XML (Extensible Markup Language) is a subset of SGML designed for delivery on the web. At present the standard is being developed under the auspices of the W3C Consortium. The activities are controlled through a wide variety of working groups within the W3C whose site includes details of current activities, discussion groups, links to developer mailing lists, status of recommendations, drafts and final recommendations (Note: the W3C issues"Recommendations" rather than "Standards".)

The range of information and resources related XML has expanded considerably, and continues to do so. In an attempt to keep our coverage brief we have published below edited news items and resources that have been generated through the El.pub Weekly news service. Due to the speed of developments in this area, resources featured on the page have the tendency to "age" fairly rapidly. Readers are therefore advised to consult more widely concerning the subject of XML.
The United Nations body for Trade Facilitation and Electronic Business (UN/CEFACT) and the Organization for the Advancement of Structured Information Standards (OASIS) have joined forces to initiate a worldwide project to standardize XML business specifications. UN/CEFACT and OASIS have established the Electronic Business XML Working Group to develop a technical framework that will enable XML to be utilized in a consistent manner for the exchange of all electronic business data.

The "Namespaces in XML" specification is a W3C Recommendation. Teaming up with XML, the specification allows authors to mix two or more XML-based languages in one document without conflict or ambiguity, thus promoting the modular development and reuse of XML languages and applications. The specification resolves potential name clashes by using the Web addressing infrastructure. Each element name in a document may be prefixed with a unique address, thus precisely qualifying the name. The specification paves the way for future developments in W3C's XML Schema Working Group, and data exchange based on the Resource Description Framework (RDF) architecture.
In recognition of the amount of confusion generated on the XML developers list concerning the XML Namespaces Recommendation, a document has been written which attempts to clarify the explanation in the official Recommendation.

The W3C XML Linking Working Group publish details of XLink which allows elements to be inserted into XML documents in order to create and describe links between resources. It uses XML syntax to create structures that can describe the simple unidirectional hyperlinks of today's HTML as well as more sophisticated links.
XBase, is a syntax for providing the equivalent of HTML BASE functionality generically in XML documents by defining an XML attribute named xml:base.

XML.com has published a number of articles on XLink, the W3C's XML Linking language for describing links between resources in XML:
- "What is XLink?" - provides an introduction to using the language.
- "XLink Reference" - examines the details of the specification, using examples to show the creation of extended and simple links between XML documents, including resources for XLink software and further reading.

This document presents requirements for the XPointer language. XPointer provides ways to directly identify any node, data, or selection in any XML document by describing its structure and context. An identified data location is called a "target". The XPointer specification is particularly meant to enable hyperlinks to identify any such data, regardless of whether there is (or even could be) an ID on the target or not. The XPointer specification is developed in the XML-Linking Working Group, building on Working Drafts developed in the XML Working Group.
The XBRL (eXtensible Business Reporting Language) Project Committee is a coalition of more than 30 US finance, accounting, software and government organisations, which is promoting the use of XML-based, XBRL, for the exchange of financial statements. It is hoped, by its supporters, that XBRL, (previously called XFRML), will provide the users of financial statements with a "new, free XML-based standard for preparing, formatting, distributing and analysing financial reports".

adXML.org is an international consortium of commercial companies which is aiming to define an advertising XML schema for both on-line and off-line media. The site includes details of the adXML formats being developed, and a resources page includes links to standards and XML-based activities in related sectors.
IBM, Lotus, Motorola, Nokia, Palm,, Psion and Starfish Software founded the SyncML Initiative to "develop and promote an open industry specification for universal data synchronization of remote data and personal information across multiple networks, platforms and devices". The founders of the initiative hope that SyncML will act as an XML-based data synchronisation protocol accross multiple applications including e-mail, calendar, contact management information, enterprise data stored in databases, web-based documents.
The SyncML Initiative is encouraging other companies to join to help in developing the specification, which the founders are hoping will find equal application in products ranging from web servers and laptops to PDAs and mobile phones.
The SyncML initiative has launched a number of documents designed to accelerate the development of this specification aimed at data synchronisation. A SyncML Architecture white paper has been published in the "Supporter Area" of the SyncML web site and contains a technical overview of the SyncML structural design. The white paper provides an insight into SyncML for supporting companies interested in developing SyncML-compliant client or server implementations.

