Enabling Technologies for the Future of Voice-Based Web Access

Session chair:
Scott R. Tilley,
University of California, Riverside, USA

Steve Woods,
Quack.com, USA

Voice offers the ultimate in wireless access, providing information on existing data pathways and using existing technology but in a new way. Several companies have recently begun offering platforms, tools, and processes for developing and delivering voice-based information applications as part of a SpeechWeb. These companies have been riding on the heels of a revolution in speaker-independent speech recognition that is fueled largely by consistent gains in processor power and memory availability as well as fundamental algorithmic improvements. This talk describes the enabling technologies behind the Quack/AOL Voice Services Platform (VSP), which is comprised of novel approaches to delivering information, to creating applications, and to publishing processes. The VSP not only duplicates the well-known models offered by web servers and feature-rich browsers in the web space, but extends this model to enable new kinds of application publishing paradigms that rely upon semantic models of information navigation rather than visual presentation models.

Jini™ Network Technology: Devices, Desires, and Designs

Session chair:
Gail Kaiser,
Columbia University, USA

Aleta Ricciardi,
Valaran Corporation, USA

This talk will examine the way in which Jini™ Network Technology facilitates both software development for distributed applications, and software integration. The connection between device integration and large, heterogeneous software systems will be examined. The technology itself will be presented and compared with other middleware, both distributed object and message-oriented, in the context of designing coherent, complex, scalable systems. I’ll close with a use case showing that the technology enables rapid, clean software practices, and how these in turn lead to a simplified, yet more powerful, notion of "work flow".

Simple Object Access Protocol (SOAP) and Web Services

Session chair:
Ric Holt,
University of Waterloo, Canada

Arthur Ryman,
IBM Canada Ltd., Canada

Simple Object Access Protocol (SOAP) is an exciting new technology for developing Web Services. A Web Service is a set of related application functions that can be programmatically invoked over the Internet. In contrast to traditional Web applications, Web Services are application building blocks that use Extensible Markup Language (XML) for information interchange. In this session you will learn about SOAP, Web Services, and related standards including Web Services Description Language (WSDL) and Universal Description, Discovery and Integration (UDDI). These technologies will be demonstrated using the IBM XML and Web Services Development Environment which is available for free download from the alphaWorks Web site at http://www.ibm.com/alphaWorks/tech/WSDE.

Auditing Legacy Systems for Security and Survivability

Session chair:
Prem Devanbu,
University of California, Davis, USA

Tom Longstaff,
Carnegie Mellon Software Engineering Institute, USA

In our rapidly changing IT environment, it is essential that the security posture of all systems and networks are understood. This is extremely difficult when most of the systems that make up our infrastructures are legacy systems. Current state of the art techniques for auditing systems assume that expertise exists in all of the systems and platforms that make up the environment, when in fact many systems that are essential in the infrastructure predate any member of the auditing team. In this case, we show how use cases and intruder scenarios can be used to determine which systems are important from a security perspective and which services and properties of these systems must be verified. These techniques are part of the Survivable Network Analysis method, developed at the Software Engineering Institute to provide a measure of survivability for complex system architectures.

AntiPatterns in Software Architecture

Session chair:
Margaret-Anne Storey,
University of Victoria, Canada

Tom Mobray,
World Wide Institute of Software Architects (WWISA), USA

This presentation will provide an introduction to common AntiPatterns in Software Architecture, and their resolution through reference models. AntiPatterns are an intriguing variation of design patterns. AntiPatterns clarify ineffective software practices, as well as raise awareness of alternative solutions. In the context of software architecture, AntiPatterns can clarify the necessity of problem-solving skills revealed in software engineering reference models, such as, the Software Design Level Model (SDLM) and the Reference Model for Open Distributed Processing (RM-ODP). In particular, this presentation will discuss how traditional software engineering assumptions become serious AntiPatterns, when applied to distributed software architectures.

Dependability of Embedded Systems

Session chair:
Anatol W. Kark,
National Research Council, Canada

John Knight,
University of Virginia, USA

Embedded systems present especially difficult challenges in software engineering because they usually operate in real time on machines with modest resources and can cause extensive damage if they fail. In practice the interplay between systems and software plays a significant role in dependability and must be considered in embedded software development. In this presentation the basic issues of dependability as they apply to embedded systems will be discussed, and several systems-engineering and software-engineering techniques for improving dependability will be reviewed. Topics to be covered include hazard analysis, fault-tree analysis, formal specification, design for safety, and verification.

Friday, May 18, 2001; 1:10 p.m.–1:50 p.m.

Inter-Language Object Sharing with the Common Language Runtime: Infrastructure for MS .NET

Session chair:
Hausi A. Müller,
University of Victoria, Canada

Jennifer Hamilton,
Microsoft Corporation, USA

The Common Language Runtime (CLR) is language and platform-neutral, and provides the underlying infrastructure for the Microsoft .NET Framework. It consists of several components, including a garbage collector, class loader, metadata engine, just-in-time compiler, and debugging and security services. This talk will introduce the CLR, describe its design, and demonstrate how it enables inter-language object sharing.

Friday, May 18, 2001; 1:10 p.m.–1:50 p.m.

Collaborative Software Engineering

Session chair:
Paul Sorenson,
University of Alberta, Canada

Alan Brown,
Catapulse, Inc., USA

Software development is a collaborative activity involving the sharing of ideas, artifacts, and knowledge among teams of engineers. Many elements are emerging to enhance the importance of collaboration in software development geographically dispersed teams, more partnering within and across organizations, and leveraging of the Internet as a coordination infrastructure. In particular, the future of software development will be through leveraging the Internet as the base on which collaborative development services will be offered. To be successful requires that the next generation of software development environments be based on the "Three C’s"-community, collaboration, and coordination. This presentation examines the requirements for future software development environments, illustrates the kinds of services that must be offered, and examines the challenges that must be overcome in collaborative environments for building the next generation of enterprise scale software solutions. As a result, the presentation explores the current state of collaborative software engineering, analyses the currently available collaborative technologies, and establishes the current state-of-the-practice in collaborative software engineering.
