On Refining XML Artifacts

2008

This paper outlines an approach to XML-based software development. According to this method, applications are described using domain specific, XML based, markup languages. With these languages we structure a set of XML documents that are subsequently processed to yield the executable application. The approach also makes an explicit distinction between contents documents and documents describing other application aspects (e.g. interaction, presentation and process). Using a software process model based on markup languages and documents we obtain some benefits such as an important code reuse and a significant maintenance improvement. This paper describes our experiences applying this approach in the hypermedia domain and in the development of an application framework for supporting a broader range of information-based applications.

We discuss three well-known languages for querying and manipulating XML documents: XQuery, XPath and XSLT. They are considered to be the standard languages for processing XML documents. However, specifying their complete semantics in a formal way seems almost impossible. Indeed, an attempt by the W3C XML Query Working Group to do so for XQuery was ultimately abandoned. We introduce three sublanguages, called MiXPath, MiXQuery and MiXSLT, and describe their syntax and formal semantics. The syntax and semantics of these languages are chosen such that they are consistent with the ones given in the related W3C recommendations. As such this provides a practical foundation for research and teaching of XML languages. For this purpose the sublanguages are chosen such that they contain the most crucial features, constructs and expressions of each of these three languages.

The increasing growth in size and complexity of web applications requires a systematic way to web application development that is able to incorporate the stringent demands imposed on both the development and maintenance of these systems. In the past a common strategy to alleviate these problems has been modularization. This paper outlines distinct initiatives within the XML research that attempt to present alternatives for accomplishing modularization at distinct levels of a Web application. The initiatives compared in this paper include XLink, the Web Composition Markup Language, the Web Object Composition Model and the Interactive Web Service endeavour, and they are presented together with examples.

Semantic web researchers tend to assume that XML Schema and OWL-S are the correct means for representing the types, structure, and semantics of XML data used for documents and interchange between programs and services. These technologies separate information representation from implementation. The separation may seem like a benefit, because it is platform-agnostic. The problem is that the separation interferes with writing correct programs for practical document engineering, because it violates a primary principle of object-oriented programming: integration of data structures and algorithms. We develop an XML binding framework that connects Java object declarations with serialized XML representation. A basis of the framework is a metalanguage, embedded in Java object and field declarations, designed to be particularly concise, to facilitate the authoring and maintenance of programs that generate and manipulate XML documents. The framework serves as the foundation for a layered software architecture that includes meta-metadata descriptions for multimedia information extraction, modeling, and visualization; Lightweight Semantic Distributed Computing Services; interaction logging services; and a user studies framework.

Abstract: Our research goal is the generation of working web applications from high level specifications. Based on our experience in using XML transformations for that purpose, we applied this approach to the rapid development of database management applications. The result is an architecture that defines of a web application as a set of XML transformations, and generates these transformations using second order transformations from a database schema.

The eXtensible Markup Language-XML-is not only a language for communication between humans and the web, it is also a language for communication between programs. Rather than passing parameters, programs can pass documents from one to another, containing not only pure data, but control information as well. Even legacy programs written in ancient languages such as COBOL and PL/I can be adapted by means of interface reengineering to process and to generate XML documents. This paper intends to describe the process and the tools required to accomplish that goal and to present three cases-one for online, one for batch and one for subprograms-to illustrate how XML may be used to integrate existing software systems into the web.

XML has crossed the borders of software engineering and has spread to other areas such as e-commerce, identification, information storage, instant messaging and others. It is used to communicate crucial data over these domains. Thus, allowing non-expert programmers to manipulate and control their XML data is essential. In the literature, this issue has been dealt with from 3 perspectives: (i) XML alteration/adaptation techniques requiring a certain level of expertise to be implemented and are not unified yet, (ii) mashups, which are not formally defined yet and are not specific to XML data, and (iii) XML-oriented visual languages based on structural transformations and data extraction mainly and not allowing XML textual data manipulations. In this paper, we discuss existing approaches and present our XA2C framework intended for both non-expert and expert programmers able to provide them with means to write/draw their XML data manipulation operations. The framework is designed in the combined spirits of both mashups and XML-oriented visual languages by defining a well-founded modular architecture similar to mashups and an XML-oriented visual functional composition language based on colored petri nets. The framework takes advantage of existing XML alteration/adaptation techniques by defining them as XML-oriented manipulation functions. A prototype called XA2C is developed and presented here with the set of tests conducted to validate our approach.

This article presents XML-based tools for parser generation and data binding generation. The underlying concept is that of transformation between formal languages, which is a form of meta-programming. We discuss the benefits of such a declarative approach with well-defined semantics: productivity, maintainability, verifiability, performance and safety.

Extensible Markup Language (XML) is a meta-language for defining new languages. Its impact on the modern and emerging web technologies has been (and will be) incredible and it has represented the foundation of a multitude of applications. This chapter is devoted to the presentation of XML and its applications. It provides an introduction to this wide topic, covering the principal arguments and providing references and examples