There appears to be confusion amongst the XML development community concerning the relative merits of the Directory Services Markup Language (DSML) and Novell's DirXML proposal. Details of both proposals are available on the web. A number of vendors have established the Directory Interoperability Forum with the intention, to speed development and deployment of directory-enabled applications that run across different computing environments. The member companies will work closely with industry associations such as the Internet Engineering Task Force (IETF), The Open Group and the DMTF to speed enhancement and adoption of directory standards.

NewsML, being developed by The International Press Telecommunications Council (IPTC), is an XML-based standard to represent and manage news through its life-cycle, including production, interchange and consumer use. It is intended that this framework standard will build on the intellectual property invested in existing IPTC standards such as the Information Interchange Model (IIM), News Industry Text Format (NITF) and the IPTC's widely used Subject Classification Standard. Using Extensible Markup Language (XML), it is intended that NewsML will draw appropriately on existing and emerging W3C recommendations.
IPTC was established in 1965 to safeguard the telecommunications interests of the world's press. Since the late 1970's its activities have primarily focussed on developing and publishing industry standards for the interchange of news data. At present the IPTC membership is drawn mainly from the major news agencies around the globe but it also has a strong representation from newspaper publishers as well as system vendors. Membership of IPTC is open to organisations and companies concerned with news collection, distribution and publishing.

The News Industry Text Format (NITF) is an XML-based DTD designed for the markup and delivery of news content in a variety of ways, including print, wireless devices and the web. It was developed by the IPTC and the Newspaper Association of America.
NITF was first released in spring 1999, with a number of improvements being made since then. Both the NITF and, the related, NewsML (News Markup Language), wrapper can be stand alone but may also be used in a complimentary manner as NITF objects can be moved within and managed by NewsML in a multimedia environment.

Reuters - XML for news
The Reuters Internet Delivery System (IDS) enables Reuters to deliver its news content in Extensible Markup Language (XML). Text news as well as photos and video files can be delivered either as independent media streams or as linked multimedia news packages. Web publishers can choose to display the content using their own XML style sheets or they can use a display template supplied by Reuters. IDS will be used as the principal delivery mechanism for Reuters growing range of Online Report services. IDS utilises a Reuters prototype NewsML DTD (Document Type Definition).
The Open Applications Group (OAGI), a non-profit industry consortium, have published a number of Extensible Markup Language (XML) Document Type Definitions (DTDs) that "define interoperability APIs for Financials, Human Resources, Manufacturing, Logistics, and Supply Chain components". OAGI Members have built a common model for business software application component interoperability over the last three years. The model is described in their Open Applications Group Integration Specification (OAGIS) which has now been expressed in the form of XML DTDs. The DTDs will be free of charge to download and use, but a license agreement will be enacted to maintain ownership of intellectual property.
IBM has developed a specification for defining and implementing electronic contracts. Based on XML, The Trading Partner Agreement Markup Language (tpaML) enables companies to automate business-to-business (B2B) transactions, by defining how trading partners interact.

The W3C is developing an XForms Data Model, which is described as "the next generation of web forms which will separate purpose from presentation". The W3C HTML Working Group has a charter to develop a form architecture that provides a better match to workflow and database applications, to the proliferation of new Web-enabled devices, and to the XML-driven web. The XForms Subgroup has produced a forms architecture that separates data modeling, logic, and presentation. The XForms Data Model has emerged as the first in a series of XForms specifications.

