X pointer would benefit from offering the option of developed modest feature set, many vendors involved in developing X pointer. Though many tried nobody has set the goal of speed implementation the single complete implementation of x pointer took about two weeks and four known external implementations of FIXptr proposal each took about half a day  compared to the process of x pointer implementations getting four implementations to  try the proposal on a casual basis was so easy and with this no users of x pointer would lose anything, many

Before XML Encryption and even after that a support has been added for asymmetric and symmetric keys in the WSS4J API. Below are few listings tat will show the XML encryption process by showing a sample input. Listing 1 will perform the encryption process for the demonstration of the working of WSS4J API. In order to perform this demonstration listings 2, 3, 4 will show the result of encryption method. All of these listings have slight differences and different formats. Contents of the listing 1 is replaced by listing 2 since it contains

W3C Working Draft 16 July 2007: Abstract This document is the specification of the Efficient XML Interchange (EXI) format. EXI is a very compact representation for the eXtensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources. The EXI format uses a hybrid approach drawn from the information and formal language theories, plus practical techniques verified by measurements, for entropy encoding XML information. Using a relatively simple algorithm, which is

ABSTRACT This paper is devoted to the construction of processors of a language for describing links between resources in XML documents, which is based on the application of functional programming methods and representation of XML data as S-expressions. An implementation in the high-level functional programming language Scheme, the system SXLink compatible with the XLink specification of the W3 consortium, is considered. A survey and comparative analysis of the existing implementations of the XLink language are given. Typical difficulties associated

The Extensible Markup Language (XML) describes a class of data objects called XML documents which are stored on computers, and partially describes the behavior of programs that process these objects. XML is a subset or restricted form of SGML, the Standard Generalized Markup Language (ISO 8879). The goal of XML is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML. XML customizes SGML in a

In this second installment, Bilal Siddiqui examines the usage model of XML Encryption with the help of a use case scenario. He presents a simple demo application, explaining how it uses the XML Encryption implementation. He then continues with his last implementation of XML Encryption and makes use of JCA/JCE classes to support cryptography. Finally, he briefly discusses the applications of XML Encryption in SOAP-based Web services. In Part 1 of this series, I gave an introduction to XML Encryption and its underlying syntax and processing. I examined

In the previous column of this series, we discussed the usage model of Web Services Security (WSS) and introduced WSS4J, a Java-based API for WSS, a project we will be constructing through this series. In this column, we start implementing the WSS4J API. The first section of this column discusses the role of different Java components in implementing the WSS4J API. One of the components is XML Security Suite for Java from IBM alphaWorks. The second section will provide a comprehensive tutorial demonstrating how to accomplish XML encryption using the

Introduction: This package contains an implementation of the W3C XML Schema Language, a recommendation of the Worldwide Web Consortium available in three parts: XML Schema: Primer and XML Schema: Structures and XML Schema: Datatypes. We consider this implementation to be complete except for the limitations cited below. The implementation has been extensively tested and known problem areas are set out below. In this document we also discuss our interpretation of the specifications where it seems to us particularly likely that others might arrive at a

W3C Schema can quickly become complex and difficult to determine if they are validating the correct vocabulary. The addition of embedded Schematron schema only makes this problem worse. Schema Unit Test (SUT) introduces a framework for testing XML Schema. This framework has two parts. The first is a namespace and vocabulary for embedding test cases into sample XML documents, designed to highlight what is legal and what is not legal in the vocabulary defined in the schema under test. This aspect is independent of what schema language is used and
