XML 1.0 Superset Makes XML Concise
1/18/2004
|
Because XML was not designed for data, it has serious ambiguities and constraints. These limitations are hard for many to understand because most articles never address them. ConciseXML, a superset of XML 1.0, aims to solve not only these limitations but also the verbosity of XML.

XML-RPC in Java programming: The simplest route to interapplication communication
1/17/2004
|
Interapplication communication can be a nasty problem for programmers. Many of the available options, such as JNI, can be difficult to use. XML-RPC provides a much easier solution. It's clean, simple to implement, and well supported by open source libraries for most popular programming languages (such as Java language and C++). If you have a Java application, for example, that needs to talk to an application written in C++, XML-RPC just might be the simplest approach. In this article, software developer and coach Roy Miller talks about what XML-RPC is and how to use it effectively.

Use XML directly over HTTP for Web services (where appropriate)
1/17/2004
|
SOAP technologies usually exchange XML over HTTP, but SOAP has its pros and cons, and a lot discussion has focused on how to use XML more directly to communicate between applications. This tip describes the direct approach, and discusses where it is most appropriate. It also discusses how to use WSDL to describe such services.

Web Services project roles: The team perspective
1/17/2004
|
This article describes the many different job roles involved in Web services development projects, what their goals are, what their tasks are and how they work with each other. It does not go into detail over the actual tasks to be performed (such as creating a doc/literal service from WSDL); rather it tries to give IT staff of any background overall guidance on what they should be thinking about when approaching a Web services project. The intention is that this article can help an IT department figure out how to organize its projects better and plan for the full picture.

Developing a Web service on Linux: Using IBM's WebSphere Studio products
1/17/2004
|
This article walks you through building and testing a Web service on Linux, using a hypothetical banking application as an example. We'll use the Web service tools and Extensible Markup Language (XML) editor in WebSphere® Studio Application Developer 5.0 from IBM® to develop the Web service for the server. Then, we'll create a client application to access the service. Finally, we'll test the service and client application in WebSphere Studio's test environment. Along the way, some Linux idiosyncrasies are highlighted for the newbie.

Web Services: ATL Server Versus ASP.NET
1/17/2004
|
In the November 2003 issue of MSDN® Magazine I looked at the basic architectural differences between ATL Server and ASP.NET to explore two modern approaches to developing Web sites using Microsoft technologies. I looked primarily at developing a forms-based user interface with each framework. ASP.NET centers around the ASP.NET pipeline and some classes running in the common language runtime (CLR). ATL Server uses custom ISAPI extension DLLs and server response files (SRFs). This month I'm going to compare building Web services using ATL Server versus building them with ASP.NET.

New Version Showcases Native XML Type and Advanced Data Handling
1/17/2004
|
The next version of Microsoft SQL Server, code-named "Yukon," represents quite a few steps forward in the evolution of XML integration. Yukon supports native storage of XML data using the XML data type, which makes it possible to run native queries on XML data using the emerging industry standard XQuery language. Data integrity of the XML data type can be enforced through schema validation and XML-based check constraints, and special indexes can be defined that help speed up queries. In addition, Yukon has the built-in ability to expose its data through Web services. This article discusses these and other XML features of Yukon.

XML Report from the Microsoft PDC 2003
1/17/2004
|
This issue marks three years of The XML Files. As I reminisce over my personal XML journey and how simply it all began, I'm astonished at how firmly rooted XML is in today's software development landscape. I always said "XML will change the world," but only after reflection did I realize that it has actually happened. XML was everywhere at the November 2003 PDC. There weren't many sessions that didn't at least mention XML or some other new "X" technology. Although Microsoft has always been a leader in XML, their innovative use of XML in future technologies highlights their commitment to interoperability. In this installment of The XML Files, I'll summarize the juicy XML activity at the PDC. You can find the PDC session slides at http://msdn.microsoft.com/events/pdc/agendaandsessions/sessions. Please note that much of the information in this month's column covers beta releases and, as such, is subject to change at any time.

Recordare LLC, an Internet music software and publishing company, has released version 1.0 of MusicXML. MusicXML is the first file format that allows the common Western music notation used in printed sheet music to be fully shared among a wide range of computer applications. Recordare has also released new versions of its Dolet for Finale and Dolet for Sibelius plug-ins that support MusicXML 1.0. The Dolet plug-ins serve as "universal translators" between music notation programs. Dolet for Finale 1.3 reads and writes MusicXML files, allowing Finale to communicate with any other application that supports MusicXML. Dolet for Sibelius 1.1 writes MusicXML files that can be shared with users of Finale, Turandot, and other programs that can read MusicXML.

Character Repertoire Validation for XML
1/14/2004
|
In this article I present a small schema language for XML -- which can be used to restrict the use of character repertoires in XML documents -- called a Character Repertoire Validation for XML (CRVX). CRVX restrictions can be based on structural components of an XML document, contexts, or a combination of both.

Uche Ogbuji explains how to use SAX to build specialized Python dictionaries.
1/14/2004
|
People have always liked to complain that Python is slow. People have always liked to complain that XML processing is slow. I've always thought both complaints are typically misguided. Neither Python nor XML emerged out of the need for ultrasonic speed at runtime. Python emerged as an expressive language for programming applications, and XML as an expressive system for building data representation into applications. In both cases the goal for the resulting applications is ease of maintenance. This ease primarily comes from the expressiveness that Python and XML allow. One should expect that such gain in productivity would be matched by a corresponding loss in some area, and sometimes the deficit comes from performance. Complaints about the downsides of this tradeoff often stem from premature optimization, when developers insist on basing key decisions on meaningless benchmarks rather than considering the entire profile under which an application operates.
