Web-based systems now play increasingly important roles in many applications. As we now rely heavily on them, there is pressing need for improved quality, performance and availability of these systems. However, most Web-based systems are still poorly developed and in an ad hoc manner. Hence, they perform poorly, do not scale up and are prone to failures.
Web engineering is a proactive approach that addresses these concerns and offers systematic approaches and disciplined processes for development of large, complex Web-based systems and applications.
The tutorial will discuss problems facing Web application development and introduce the rapidly emerging field of Web engineering. It is specifically targeted to address the needs of growing community of Web application developers, IT and business professionals, E-Commerce system implementers, project managers. General understanding of Web page and site development, and also of general application development and/or software engineering are desirable.
The tutorial will:
The participants are advised to attend the follow-on tutorial TP1, Managing the Growth, Maintainability and Quality of Web Applications: The Web Engineering Approach, which will focus on scalability, maintainability, testing, quality assurance, design considerations and Web project management.

Web services have been gathering much attention lately in the industry, from researchers, and even in the press. Everyone agrees about their fundamental importance to information technology architectures and applications.
The main advantage of web services arises when we can compose them to create new services. Unfortunately, much of the attention on web services has been focused on the lower-level, infrastructural matters, often down to encoding syntaxes and unnecessarily narrow means of invoking services. For web services to be effectively composed requires an understanding of deeper concepts. These concepts have been developed in diverse parts of computer science, especially, heterogeneous databases, distributed computing, artificial intelligence, and multiagent systems.
This tutorial will present the necessary concepts, architectures, theories, techniques, and infrastructure to compose web services. It will include a comprehensive overview of the state of the art in selected application areas. This tutorial gives the essential background for anyone planning to learn about and contribute to the principles and applications of service composition. It will guide practitioners by highlighting best practices in service composition and introduce students and advanced developers to the key trade-offs as well as the limitations of current approaches.
The major sections of this tutorial will include:
The tutorial has a sequel, TP2 - Service Composition Techniques, which discusses techniques and best practices for service composition.

The functionality of Web applications as well as their performance and quality needs grow very rapidly. Further, the content management is another daunting and challenging task. The way we address these needs is critical for successful development, implementation and ongoing maintenance of Web applications. Web-based systems need to be designed and built for scalability, maintainability, high performance and reliability; these features can't be added later. The Web system developers play major role in ensuring the quality, reliability and robustness of e-business systems, and thereby in increasing the users' confidence on the system.
This tutorial will address these needs, discuss how to successfully manage the growth, maintainability, quality of Web applications, and provide insights on Web project management. Web application developers, IT and business professionals, E-Commerce system implementers and project managers would find the tutorial very useful. General understanding of Web page and site development, and also of general application development and/or software engineering is desirable.
The tutorial will:
Participants are encouraged to attend the tutorial TA1, Meeting the Challenges of Web Applications Development: The Web Engineering Approach, to get a better insight into the challenges of Web development and the foundations of Web Engineering.

This research group collaborates with several other groups across the world engaged in this emerging field.
This tutorial has a companion "prequel" tutorial, TA2 - Web Service Composition, which emphasizes service composition concepts. Attendees with sufficient background may skip the prequel.
Some of the key techniques for service composition (e.g., dealing with their discovery and engagement) were developed in the areas of databases, distributed computing, artificial intelligence, and multiagent systems. These are generally established bodies of work that can be readily adapted for service composition. Some additional techniques, although inspired by these areas, must be developed from scratch, because they address the essential openness and scale of web applications that previous work did not need to address. Both classes of key techniques should be incorporated into our best practices for service design and composition. In many cases, they can be applied on top of the existing approaches.
This tutorial seeks to explain the true purposes of service composition, to evaluate existing approaches, and to present existing techniques from other areas that can be adopted for service composition, and lastly to introduce emerging techniques for addressing challenges that are unique to service composition.
This tutorial is presented at a beginning graduate student level. We expect it to be accessible to web programmers, advanced developers, and students.

Until recently, the way to add schematic drawings to a web page was to define the drawing as an image (in GIF, PNG, JPEG or some other format) and insert the image into the web page using the <IMG> element. This has the following major drawbacks:
Scalable Vector Graphics, or SVG, is the World Wide Web Consortium's Recommendation for defining 2-dimensional schematic drawings such that the size is more directly dependent on the content in the drawing and the resolution is whatever the user requires. Zooming in on an SVG drawing allows greater and greater detail to be seen if the drawing is complex.
This tutorial will include SVG attributes for:

Security is a vital pre-requisite to development of many Web Services. The lack of a security infrastructure is one of the most commonly voiced objections to deployment of web Services.
The aim of this tutorial is to provide participants with a roadmap of Web Services security, including both techniques with which to secure Web services and security services that are packaged as Web services. This course will cover all the W3C and OASIS security standards currently in process and proposals that are on the horizon but not yet in process.
It is the intention that this tutorial be a 'state of the art' presentation covering the most up to the minute breaking developments. The presenter is in constant communication with all the people who are currently defining the 'state of the art'.
Some familliarity with Web services concepts is desirable.

