TECFA's XML Page

"XML" means "Extended markup language". XML is designed as a machine readable self describing text editable persistent store for data. It (hopefully) will replace HTML in many cases ! Note that this page is NOT indented to be one of THE indexes, but it reflects our own needs and interests. Only updated whenever I feel so :)

XML @ TECFA

Teaching XML @ TECFA

• See under XML Trail of TIE slides (in French)
• Locally made examples: simple XML and XSLT (browser the directory). Some stuff will not work (because old)

Software installed at Tecfa

• Not sure that this is up-to-date: see all the entries of this page :)
• Server-side we mostly use php/xml, php/xslt, Cocoon 1. For batch processing xerces/xalan/fop and saxon
• Validator Win/Unix: xmlTester.jar (works with hte Xerces parser).
• XML Nanny. XML Nanny is a Free Mac OS X developer tool that provides an Aqua interface for checking XHTML and XML documents for Well-Formedness and Validity either locally or across the network. (Tiger OS X 10.4) [sept 2005]
• Validator Unix: xmllint (works with the Gnome libxml library from the XML C parser and toolkit fo Gnome. Installed automatically when libxml2 library is installed)
• XML Editing: PSGML with Xemacs 21.x. For people afraid of Emacs we use Xerlin and XEdit).
• DTDparse (locally installed in /local/filters/dtdparse). See the short local doc. We use it to generate an HTML tree from a DTD.
• DTDDoc - Javadoc for DTD's
• Matra - An XML DTD Parser Utility. Free Java-based tool. See e.g. the one for SVG
• Parsing a DTDIncludes Java/PHP/Perl code
(Webreference article in several installments. You also have to find column column68 and previous ones maybe).
• Xtract: a `grep'-like tool for XML documents Locally installed (maybe OLD) documentation

R&D and plans

• Student Project management with XML: If you read french, you can dig in my STAF-18 class. A first pilot XML project that went rather well in Spring 99. A project mangement DTD, and a little server-side code. A new version exists now as ePBL module used in our PostNuke teaching portal, e.g. see staf18iris (You can get this from TecfaSEED) and consult Vivian's portal.
• Replace structured HTML contents by XML and build smarter information webs.
• Use XML to display some database contents (with server-side technologies or JAVA applets), also use XML databases like eXist to store XML data (make some tests)
• RDF/OWL and TopicMaps for information networks
• Specialized XML markup languages for different tasks, e.g. documents for teachers like the TECFA SEED catalog (made with DITA)

Documentation & Validation

On-line Validation

• W3C HTML Validation Service This validator doesn't always work with your own DTD's. Its primary function is to validate W3C vocabularies (HTML, XHTML, SVG, MathML, ... )

• XML Information Set (specification describing an abstract data set containing the information available from an XML document)
• By default XML uses UTF-8 characterset. See Unicode in XML and other Markup Languages (W3C Technical Report)

Specifications (and proposals) for XML Applications

This just contains some major very technical applications. See also other Toolbox sections, e.g. SVG, XSL(T).

• Compount document formats (Overview Page)
• Compount Document by Reference Framework (CDRF). A CDR is a document which logically includes other documents via a hypertext reference. For example, XHTML-formatted content can be augmented by SVG object. (Working Draft in aug 2006)
• WICD Core, based on XHTML, CSS and SVG. .. integrating existing markup language formats in preference to inventing new markup (Working draft in 2006)
• WICD Full, The WICD Full 1.0 profile is designed to enable rich multimedia content on desktop and high capability handheld agents.

• XQuery 1.0: An XML Query Language (the central document)

• XML Linking Language (XLink) W3C Recommendation 27 June 2001

IT separates presentation from content, allows reuse, gives strong typing, reducing the number of round-trips to the server, as well as offering device independence and a reduced need for scripting. XForms is not a free-standing document type, but is intended to be integrated into other markup languages, such as XHTML or SVG.

• Comparison and Benchmarking of Native XML Databases Abstract by Anand Vivek Srivastava (PDF)

Browsers and plugins (client-side XML)

• Microsoft Internet Explorer. Get IE 6 !
• Firefox and mozilla implement CSS2 (client-side XML with CSS) and XSLT. The Mozilla is at http://www.mozilla.org/. Always get the latest version, some XSLT support always has been shaky (I will remove this statement once it can do DITA stylesheets)
• Opera has similar functionality as Mozilla does. But you have to pay a bit if you want the advertizing-less version.
• Safari (Max). Get the latest verion (XSLT is only supported since fall 2005)
• Other, more experimental browser like Amaya have various forms of XML support (needs some updating here)

On-line Tools

• XML Utilities at HitSoftware, e.g. XML->DTD or XML->XMLSchema
• XML Schema Validator, XML Output version. The program used is xsv by H. Thomson and R.Tobin, Univ. of Edinburgh
• For XML/DTD on-line validators, please consult major XML sites....

