Leigh Dodds introduces the Friend-of-a-Friend vocabulary.
2/5/2004
|
The FOAF ("Friend of a Friend") project is a community driven effort to define an RDF vocabulary for expressing metadata about people, and their interests, relationships and activities. Founded by Dan Brickley and Libby Miller, FOAF is an open community-lead initiative which is tackling head-on the wider Semantic Web goal of creating a machine processable web of data. Achieving this goal quickly requires a network-effect that will rapidly yield a mass of data. Network effects mean people. It seems a fairly safe bet that any early Semantic Web successes are going to be riding on the back of people-centric applications. Indeed, arguably everything interesting that we might want to describe on the Semantic Web was created by or involves people in some form or another. And FOAF is all about people.

Bob DuCharme finds that XSLT 1.0, even after four years, is still solving problems as more data becomes available in XML.
2/5/2004
|
This month I'm taking a break from covering XSLT 2.0 to describe how the combination of XSLT 1.0 and an application with an open XML format solved a problem for me. I solved this problem so quickly and easily that it got me thinking about how the combination of XSLT 1.0 and the increasing amount of open XML formats are opening up a world of simple, valuable new applications and utilities for us to write.

Validating XML Documents Against XML Schema: Learn the three methods involved: SAX parser, DOM parser, and XSD validator
2/5/2004
|
XML documents are increasingly being used as a format of data exchange. But for an XML document to be acceptable to different developers/users, the XML document should conform to a standard structure. XML Schema is an XML-based representation of the structure of an XML document. Through its support for datatypes and namespaces, XML Schema has the potential to provide the standard structure for XML elements and attributes. However, to check if an XML document conforms to an XML Schema, the document must be validated against that XML Schema. This tutorial explains the procedure for performing that validation using parsers for the Simple API for XML (SAX) and Document Object Model (DOM), as well as an XML Schema Design (XSD) validator. Table 1 compares the different purposes of each of these components. In each case, we will use the Oracle XML Developer's Kit (XDK) 10g Beta to perform the validation.

Introduction to Web services and the WSDK V5.1
2/4/2004
|
Interoperability is one of the great promises made by the Web services architecture. This is the ability for different applications to work together, even though they are running on different operating systems, on different hardware architectures, and using different application infrastructures. In a continuation of the WSDK tutorial series, this tutorial demonstrates Web services interoperability, specifically between Microsoft .NET Web service clients and IBM WSDK Web services. The authors will use Microsoft Visual C# and the Microsoft .NET Framework SDK Version 1.1 to demonstrate the process of creating simple .NET Web service clients against earlier examples from this tutorial series.

XML 1.1, Namespaces in XML 1.1, XML InfoSet (2nd Ed.) and XML 1.0 (3rd Ed.) achieve W3C Recommendation status
2/4/2004
|
XML 1.1 names are designed so that everything that is not forbidden (for a specific reason) is permitted. XML 1.1 adds NEL (#x85) to the list of line-end characters. For completeness, the Unicode line separator character, #x2028, is also supported. XML 1.1 allows the use of character references to the control characters #x1 through #x1F, most of which are forbidden in XML 1.0. XML 1.1 defines a set of constraints called "full normalization" on XML documents, which document creators SHOULD adhere to, and document processors SHOULD verify. Using fully normalized documents ensures that identity comparisons of names, attribute values, and character content can be made correctly by simple binary comparison of Unicode strings. The distinction between XML 1.0 and XML 1.1 documents is indicated by the version number information in the XML declaration at the start of each document.
Changes in Namespaces in XML 1.1 spec include: a mechanism is provided for undeclaring prefixes; and namespace names are Internationalized Resource Identifiers (IRIs), rather than URIs.
This third edition is not a new version of XML. As a convenience to readers, it incorporates the changes dictated by the accumulated errata to the Second Edition of XML 1.0, dated 6 October 2000. In addition, markup has been introduced on a significant portion of the prescriptions of the specification, clarifying when prescriptive keywords such as MUST, SHOULD and MAY are used in the formal sense defined in IETF RFC 2119.

New Specification Ties Web Services to Events
2/2/2004
|
BEA Systems Inc., Microsoft Corp. and TIBCO Software Inc. have teamed up on a software specification for Web services that publish and subscribe to one another. With this specification, WS-Eventing, organizations could build Web services for shipment-tracking and credit-card processing programs that are triggered by real-time business events, such as when an item ships from a warehouse. Some other events are a phone ringing, an order being placed, a package shipping, a printer running out of paper, a favorite team scoring or a stock hitting a price point.

Autonomous Services and the New Information Architecture
1/31/2004
|
Services are the new paradigm for designing integrated and distributed software systems across local and wide area networks. It is gradually becoming a pragmatic alternative to the now classic "N-Tier Architecture" as the guiding model for most commercial distributed systems. Services are an evolution of the existing conceptual principles behind distributed components, but contain some novel changes in emphasis. XML Web Services are actually a specific case of the larger trend of leveraging extensible metadata as a means to make software more flexible and re-usable, as .NET has accomplished with Intermediate Language and the Common Language Runtime. There are many different definitions of "services" and "services oriented architecture" out there, making all of these terms rather confusing. For the purposes of this article, the following describes what I define as a service: Services are network-accessible software components that encapsulate access to a set of data. They can easily interoperate with any computing architecture or programming model. They are only accessed through self-describing and extensible messages, usually XML-based. Standard schemas and protocols are defined in this universal message format to invoke, query, compose, or configure these services dynamically.

Use language-specific tools for XML processing: Alternatives to SAX and DOM
1/30/2004
|
DOM and SAX are the two best known systems for XML processing, but they are really compromises across programming languages. As such, they do not take advantage of any language's particular strengths. Often it is better to duck conventional wisdom and use special APIs that take advantage of particular strengths.

Designing and Managing an XML Warehouse
1/30/2004
|
Data present on the Web is unstructured, or has incomplete, irregular, or frequently changed structure. XML is becoming the universal data exchange model on the Web. It has been shown that XML is well suited for representing semi-structured data. Compared to HTML, XML provides explicit data structuring, and data presentation is separated from data content. The aim of this chapter is to present a method for designing and managing an XML warehouse. We have designed and implemented a browser to graphically define XML views in order to simplify and improve the specification of XML views. Furthermore, we also have proposed a strategy for storing XML data in a relational DBMS.