A meeting held under the auspices of the International Institute for Communication and Development considered the potential of the Extensible Markup Language (XML) for improved information sharing in the international development community.
Potential applications of a Development Markup Language (DML), an XML Document Type Definition (DTD) specific to the international development sector, were demonstrated and discussed. Participants shared lessons learned from previous joint standards and information initiatives such as IDRIS, DDBS, INDIX, Dublin Core, CEFDA, and CALS. Plans for several pilot projects emerged from discussions. Notes from the meeting held in Ottawa, Canada, on January 13-14, 1999 are available online along with resources on DML and XML.
Web Interface Definition Language (WIDL)
In a bid to address the problem of direct access to Web data from within business applications, the Web Interface Definition Language (WIDL) is being proposed. It is an application of XML with the aim of: "enabling the automation of all interactions with HTML/XML documents and forms, providing a general method of representing request/response interactions over standard web protocols". The paper: "WIDL: Application Integration with XML" describes the approach.

A note to the XML developers list from Robin Cover (who provides excellent reviews of XML developments on the OASIS web site) addresses concerns from developers regarding the usability of W3C's 'XML Schema' formalism:
"Does it attempt too much? Is the spec hard to understand? Is the notation excessively verbose?, etc. Despite these doubts, the WD specification seems to make sense to a growing number of developers. I note (anecdotally) that W3C XML Schema (.xsd) is used as the principal meta-level specification in two important projects, announced recently: 'DIG35: Metadata Standard for Digital Images'; 'Universal Description, Discovery, and Integration (UDDI)'. These are not lightweight or trivial XML applications."

The registry application has been developed by Documentum and Sun Microsystems. Documentum's 4i eBusiness Edition powers the entire process from schema submission, through approval, to its public availability on the web site.

Roger L. Costello has summarised the "XML Schemas: Best Practices" discussions emanating from the XML developers mailing list and published them on the web at the address below.
A W3C Note proposes Document Definition Markup Language (DDML), as the schema language for XML documents. The note states that: "DDML encodes the logical (as opposed to physical) content of DTDs in an XML document. This allows schema information to be explored and used with widely available XML tools. DDML is deliberately simple, providing an initial base for implementations. While introducing as few complicating factors as possible, DDML has been designed with future extensions, such as data typing and schema reuse, in mind".
Document Structure Description (DSD) is being put forward as a way for describing XML documents. This schema language is result of a research collaboration between AT&T Labs, NJ and BRICS at the University of Aarhus, Denmark. The DSD language arose out of a need to describe XML documents to web programmers with an elementary background in computer science. DSDs have also been expressively designed to further W3C sponsored XML technologies such as Cascading Style Sheets (CSS) and XSL Transformations (XSLT). The authors claim that: "DSDs require no specialised XML/SGML insights. The technology is based on general and familiar concepts that allow much stronger document descriptions than possible with DTDs or the current XML Schema proposal". The group is offering:
- a detailed, complete, and tested DSD language description;
- an introductory article;
- free source code;
- a meta-DSD that completely accounts for the syntax of DSDs;
- an XSLT pretty-printer that converts DSDs into hyper-link HTML;
- a preliminary industrial case report, where we discuss the use of DSD to describe XPML, a variation on HTML for interactive voice services.
The developers are encouraging comments and suggestions for further development, for more information visit the DSD web site.
Two developers have defined MusicML specifically for sheet music. Based on XML the authors have also written a MusicML browser in Java to display their efforts. Their goal was not to define a sheetmusic specific language, but rather to provide an application with which to explore the capabilities and limits of XML. The complete listing of the MusicML DTD, the rationale for it's development along with key findings and examples of code are published.
The Voice eXtensible Markup Language Forum is developing the VoiceXML specification, an XML-based markup language that is aimed at enabling voice access to web content and services. AT&T, Lucent and Motorola have contributed their respective phone and voice markup languages to help the Forum create a specification "leveraging the best of these technologies". Whilst IBM is included in the list of companies involved, contributing its Speech Markup Language technology (see items below). The VoiceXML specification provides a high-level programming interface to speech and telephony resources for application developers, service providers and equipment manufacturers. The latest version of the specification is available for review via the Forum's web site.
Voice XML explained
IBM developerWorks has an article on Voice XML.
URL: http://www-4.ibm.com/software/developer/library/cl-voiceact.html?open&l=136,t=gr,p=x.vWeb
IBM is developing the use of XML to define a new Speech Markup Language that will deliver speech capabilities to web browsers. SpeechML is available for download and is being incorporated into the VoiceXML specification (see above).
The intention of the VoxML markup language for voice applications is to enable developers to add speech interfaces to web applications or content. The VoxML language is an application of XML. In essence VoxML applications are written in the form of dialogues - allowing users to interact naturally with the application. These dialogues are interpreted by voice browsers in much the same way as HTML pages are interpreted by today's web browsers. The intention is to enable users to connect with web content from telephones and voice-enabled devices. More detailed information concerning the VoxML language is available on the VoxML web site.