This tutorial introduces quantitative performance predictive models for every major Web scenario, showing precisely how to identify and address both potential and actual performance problems. It provides a quantitative framework for planning the capacity of Web services and understanding their behavior.
The tutorial focuses on two main topics. It presents an integrated capacity planning methodology that covers benchmarking, load testing, workload forecasting, and performance modeling of Web services. It shows how to perform a quantitative analysis of Web service availability. The tutorial presents many examples and case studies that show how to use each technique in problems related to portals, search engines, e-business, and mobile and streaming-media applications.

As Web applications manipulate an increasing amount of XML data, there is growing interest on how to manage this data. Because XML is extensible and flexible, it can be used in applications with radically differing needs. This flexibility also implies that one cannot expect to find out-of-the-box solutions for all different applications; given the scope of the problem, the immaturity of existing tools, and the evolving standards environment, building these solutions is a challenging task.
The objective of this tutorial is to give an overview of XML data management, presenting both the major issues involved in managing such data and solutions for them. Topics covered in this tutorial include: storing, querying, updating, and publishing XML data. Special emphasis will be given to concrete techniques for developers, making clear how properties of an application area influence the solution.

SMIL 2.0 specifies interactive multimedia on the Web. It has just been released as a W3C recommendation. It already enjoys substantial support, implemented in such Web browsers as RealNetworks' RealOne and Internet Explorer 6.0. This version of SMIL extends SMIL 1.0, a W3C recommendation since June 1998. SMIL 2.0 is 15 times as large as SMIL 1.0, and defines a family of languages rather than just one language. This tutorial presents SMIL 2.0, tools for it, how to create presentations in it, and how it has currently been adopted by the community at large.
The goal of the tutorial is to explain the concepts that form the basis of the SMIL language and to provide sufficient detail on the language itself so that participants can create their own simple presentations. Participants will also understand the underlying issues of temporal and spatial layout and the complexity of creating links within multimedia. They will also be able to use available tools to play and create SMIL presentations.
Before describing the details of the SMIL 2.0 language, the tutorial first presents an overview of the components required in a hypermedia document description language. The SMIL language includes features for specifying the media items included in a document, referred to with URL's, how these are temporally and spatially related to one another, and how links can be specified within the multimedia environment. Alternates for different data formats for the heterogeneous web environment are also provided.
The tutorial is intended for content developers who have created HTML documents or have used tools such as Macromedia Director or Authorware. Multimedia designers, web-page creators, creators of interface prototypes such as user interface designers, human factors practitioners and industrial designers will also benefit from this course.
Presenter:
Lloyd Rutledge is a researcher at CWI, the Dutch national center for computer and mathematics research. His research involves adaptable hypermedia, and standards for it such as SMIL. He received his Sc.D. from the University of Massachusetts Lowell, where he worked with the Distributed Multimedia Systems Laboratory (DMSL) on developing the HyOctane HyTime-based hypermedia environment.
Dr. Rutledge is a member of the W3C working group that developed SMIL.
He is also co-author of "SMIL: Interactive Multimedia on the Web", to
be published in May by Pearson Education.
Topic maps are a new ISO standard providing a powerful paradigm and an XML-based exchange syntax for the organisation and navigation of large and continuously growing amounts of information, like the Web. Topic maps are - together with RDF - a base technology of the Semantic Web and numerous other application domains dealing with the challenges of info-glut.
The tutorial will provide the delegates with substantial knowledge about topic maps, their concepts, the differences to RDF, and their applications, and how to develop them. Furthermore, a workshop-like interactive creation of an example topic map will make the tutorial very valuable for the attendees. At the end of the day, the participants learned how to apply topic maps to their own information resources and are able to use topic maps with the freely distributed software.
The tutorial is divided in six parts:
Parts II and III close with intensive exercises giving the attendees the opportunity to create together supported by course instructor their own topic map.
Basic XML knowledge is helpful, but not necessary. The delegates should have an understanding of the information resources their companies are working with to contribute to and to benefit from the topic map creation during the tutorial.

