XML Core Technology: Inside XML Schemas XML Schemas provide a means of defining the structure of XML documents as well as rules and constraints related to the elements of that structure. This paper provides an insight into the mechanics of XML Schemas, as well as a look at the XML-based code syntax. [view] XML Core Technology: SOAP in a Nutshell The Simple Object Access Protocol is becoming a prominent communications alternative to existing binary protocols. Here we delve into the technology behind this XML protocol, and learn a bit about the structure of SOAP messages and envelopes. [view] XML Core Technology: Transforming Data with XSLT XSLT allows for an efficient and immediate conversion of XML documents into a number of different output formats. XSLT's relationship to the XSL language is discussed in this paper, as well as a step-by-step introduction to the creation of an XSLT template. [view] XML Core Technology: Understanding DTDs The predecessor to XML Schemas, Document Type Definitions are still widely used, and are considered a milestone in the evolution of the XML language. DTD concepts are explored here, supplemented by code samples. [view] XML Core Technology: What You Should Know about XPath Designed specifically as a supplementary technology for XSLT and XPointer, the XPath language provides a comprehensive addressing syntax for accessing XML data. The focus of this paper is on XPath's relationship with XSLT. [view] XML Core Technology: Why SAX is Good for DOM When accessing and processing larger XML documents, the Simple API for XML offers an attractive alternative interface to the Document Object Model (DOM). A comparison between DOM and SAX is provided in this paper, as well as recommendations regarding the use of one API over the other. [view] XML Core Technology: An XHTML Primer Using a series of code samples, this paper takes a detailed look at the differences between XHTML and previous versions of HTML. The overall goals and some future applications of this new XML-compliant upgrade to HTML are also provided. [view] XML Core Technology: XLink - Inside and Out XLink provides a means of embedding intelligence into hyperlinks used by XML documents. This paper provides an overview of this powerful linking language, as well as a look at the code syntax behind XLink structures. [view] XML Core Technology: Data Access with XQuery A query language designed specifically for XML data, the XQuery specification establishes a new data access paradigm. This paper provides an overview of the XQuery language, while contrasting XQuery statements to their SQL counterparts. [view] XML Core Technology: XSL versus CSS The Extensible Stylesheet Langauge supplies all of the functionality already provided by the Cascading Stylesheet Language, however choosing XSL over CSS may not always be the right decision. This paper provides a thorough comarison of the two technologies. [view] XML Core Technology: Another Introduction to XML A gentle introduction to concepts and syntax, for those new to the world of XML, this article also provides some historical background and explains how XML is positioned within maintream IT architecture. [view] XML Data Strategy: Unifying Corporate Data & Documents By standardizing on XML as both a corporate document and data format, global searches across repositories and document-sets can be performed using XQuery. This paper discusses the concepts behind achieving such a unified view of corporate information. [view] XML Data Strategy: Replacing HTML Documents with XML This paper explores how the presentation and navigation features provided by HTML and XHTML are being enhanced through supplementary XML technologies. How this new XML platform may one day replace HTML altogether is also discussed. [view] XML Data Strategy: Meta-Enable Your Enterprise Infusing your corporate documents with metadata by converting them to XML can establish an entirely new platform for content management and document sharing. This paper takes a look at the issues involved with achieving this new environment. [view] XML Data Strategy: The XML Data Custodian Whether you use XML for content management, or as a universal data transfer format, there will come a time when you will need to begin authoring and standardizing XML Schemas. A recommended position for the administration of XML standards and business rules, the role and responsibilities of the XML Data Custodian are defined in this short paper. [view] XML Best Practices: Integrating XML into the Enterprise Many organizations underestimate the impact of introducing XML into an established IT environment. This paper provides ten high-level best practices for minimizing this impact and maximizing the benefit of XML in your organization. [view] XML Architecture: The Wireless Enterprise Wireless application devices have built-in mini or micro-browsers capable of accessing Web content over the Internet. This paper provides an overview of wireless technology, with a focus on the WAP framework. [view]		Whether you are building a service-oriented solution or just working with Web services, there is one thing you'll notice very quickly: you cannot make a move without involving XML. The core family of XML standards can be positioned to establish a harmonized data representation layer that blankets existing disparity in support of enterprise-wide data federation. The short articles published here provide concise overviews of the key open technologies that support and extend XML functionality, and also explore issues around how XML can be leveraged throughout the enterprise.