XSL is a proposal to the W3C to provide style sheet information for eXtensible markup language (XML) data. XSL extends beyond Cascading Style Sheets (CSS), enabling developers to handle the full richness of XML data and documents.
CSS (see below) can remain the style sheet language of choice for HTML and simply structured XML documents. Whilst XSL could be used for formatting highly structured XML data, especially where the data's presentation order may change between delivery and display. For example, a table of stocks, stock prices and trading information might be sent to a browser using XML. Using an XML-enabled browser users could sort, filter and display the stock information based on their own preferences.
XSL joins Cascading Style Sheets (CSS), the other W3C-developed style sheet language implemented in current popular browsers, as part of the W3C Style Sheets Activity. W3C will be developing both the XSL and CSS style sheet languages in parallel. CSS is used to style HTML and XML documents on the Web. In addition to styling XML documents, XSL is also be able to generate new XML documents from XML data.
The XML.com website focused on whether there was a need for the style language XSL, by asking questions such as: How necessary is XSL? Is it just too complicated? Is it really an improvement over what we have today? Might XSL even be considered harmful to the Web?
An article, entitled: "XSL Considered Harmful" provided a controversial view, although the sentiments expressed have a resonance with many in the XML developer community. An online debate was held, and is summarised, at the site based on issues raised in the article. The site also features links to previous coverage of XSL including a tutorial which introduces the technology.

CSS2 offers precise control over the presentation of Web pages, adding: improved printing, positioned and layered elements, improved Internationalization, and a rich WebFont model, including downloadable fonts. CSS2 can also control voice, pitch, stereo position and other aspects of how Web pages will sound when rendered to speech.

Miloslav Nic of the Department of Organic Chemistry, ICT Praguehas published the first version of his CSS2 tutorial on the Zvon site. It contains at this moment around 50 XML sources with around 100 simple stylesheets. The Mozilla browser is required to view the examples, the author is planning support for "other browers (ie. Internet Explorer) when they reasonably support CSS2".

The Organization for the Advancement of Structured Information Standards (OASIS) runs a web site called XML.org which will act as an: "open industry XML registry and repository offering automated public access to XML schemas". OASIS hopes that the registry/repository will play an "enabling role in the use of industry-defined XML applications for electronic commerce, business-to-business transactions, and tools and application interoperability".
XML.org, includes an XML Specifications Catalogue, a comprehensive list of XML specifications currently under development including links for more information. There is also a specification submission form on the site, to encourage and enable organisations to share their XML specifications with the community at large.

Anders Moeller and Michael I. Schwartzbach of the BRICS research center, University of Aarhus, Denmark have sent a note inviting readers of El.pub to view their "comprehensive slide collection providing an introduction and technical overview of XML and related technologies". The tutorial gives a thorough tour of:
- XML, both a concrete and a conceptual description;
- Namespaces, about avoiding nameclashes in markup;
- XLink, generalizing the HTML link model;
- XPointer, for fine-grained addressing in documents;
- XPath, used extensively in both XPointer and XSLT;
- DSD, a simple but powerful schema language;
- XSLT, for making transformations of XML documents;
- XML-QL, query languages generalizing SQL to XML.
Furthermore, the tutorial contains selected links for more information about each topic. The slides are designed with concrete motivation and technical contents in focus, for the reader who wishes to understand and actually use these technologies.
XML4SE is a web site dedicated to XML applications in Software Engineering that presents documents and links on XML projects related to software development activity. In particular, meta-languages that catch core information of code or models are recorded (eg. JavaML, OOPML, XMI, UXF).

