Applied XML Developers Conference 2003 West
applied topics for xml & web service zealots

July 10-11, 2003, Greater Portland, Oregon

Spirit of the Developer's Conference

The goal of the Applied XML Developer's Conference is to cut away all the unessential conference baggage and concentrate on why we're spending time at a conference in the first place -- the talks by industry experts and experienced practitioners. By doing so, we can keep the price, and your wasted time, to a minimum. In fact, if you don't go away with your head hurting from all the new ideas you've heard, we've haven't done our job!

BTW, just because I'm a Microsoft employee now, doesn't mean that I plan on taking away what's great about the Developer's Conference, including cross-industry and cross-platform coverage. The only thing that's different it's that I've found a sponsor willing to pick up of the cost (like my pay for the rest of the year : ). What that means is that I hope to keep costs at or below their traditional Developer's Conference levels while adding some things we've never had before, like wireless access during the sessions to drive your blogging readers mad w/ envy.

Session Abstracts

Day One Keynote
Dave Winer, Harvard Law School

[Don's Secret Topic]
Don Box, Microsoft

abstract pending

Sam Ruby, IBM

Explore the technical implementation and social ramifications of some of the currently popular techniques used to promote collaboration and group forming via weblogs.

Hard Core Messaging with WSE2
Keith Ballinger, Microsoft

Messaging -- SOAP doesn't discriminate, but developers do. SOAP promised to bridge the religious gap between tradional RPC style coding and document oriented messaging. With WSE v2, the Microsoft platform now supports both styles of SOAP messaging, rpc request/response and sync/async messaging. This talks will outline many different types of potential SOAP messaging and will provide and overview of the new messaging infrastructure in WSE v2. This provides developers with the necessary APIs to make design decisions about how the SOAP messages are processed on the send and receive sides.

Day Two Keynote: Why and How is Using Web Services to Provide Easy Access to the Platform
Jeff Barr,

Jeff will discuss how enabled a way for developers, merchants, and partners to provide customers with information retrieved from their databases in real-time using XML over HTTP and SOAP. He will discuss the development of the AWS platform and the next-generation features available via this platform. Find out how Web Services can meet with a customer base that is ready to explode into usage. Discover how to partner with parallel industries to cooperatively develop breakthrough technology at the pace that the market demands. Understand how the actualization of a progressive platform can spur systems innovation outside and within the company and be utilized in unexpected ways.

Point & Click XML Applications
Patrick Logan, Star Decisions

A handful of principles and patterns can place creativity mostly in our end-users' hands. XML and related protocols are the foundation, but knowledge about this foundation is not assumed about end-users. Prototype applications have been written in Python, but the ideas apply broadly and the components of a complete system could originate from many languages and tools. This presentation will consist of an explanation of the principles and patterns, and demonstrations of application construction and finished applications.

Validating Business Rules with XPath Assertions
Aaron Skonnard, DevelopMentor

Some XML applications don't require validation to function properly but others absolutely require it in one form or another to avoid disasters, whether it's through schema definitions or custom code. First we'll discuss when validation is a MUST, then we'll present different implementation techniques for tackling the problem. While doing so, we'll discuss the shortcomings of XSD especially when it comes to describing typical business rules that contain co-occurrence constraints. Then we'll present a declarative model for describing such rules through simple XPath assertions, which can be embedded in schema or WSDL definitions (a la Schematron). Throughout the session we'll walk you through a complete .NET sample that leverages the WebMethod framework to build a complete validation-oriented system.

When Sessions Meet SOAP: EJB 2.1 WebService Bindings
Ted Neward, DevelopMentor

The latest EJB specification contains bindings to allow EJB Beans to be accessed and invoked via W3C/WS-I standard web service bindings. In this talk, we'll examine whether this is a natural evolution of EJB, a last-gasp effort by Sun to remain relevant, or a revolutionary shift in the Java middleware platform.

SOAP, it wasn't Simple, we didn't Access Objects and its not really a Protocol
David Ing, Meridian Project Systems

Writing a business critical enterprise product from scratch using new programming languages, run-time and a new team just wasn't hard enough - so we added SOAP web services to the mix. This talk describes the XML adventures of the last two years using web services to bring a new product to market. Some of the real-world experiences discussed will contradict the current thinking of the use of WSDL, ASP.NET and XML Schema, so please be prepared for some awkward silences. It describes the design patterns that emerged from a service-orientated architecture and what lessons are still being learnt at every daily build. If you're contemplating starting your shiny new web services based product soon, then use this talk to save yourself some time, money and heartache. Warning: This talk contains explicit references to OO heresy - flaming torch / pitchfork not supplied.

Web Services in your Pocket
Brian Jepson, O'Reilly & Associates

Many phones that don't support rich client applications nonetheless support scaled down web browsing capabilities with a built-in WAP browser. Lack of rich client support doesn't mean that users of such phones can't participate in the Web Services Revolution, since XML can be easily turned into WML, the markup language used in WAP browsers. In this session, I'll show examples of repurposing content from RSS feeds and the Amazon web service; these techniques can be adapted for other XML sources to keep information in the palm of your users' hands.

