proceeds to XMI, the XML-based specification for the exchange of models. He then shows how to map from the metamodel to XML schema. As an illustration, he includes two stylesheets that provide simple round-trip engineering between UML and XML. by Benoît Marchal (bmarchal@pineapplesoft.com) http://www-106.ibm.com/developerworks/library/x-wxxm24/ http://www.omg.org/cgi-bin/doc?formal/2003-05-02 by David S.