Workshop Web site: http://semanticweb2002.aifb.uni-karlsruhe.de/
The "Semantic Web" is used to denote the next evolution step of the Web, which establishes a layer of machine understandable data. The data is suitable for automated agents, sophisticated search engines and interoperability services, which provide a previously not reachable grade of automation. The ultimate goal of the Semantic Web is to allow machines the sharing and exploitation of knowledge in the Web way, i.e. without central authority, with few basic rules, in a scalable, adaptable, extensible manner.
Relevant workshop topics include but are not limited to:
The Workshop gives the attendants the possibility to discuss ideas, problems and visions in depth and face to face. The objective of the workshop is to bring researchers and developers of the Semantic Web together not only to represent mature work, but also to discuss the ongoing development in order to allow for smoother and faster progression of the Semantic Web. We plan to limit the number of formal presentations and concentrate on discussion sessions instead.
Facilitators:

Workshop Web site: http://www.haifa.il.ibm.com/Workshops/www2002-MobileSearch/
The dramatic increase in the use and availability of mobile devices such as cellular phones and Personal Digital Assistants (PDAs) in the last few years has resulted in the ability to access information anytime and anywhere. IDC, a leading provider of technology intelligence, forecasts that by the end of 2002 there will be more wireless subscribers capable of Internet access than wired Internet users. Yet, we are still far from realizing the dream of having Web information as conveniently accessible from a handheld device as it is from our desktop. Existing information discovery mechanisms for searching and browsing the Web are not well suited to mobile devices, which are limited in terms of processing power and memory, screen real estate, input capabilities, networks and bandwidth.
In this workshop, we will explore several issues involved in making mobile search both practical and effective, and investigate the various challenges imposed in attempting to bring search to the mobile world. Topics may include:

Workshop Web Site: http://www.dcs.bbk.ac.uk/webDyn2/
The World-Wide-Web is of strategic importance as a global repository for information and a means of communicating knowledge. Since the first Web Dynamics Workshop held in January 2001, there has been a continuous deployment of novel technologies to cope with dynamic change within the Web, and a rise of new technologies to address new challenges. Examples of the former are the success of search engine technology in delivering up-to-date information and the realisation of the importance of security-related issues, and an example of the latter is the semantic Web which is aiming to facilitate interaction with the Web through automated Web services.
The aim of this second Web Dynamics Workshop is to bring together researchers from academia and industry who are working on novel approaches to managing and interacting with the Web. In particular, there is a need to understand and manage the dynamics of the Web - how its information content, topology, and usage change, and what kinds of models and techniques will scale up to the rate of change.
The topics of interest of the workshop include, but are not restricted to, the following list:

The Web continues to have an enormous and constantly changing impact on learning and education. The use of the Web to deliver teaching/training materials is now commonplace but there is an ever increasing need for the development of e-learning standards. Much of the basic content used in courses around the world is similar (ie Algebra and Accounting 101) and many are recognising the expense and time being wasted "re-inventing the wheel"
The focus of this workshop will be on developing re-usable learning objects, best practice, standards and copyright/IP issues of sharing generic content. Subject to the position papers received, the workshop will focus on many or all of the following topics:
Registration for the workshop will be subject to the submission of a position paper which should describe the participants' experince with e-learning and their hopes and expectations for the workshop. The call for position papers, the position papers themselves and a report of the workshop will all be made available on the workshop web site.

The Resource Description Framework (RDF) is the World Wide Web Consortium's specification for defining machine-understandable metadata. In the long term, we expect that RDF in conjunction with other standards such as WSDL, SOAP, UDDI and XML will serve as the foundation for Semantic Web applications. However, it is possible to take immediate advantage of the various standards by using RDF models in conjunction with them for building advanced Web services.
The objective of this workshop is to discuss commercial applications that make immediate advances and to gain insight into the evolution of the semantic web technology. Early commercial applications that make use of machine-understandable metadata range from information retrieval to Web-enabling of old-tech IBM 3270 sessions. Current developments include metadata-based Enterprise Application Integration (EAI) systems, data modeling solutions, and wireless applications. Machine-understandable metadata is emerging as a new foundation for component-based approaches to application development. Within the context of reusable distributed components, Web services represent the latest architectural advancement.
We invite submissions that discuss real applications (piloted, deployed, robust prototypes) attacking real world problems in the Semantic Web arena today instead of the future. This potentially means very pragmatic decisions (e.g., executable agents that run in the context of graph-based application models) caused by the limitations of today's technology (e.g., are there robust/scalable RDF parsers, stores, and inference engines?). Submissions that also address issues related to the business aspects, e.g., is there a market ?, is there a sustainable value proposition ?, what is the business model, etc., will receive special consideration. Some topics are:
