The step-by-step guide to creating program generators with Java and XML. Breakthrough Java/XML techniques for creating program generators, including detailed examples and real-world guidelines Domain engineering techniques for improving software development productivity CD-ROM with examples, working code, and relevant XML specifications "XML isn't just for data any more. Now you can use XML to describe the programs you need, then write a Java program template to generate them automatically. This book shows you how." --Charles F. Goldfarb Using Java and XML, you can now easily create "wizard-like" program generators that automate much of the work of software development(and deliver significant productivity improvements. In this book, former Bell Laboratories Distinguished Staff Member J. Craig Cleaveland shows you how to do it. Using extensive practical examples, "Program Generators with XML and Java" walks you through every step: Identifying off-the-shelf tools for quickly building program generators Domain Analysis: determining the terminology, boundaries, commonalities, and variabilities of software families Domain Implementation: processes and tools for efficiently generating customized software Accounting for run-time and compile-time variabilities Using XML documents as program specifications, and using the DOM and SAX APIs to read and analyze them Using JavaServer Pages and XPath/XSLT to generate customized software The role of reusable architectures and components, including JavaBeans Chances are, you're already using automated GUI builders, database application generators, and other code generation "wizards." Now, with "Program Generators with XML and Java," you canextend the advantages of code generation throughout your own custom applications and get to market faster, with greater reliability and lower costs.

Automatic code generation is an essential cornerstone of model-driven approaches to software development. Currently, lots of techniques are available that support the specification and implementation of code generators, such as engines based on templates or rule-based transformations. All those techniques have in common that code generators are either directly programmed or described by means of textual specifications. This monograph presents Genesys, a general approach, which advocates the graphical development of code generators for arbitrary source and target languages, on the basis of models and services. In particular, it is designed to support incremental language development on arbitrary metalevels. The use of models allows building code generators in a truly platform-independent and domain-specific way. Furthermore, models are amenable to formal verification methods such as model checking, which increase the reliability and robustness of the code generators. Services enable the reuse and integration of existing code generation frameworks and tools regardless of their complexity, and at the same time manifest as easy-to-use building blocks which facilitate agile development through quick interchangeability. Both, models and services, are reusable and thus form a growing repository for the fast creation and evolution of code generators.

As a result of the open-source movement there is now a great deal of reusable software available in the public domain. This offers significant functionality that commercial software vendors can use in their software projects. Open-source approaches to software development have illustrated that complex, mission critical software can be developed by distributed teams of developers sharing a common goal. Commercial software vendors have an opportunity to both learn from the op- source community as well as leverage that knowledge for the benefit of its commercial clients. Nonetheless, the open-source movement is a diverse collection of ideas, knowledge, techniques, and solutions. As a result, it is far from clear how these approaches should be applied to commercial software engineering. This paper has looked at many of the dimensions of the open-source movement, and provided an analysis of the different opportunities available to commercial software vendors. References and Notes 1. It can be argued that the open-source community has produced really only two essential 9 products -- Apache (undeniably the most popular web server) and Linux although both are essentially reincarnations of prior systems. Both are also somewhat products of their times: Apache filled a hole in the then emerging Web, at a time no platform vendor really knew how to step in, and Linux filled a hole in the fragmented Unix market, colored by the community s general anger against Microsoft. 2.Evans Marketing Services, Linux Developers Survey, Volume 1, March 2000.

The emerging Second-Generation Web is based entirely on XML and related technologies. It is intended to result in the creation of the Semantic Web, on which computers will be able to deal with the meaning ("semantics") of Web data and hence to process them in a more effective and autono mous way. This new version of the Web introduces a multitude of novel concepts, terms, and acronyms. Purpose, Scope and Methods This dictionary is an effort to specify the terminological basis of emerging XML and Semantic Web technologies. The ultimate goal of this dictionary is even broader than just to define the meaning of newwords - itaims to develop aproper understandingofthese leading-edge technologies. To achieve this, comprehensible definitions of technical terms are supported by numerous diagrams and code snippets, clearly annotated and explained. The main areas covered in this dictionary are: (1) XML syntax and core technologies, such as Namespaces, Infoset and XML Schema; (2) all the major membersofthe XML family oftechnologies, such as XSLT, XPath and XLink; (3) numerous XML-based domain-specific languages, such as NewsML (News Markup Language); (4) the concept and architecture of the Semantic Web; (5) key Semantic Web technologies,such as RDF (Resource Description Framework), RDF Schema and OWL (Web Ontology Language); and (6) Web services, including WSDL (Web Services Description Lan guage) and SOAP (Simple Object Access Protocol).

Model-Driven Software Development (MDSD) is currently a highly regarded development paradigm among developers and researchers. With the advent of OMG's MDA and Microsoft's Software Factories, the MDSD approach has moved to the centre of the programmer's attention, becoming the focus of conferences such as OOPSLA, JAOO and OOP. MDSD is about using domain-specific languages to create models that express application structure or behaviour in an efficient and domain-specific way. These models are subsequently transformed into executable code by a sequence of model transformations. This practical guide for software architects and developers is peppered with practical examples and extensive case studies. International experts deliver: * A comprehensive overview of MDSD and how it relates to industry standards such as MDA and Software Factories. * Technical details on meta modeling, DSL construction, model-to-model and model-to-code transformations, and software architecture. * Invaluable insight into the software development process, plus engineering issues such as versioning, testing and product line engineering. * Essential management knowledge covering economic and organizational topics, from a global perspective.

This volume constitutes the proceedings of the second International Conference on Generative Programming and Component Engineering (GPCE 2003), held September 22–25, 2003, in Erfurt, Germany, sponsored by the NetObjectDays German industrial software development event, in cooperation with the ACM SIGPLAN and SIGSOFT societies. GPCE was created as an e?ort to bring - getherresearchersworkingonboththeprogramminglanguagesandthesoftware engineeringsideofprogramgenerationandcomponentengineering. Thecommon theme of program generation and component engineering is the domain-speci?c nature of both approaches. Depending on the characteristics of a domain, either a generative or a compositional technical solution may be appropriate. In just its second year, GPCE has shown a lot of promise for building a strong community. The response to the call for papers was excellent, with 62 submissions to the technical program, 2 of which were later withdrawn. Each paper received between three and ?ve reviews, many of them quite thorough and hopefully valuable to all authors. The electronic meeting allowed for - depthdiscussionsofallsubmissions,oftentoamuchgreaterextentthanpossible in a physical PC meeting. As a result, 21 papers were selected for presentation at the conference and are included in this volume, together with abstracts for the invited talks by Olivier Danvy and Peri Tarr. Of the accepted papers, 3 are co-authored by PC members (from a total of 5 PC submissions). We tried hard to ensure fairness and hold PC submissions to a high standard. The EDAS conference submission system was used to manage the paper submissions. Our EDAS installation was supported by Blair MacIntyre, who was particularlyhelpfulinresolvingtechnicalissueswiththesystem.
