As published the W3C XML Schema specification references XML 1.0 explicitly, and incorporates by reference certain key definitions, in particular those of the 'Char', 'Name' and 'S' character classes. XML 1.1 changes the contents of these classes, so although nothing in the existing XML Schema specification specifically bars infosets produced by XML 1.1 conformant parsers, such infosets, if they exploit any of the relevant changes in XML 1.1, will not be accepted as valid by conformant XML Schema 1.0 processors.
XSLT stylesheets are designed to transform XML documents. Coupled with Java extensions, stylesheets can also be a powerful complement to XML Schema when grammar-based validation cannot cover all the constraints required. In this article, Peter Heneback presents the case for validating documents using XSLT with Java extensions and provides practical guidance and code samples.
The rules for finding schema components when validating a document using W3C's XML Schema 1.0 are widely misunderstood. This presentation will the rules for constructing a schema and describe the reasoning behind the design.
Designers of XML formats have to face the problem of how to design their formats to be extensible and yet be resilient to changes due revisions of the format. This presentation covers various techniques and considerations for versioning XML formats.
In technical writing, synonyms and variants should be used judiciously and often avoided altogether. The use of one term consistently to express a given concept is preferred so that communication is clear and so that translation costs are minimized. For this reason, when synonyms and variants do exist in popular usage, it is common practice in commercial environments to choose one of the terms as the “preferred term.” This indicator of preferred usage needs to be documented in glossaries. Due to the limitations of markup languages for creating glossaries, usually the so-called preferred term is identified simply by making it the headword in a glossary entry and providing a definition in this glossary entry.
Document Model selection is a key success factor in XML. Approaches include: adopting an existing model, modifying a model to meet your needs, and creating one to meet your needs. Advantages and disadvantages of each are discussed.
Our work presents an experiment with a modeling tool that captures domain knowledge in a fashion natural to business users while producing formal models for use in IT processes. We demonstrate the use of this tool for designing XML Schemas.
An image, a caption and the image credit. That can't be hard to get the associations right, can it? Delve into the discussion about markup, semantics and microformats of a seemingly simple issue.
There has been a lot of attention to the legal encumbrances in Microsoft's new MS XML format. In this article we'll look at the technical side, and try to show you how the design of these formats affect interoperability. After all, that is the purpose of open standards.
The next century will be an XML century, make no mistake about it. All our documents, even checks, credit card slips, personal letters, recipes, technical documents, everything, will benefit from XML technologies. Students are already learning XML in schools, and big businesses are using it to publish their databases on the web. The appearance of the electronic spreadsheet ten years ago changed the way we do business. XML will change the way we write documents.
The UK Local e-Government Standards Body was established late in 2003, and tasked with compiling an XML based data standards catalogue for use by UK Local Authorities. This is to be achieved by mapping existing standards, identifying gaps to be filled, advising and supporting local Councils, their partners and suppliers on the interpretation and adoption of standards, and establishing processes for developing new standards as required. However, UK Local Authorities have been developing e-services for several years already, so this new effort has to take place in a context where many projects are already under way, using a variety of business models, and with diverse approaches to XML interoperability design. An additional factor is the traditional tension between central and local government, which has led to patchy and inconsistent adoption of the national UK e-Government Interoperability framework. This paper is an account of the methodology developed by CSW Group Ltd and the LeGSB to tackle this situation.
DITA is not another tool like FrameMaker or MS Word. It is a standard and a specification that is supported more or less effectively by open-source and commercial tools. As a standard, DITA is a way of working, a way of thinking about the structure of information. It's greatest benefits come from understanding the architecture and deciding if you're ready to make the leap into a new authoring and publishing environment. It's definitely worth the effort because the benefits to productivity and quality are huge.
Standard Generalized Markup Language (SGML) is an accepted standard today. It promises to free many companies and industries from problems with document conversion, compatibility, and interoperability. Whether you’re curious about SGML’s benefits or actively planning to implement SGML, this workshop can help. As a participant, you will learn how to apply a life-cycle approach to implementing SGML. Through hands-on exercises, you will gain the knowledge to successfully plan and implement SGML solutions.
Information Mapping is a proprietary method for the analysis, organisation, and presentation of information. It is based on the needs of the users and their purpose in using the documentation. Information Mapping has three parts: analysis, organisation, presentation.
From initial data modeling, to technical XML Schema design and critical programmatic realization, we have an actionable, real-world set of comprehensive recommendations that can help you formulate a successful XML implementation.
Groovy Builders let you mimic markup languages like XML, HTML, Ant tasks, and even GUIs with frameworks like Swing.They're especially useful for rapid prototyping and, as Practically Groovy columnist Andrew Glover shows you this month, they're a handy alternative to data binding frameworks when you need consumable markup in a snap!
Microformats are markup that allow expression of semantics in an HTML document. Microformats are designed for humans first and machines second, and are a set of simple, open data formats built upon existing and widely adopted web standards.
The high integration costs which exist today mean that we must automate interface maintenance and integration tasks or go insane, or worse, out of business. Ongoing pressure to reduce software development costs while increasing the quality and completeness of the work provide an opportunity for the use of model driven computing. MDA (Model Driven Architecture) is a technique for model based platform independent software specification based on the MOF (Meta-Object Facility) and XMI (XML Meta-data Interchange) standards from the OMG (Object Management Group). There are a number of tool vendors using XMI (especially UML (Unified Modeling Language) drawing tools) but common use and value seem to be slow to show themselves.
During the past twenty years, a huge number of custom languages - at least hundreds, perhaps a couple of thousand - have been attempted. Almost all have been miserable failures. That is to say, the vast majority have failed to achieve wide adoption, and those that were adopted have often failed to achieve their goals, whether of reducing costs, enriching applications, or both.
RELAX NG is a simple schema language for XML, based on RELAX and TREX. A RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema thus identifies a class of XML documents consisting of those documents that match the pattern. A RELAX NG schema is itself an XML document.
SGML (Standard Generalized Markup Language) is an international standard publishing technology that's increasingly being used in government, industry, and academia. Despite this growth, SGML is perhaps the most misunderstood technology around.
Web Services Description Language is the standard format for describing a web service in XML format. In this tutorial you will learn what is WSDL and Why and How to use it. WSDL is very easy to learn and very important for Web Services.
Almost every example of good dropdown navigation on the web today relies on a single, simple HTML structure: the nested unordered list. Without this structure, dropdown menus would be much more complex to build than they already are.