The HTML Writers Guild is a not-for-profit, 125,000 strong international educational organisation of HTML authors. Project Gutenberg is an organisation founded by Michael Hart in 1971 to record the worlds great literature as ASCII text. To date almost 10,000 volumes have been marked up.
"Gutenberg at HWG" is a joint initiative of these organisations to convert the ASCII texts to XML. The project is currently carrying out a "proof of concept" trial, involving the mark-up of about 30 books, with a further 50 or so in the pipeline. The project is looking for people to take an active role in helping it develop suitable DTDs, and to contribute their expertise, especially individuals who would be interested in supervising XML markup in languages other than English, and in non-roman character sets.
Frank Boumphrey, Director Gutenberg@HWG is interested to hear from anyone who is interested in getting involved with the project. The project operates two mailing lists, subscribe at the site below, which cover general: discussions of markup; and the design of suitable DTD's for marking up historical documents.

EDI and XML
There is considerable interest in the potential utility of XML in the area of e-commerce, the majority of whose transactions could ignore traditional EDI mechanisms altogether. The EDI/XML Group are working on ways to develop a framework to enable EDI applications based on XML. The role for XML in E-commerce is covered on the E-commerce topic page on this site.
The Apache XML Project is an open source software development initiative, building developer tools that make the adoption of XML an easier process for information architects, web designers, and application providers. The project has received quite a boost from the commercial vendors in the space, through the provision of software source code from both IBM and Sun. The stated aims of the project are to:
- provide commercial-quality standards-based XML solutions that are developed in an open and cooperative fashion;
- provide feedback to standards bodies (such as IETF and W3C) from an implementation perspective;
- be a focus for XML-related activities within Apache projects.
The intention of the project is to operate as a meritocracy, developing software based on the open source "model". To get involved join the mailing lists on the project web site.

Weave is a site devoted to publicising sites and documents created in XML. Web sites built using XML can be added to the directory on the Weave site.
Kweelt is a Java framework to query XML data. Among other things, it offers an evaluation engine for the Quilt XML query language. This is the first implementation of a query language for XML that answers all the use-cases published by W3C for the XML query requirements. Kweelt is not just an implementation of a query language. It has been designed as a reference platform to make all sort experiments related to XML: storage, optimization, benchmarking, document output, etc. The software is free and open-source (GNU GPL license) to allow people to make more radical changes to the framework itself. For more information and to download the binaries and source, go to the Kweelt page below.

The Infozone-Group has initiated a new project called Lexus, aiming to specify "an open standard for an XML Update Language". The group believe that in their opinion, "there is the real need for this specification, because all available implementations of query languages and whitepapers about 'Query Requirements' don't speak about updating XML data sets via an API".
They are looking for interested people to participate in the development, further details from the project web site.
XMLPatterns.com has announced the public launch of its web site. The site is dedicated to XML structural patterns which "describe known solutions to a problem in a particular context". Patterns have been used successfully in the past by the object oriented software community. These patterns are similar, but deal with designing XML documents.
The Sun Java API for XML Parsing (JAXP) Optional Package provides basic functionality for reading, manipulating, and generating XML documents through pure Java APIs. It is a thin and lightweight API that provides a standard way to seamlessly integrate any XML-compliant parser with a Java application. Depending on the needs of the application, developers have the flexibility to swap between XML parsers (such as high performance vs.memory conservative parsers) without making application code changes. Thus, application and tools developers can XML-enable Java applications "for e-commerce, application integration, and dynamic web publishing".The reference implementation uses the Java Project X as its default XML parser. However, the software's pluggable architecture allows any XML conformant parser to be used.
The Python XML Special Interest Group develop the Python/XML distribution which contains the basic tools required for processing XML data using the Python programming language. The distribution includes parsers and standard interfaces such as SAX and DOM, along with various other useful modules. The code is being developed bazaar-style by contributors from the Special Interest Group, so please send comments, questions, or bug reports to them.