Editors and editor libraries

Text Editors with a GUI

• FrameMaker 7 Very good SGML and XML text processor (needs a LOT of configuration work and is quite expensive, but I like it nevertheless). Note: Version 7 is a lot more XML friendly than V6 (FM + SGML). Major problem I found is mapping of internal objects (XRefs, Tables, Figures) to certain DTDs. E.g. one can't map XRefs to non-empty elements without C programming :( See also my documentation on old FrameMaker+SGML 6 + XML. Some of it is still useful for version 7.
• Abortext, one of the real XML players has real tools (e.g. Epic) that get decent reviews (but I did not test any). Price: over $1000
• EditX. Quote from an email: "EditiX is a cross-platform powerful and easy to use XML editor [...] and XML-related technologies such as XSLT / FO and XSD Schema. EditiX provides users with an extensive range of XML functionality within a refined IDE that guides you with intelligent entry helpers. EditiX has realtime XPath location and syntax error detection. Helpers are also provided with context syntax popup supporting DTD, Schema and RelaxNG. EditiX supports multiple templates and project management. User can apply XSLT or FO Transformation and show the result with a dedicated view. All the process can be managed by shortcuts. EditiX includes default templates with XML, DTD, XHTML, XSLT, XSD, XML RelaxNG, SVG, MathML and XML FO." NOT TESTED @ TECFA so far 1/2004.
• Hypervision sells WorX SE, a plugin for MS Word (evaluation copy available, not tested)

• Cooktop Win, needs IE5.x, FREE (looks ok, but not tested here / jan 2003)
• Jaxe, votre éditeur XML (French) free Schema-aware XML editor (comes preconfigured for a teaching-oriented Schema and XHTML, you can change this by defining your own xsd and then edit a short configuration file to map XML Schema tags to Menus. User can then select from environment. Not tested in production, but I like the concept (DKS Mai 2002). Missing is a contextual "right-click" insert (unless I didn't see it)
• Serna. Commercia WysiWyg XML Editor. Support for DocBook, TEI and Dita. Win/Unix. Specifications look good, but NOT TESTED @ Tecfa. Cheap Academic Prices ($45). [2/2004]

Tree/Text/Structure Editors with a GUI

• oXygen Tree/structure editor Quote from an Email message: "<oXygen/> XML editor covers all the today's XML technologies offering support for any XML document, working with XML Schemas, DTDs, Relax NG schemas and NRL Schemas. The powerful transformation support allows you not only to edit XSLT and XSL-FO documents but also to obtain documents in the desired output format like HTML, PS, PDF, etc. with just one click. " (NOT TESTED @ TECFA !) /1/2004)

• Exchanger XML Editor, cheap ($130) commercial structure and tree editor, multiplatform (2003/V3.x 2005) - Not tested.
• Xerlin Opensource Extensible XML Modeling Application. This used to be "Merlot" which is no longer available from its original place. (Used at TECFA for data-centered XML editing by people who are afraid of Xemacs - 12/2002). So it's a tree editor (and I don't like them).
• Lucid'XML editor. Free (?) tree and source editor (oct 2002, not tested). Multi-lingual, Java/Tomcat/IE5.5+ based

A simple XML editor for wellformed documents. Reads/uses a DTD somewhat (lists all tags). HINT: to get a hint from the DTD start typing. e.g. "<". Has Emacs or Win keybindings. Good for people who dont want to install Emacs.
  INSTALLED at TECFA, type 'xed' in a Unix Window.

• xmlwebgui, Web-based (Dom-conformant) validating xml-editor (alpha in 3/2002). Way to go for editing of portal contents :)
• xmloperator Free XML tree editor, Java-based, DTD or Relax aware (v. 2.3 sept 2003)

TTW Editors

• See for the moment: TTW WYSIWYG Editors (very good index)

Emacs modes

• PSGML: DTD supported editing (and validatation with an external program) we use is based on the PSGML mode. It's a powertul context sensitive tool, look at the Manual. Also, Bob DuCharme has a good page with PSGML tricks. Markus Hoenicka's SGML for NT page may also be of good help (dig a bit)..
  A patched PSGML mode with XML support is included in Xemacs 21.0 (used @ TECFa and by myself, works great on Unix and Win95/98/NT)
• nXML is James Clark Emacs mode for Relax NG schemas. Here is a short article from XML hack. Read The Design of RELAX NG if you want to know why you may want to use Relax NG.
• Not tested: sxml-mode for (X)Emacs

XSL(T/FO) engines

• The Apache XML Project. In particular Xerces (XML Parser), Xalan (XSLT engine), FOP (XSL-FO->PDF engine) and Cocoon (publication framework) Note for Tecfa users: Under Unix you can use "fop xmlfile xslfile pdfoutput" or "xslide xml xsl xxx" (xalan) to do command line processing.
• SAXON XSLT and XQuery Processor INSTALLED and used as default XSLT engine at Tecfa. Saxon has additional features that others (Xalan) have not. documentation at saxonia.com ( local pwd protected!).
• XT, James' Clark implementation of XSL transformations. (needs a SAX parser like his XP).
• RenderX! has a good Fo2PDF commercial product. At Tecfa we use Apache/FOP which is free.

Server-side XML and databases

• SEE also Xquery / Xupdate / XML databases and Portals @ TECFA Page

• X2X XML Link Engine. "allows linking between documents and information resources without needing to change the resources that are being linked" (not tested)
• SDX. Good and free french XML search tool, multilingual support. (doc in french, but API doc in English). SDX comes as a *.war file. Configuration requires xsd editing.
• 4suite.org/ has "open source" XML processing tools and an XML data server (Python based, not tested 3/2001, but looks promising)
