COURSE TEXTBOOK

• Harold, E. R. & Means, W. S. XML in a Nutshell (2nd Edition). O'Reilly, 2002.

1 - January 21: Introduction to Laboratory in Document Engineering

2 - January 28: XML DTDs {and,or,vs} W3C XML Schema

• W3C. XML Schema Part 0: Primer (W3C Recommendation, 2 May 2001) [sections 1 & 2 through 2.3.1]. http://www.w3.org/TR/xmlschema-0/
• W3C. XML Schema Part 2: Datatypes (W3C Recommendation 02 May 2001). [sections 1.1, 1.2, table at beginning of section 3]. http://www.w3.org/TR/2001/REC-xmlschema-2-20010502/
• Harold & Means. XML in a Nutshell (2nd Edition). Start learning to use Chapter 21, Schemas Reference

3 - February 4: Exploiting XPath in XML Transformations

4 - February 11: Schematron

• Leigh Dodds. Schematron: validating XML using XSLT. April 2001.http://ldodds.com/papers/schematron_xsltuk.html
• Kip Hampton. Web Content Validation with XML::Schematron. January 23, 2002.http://www.xml.com/pub/a/2002/01/23/perl-schematron.html.
  You only need to read the first section (web page) of this article (sections 'Introduction' and 'Writing Schematron Schemas').

5 - February 18: XML Pipelines

• Erik Bruchez. Building Applications With Reusable XML Components. (www.flashline.com)     LOCAL COPY
• Erik Bruchez. An Introduction to XML Pipelines. Version 1.2. Orbeon, Inc. LOCAL COPY    This paper goes a bit beyond the previous reading and should give you a greater sense of the capabilities of XML pipelines/flows. The examples use "XML Pipeline Definition Language" which is just one of the pipeline languages available. Don't worry about trying to understand the language -- the important thing is for you to get an understanding of the capabilities of a pipeline definition language and supporting software components/framework. Sections 3.5 and its subsections are optional; although, you should understand that good pipeline technology should support Figure 7.

6 - February 25: Simple SOAP and Web Service Clients

• Yader & Webber. The Battle to Transport XML Business Documents. IDEAlliance XML 2002 Conference, December 2002. http://www.idealliance.org/papers/xml02/dx_xml02/papers/05-02-04/05-02-04.html
• Harold & Means. XML in a Nutshell (2nd Edition). Chapter 15 (243-245),

7 - March 4: XML and User Interfaces

• Erik Burchez and Omar Tazi. Integrating JSP/JSF and XML/XSLT: The Best of Both Worlds. http://www.theserverside.com/resources/articles/BestBothWorlds/article.html This article provides a good historical overview, with examples, of Java and XML technologies used to create web applications. The first code snippet -- a Java servlet -- is a good reminder of how far the technology has come.

8 - March 11: User Interfaces + Schematron + SOAP + Pipelines

9 - March 18: Formal Modeling Techniques and UML

• Scott. "UML Basics." http://www.iconixsw.com/UMLzone.html (Powerpoint presentation) (key concepts are: class diagrams, relationships, adornment, packages, behavioral diagrams, interaction diagrams, activity diagrams) LOCAL COPY (download this zip file)

10 - April 1: RosettaNet Business Process Patterns

11 - April 8: XML Programming Models

• Harold & Means. XML in a Nutshell (2nd Edition).Chapter 17, Programming Models,
• Harold & Means. XML in a Nutshell (2nd Edition).Chapter 18, Document Object Model (DOM). (When you read this, you want to get a sense of the various interfaces/methods provide by DOM. For example, understand how to create and set an attribute on an element. It may be helpful to look at the specific examples in Chapter 24, DOM Reference.)
• Niel Bornstein. XML Data-Binding: Comparing Castor to .NET http://www.xml.com/pub/a/2002/07/24/databinding.html?page=1

12 - April 15: UBL and BABL Document Model Patterns

13 - April 22: Building a Web Service

• Dion Alaer. Creating Web Services with Apache Axis, 5/22/02, OnJava.com. This article introduces a couple of different ways to writing web service services and clients using Apache Axis (a SOAP based application server). If you want to see architectural diagrams, see the recommended reading.

Recommended Readings:

• Bob Glushko The Web Services Vision, IS 290-4, 26 February 2003 Review slides 15 through 32.
• Brian Hayes. XML Messaging Review the SOAP concepts in lab lecture 6, February 25. Much of this is covered in Bob Glushko's lecture, above.
• WebServices.org. Introduction to Axis, LOCAL VERSION FOR PRINTING This article provides a reasonable introduction to the features of a web service platform. This article is based on Axis alpha release 3 and the latest version is Axis 1.1 Release Candidate 2. As such, the architectural presentation is not entirely accurate. Remember to read this article for concepts.

14 - Apr 29: Architectures for Enterprise XML Applications

• Gough & Mitchell. A Web-Services API for a Government Procurement Application. IDEAlliance XML 2002 Conference, December 2002. http://www.idealliance.org/papers/xml02/dx_xml02/papers/04-02-03\04-02-03.html
  This will serve as the basis for the class discussion. An excellent paper.
• Patterns Tutorialhttp://www-106.ibm.com/developerworks/patterns/multimedia/version4/Flash_web.swf (requires Flash)
  Quick introduction to the the IBM e-business patterns. "Read" the first three sections of the tutorial.
• IBM. Patterns for E-business. http://www.ibm.com/developerworks/patterns/
  You'll need to drill down on the various pages. This is a library of document patterns that can be reused (perhaps the equivalent of BABL and UBL for architecture). As you familiarize your self with the library, do so in context of the calendar/event system example that we have been using for the assignments.

15 - May 6: XML and Databases

• Bourret, Ronald. XML and Databases. http://www.rpbourret.com/xml/XMLAndDatabases.htm Approx. 21 pages. Ronald Bourret also has a excellent list of XML and database resources at http://www.rpbourret.com/xml/

16 - May 13: Course Wrap-Up

• Pollock, Jeffrey. The Web Services Scandal. August 13, 2002. EAI Journal. http://www.eaijournal.com/PDF/AugustCoverStory.pdf
  "Just because you know the standards - WSDL, XML, SOAP, and UDDI - don't think you're all set for comprehensive integration. The issue of data semantics has been overlooked by most in the media. Enterprises do so at the risk of failed integration projects."
  
  When the web-services hype is getting to be too much for you or your employer; this is a good sobering article. Hopefully, you've learned enough in 290-4 and 290-8 to appreciate the issues presented here.
  4 pages.