Embedded Web Services. Feasible and Sensible?
Steve Loughran, Hewlett-Packard

This presentation looks at a embedded web service I worked on, part of a prototype for a CAD-related hardware product. After demonstrating the system and client applications, I'll talk about various design issues, discussing what worked and showing where Web Services, Axis, and my own code/design could be better. Alongside local use of an embedded SOAP service, comes long-haul usage: I'll cover the tricks and techniques that proved useful here, in the protocol, the implementation and the testing. To go embedded, we need discovery; I'll introduce the multicast XML based discovery protocol "WS-Discovery" I added to Axis and discuss the problems encountered, especially those with mobile users. We also need streamable SOAP messages with embedded attachments, and events/callbacks. I'll look at the issues and options here, but have no silver bullets. Although there are many compelling reasons to apply the Web Service architecture to embedded products, there are still valid arguments that the World Is Not Ready Yet, though there are special cases where it is viable. Yet it is the broad application of the concept that will lead to the greatest opportunities.

Rebuilding MSDN with Angle Brackets
Tim Ewald, Microsoft

MSDN is in the process of rebuilding it's core infrastructure, starting with a publishing plumbing built using XML. This talk takes a tour through our new XML pipeline, examining how we use schemas (it's not about types), XPath (what would we do without you), and XSLT (hello SQL statements) to implement logic declaratively. The talk concludes with a look at our next steps, including making our plumbing more generic and exposing XML content to users through RSS and Web services.

Design Web Services Visually With WSDL
Christopher Dix

If you throw enough specs together, XML gives us all the tools we need to view, edit, and code against a Web Service description. Using common household ingredients (XML, XSLT, SVG, WSDL), we can build graphical design tools to help developers work with Web Services. After that, we will pull these tools into the Visual Studio .NET environment to make Web Services development in .NET even easier.

A Steady and Pragmatic Approach to Dynamic XML Security
Rich Salz, DataPower

This is a detailed look at using XSLT, XPath, XPointer and emerging XML security standards to transform, parse and secure XML/SOAP for encryption, digital signatures and access control. Attendees learn the fundamental similarities and differences between XSLT, XPath and XPointer. Attendees come away with practical examples of implementing XML encryption and XML Digital Signatures for XML Web Service application development and deployment. Attendees also learn a basic understanding of XML encryption technology, digital signatures and XML security standards including 3DES, AES, SAML, XACL, XKMS and WS-Security.

Declarative UI using Scalable Vector Graphics
Don "XML" Demcsak

Have you ever wanted to create your own UI widgets, but didn't know the low level APIs for your platform's graphics engine? Or, what if you wanted to create your widget but needed to be cross platform, or even rendered in a browser. Well Scalable Vector Graphics can be your salvation. This session will show you how to create your own graphic mark up languages, and render them as SVG, thus eliminating the need to learn the low level graphics APIs. The examples will include interactive bar graphs, gauges, and a label generating web service that uses the SharpVectorGraphics SVG to GDI+ rendering engine.

XML on Large Power Transformers and Industrial Batteries
Patrick Cauldwell, Serveron Corporation

Since SOAP is inherently cross-platform in nature, it’s a perfect choice for communicating between disparate systems. However, if one of those systems happens to be running on a real-time operating system inside a dedicated hardware device, that poses some significant constraints on how SOAP can be used. Limited tools for dealing with SOAP, limited available memory, and a highly constrained programming model are all aspects of embedded systems that can influence how you structure the SOAP API for communicating with a hardware device. Furthermore, if the hardware device is to be deployed behind a corporate firewall without direct access to the internet, that also has to be taken into account when designing the API. Learn how a real company is solving exactly these issues in developing a distributed application for real-time monitoring of assets in the utility industry using SOAP-based XML Web Services.

Microsoft.Com Platform Content Services Preview (lunchtime demo)
Tarlochan Cheema, Microsoft Corp.

Much of the content that is available from is served up by MSCOM Platform Web services including Downloads metadata and urls, Catalog information, Multimedia, newsgroup postings via the Communities API, etc. Up to this point in time, this XML content has been available only internally.

The MSCOM Platform Team has created a project to provide access to XML content managed by various internal-use-only Platform Web services by means of a single Web service exposed to the Internet. The first release, which is a beta "Hello World" version, exposes Top 'n' Download information. In addition, working with several groups across and with the participation of interested groups across Microsoft, we've designed and built a reusable infrastructure for authenticating SOAP calls, throttling access to the service and gathering metrics around use of the service. This infrastructure will be used by all Internet-facing Web services from

Tarlochan Cheema will provide a brief description of the architecture and technology used, and will provide demos of the service itself and some sample applications built to consume the service.

PhotoScribe Suite – 2 XML Web Services and a Tablet PC (lunchtime demo)
Robert A. Wlodarczyk, a Microsoft Imagine Cup Winner

This application provides users the ability to organize and assign various types of meta-data with photos. Such data includes a description of the photo, which people are in a photo, Tablet PC ink, and copyright text. All of this is provided to end users via an XML Web Service that dynamically renders and rescales the photo to the user’s specified size. Photo album maintainers are given a Windows Forms based application to administer their albums, whereas visitors are given access to viewing and commenting on photos via a Web Application.
