An XML Interchange Format for Wiki Creole 1.0

Authors: Martin Junghans, Dirk Riehle, Umit Yalcinalp

Abstract: Wikis have become an important application on the web and in the enterprise, yet there are no interoperability standards between different wiki engines. We present the first complete XML representation format of Wiki Creole 1.0. Wiki Creole is a community standard for wiki markup, the language used to write wiki pages. This report presents the complete XML representation format using a validating XML schema. In addition we present XSLT definitions for transforming the XML representations to XHTML on the one hand and for transforming the XML representations to Wiki Creole markup on the other hand. Our work shows how using XML technologies we can make wiki interchange, wiki upgrading, and wiki conversion independent from a specific wiki engine implementation.

  1. Hey James, you are fast to have discovered this whole site remake 🙂 Thanks for the first comment on this blog!

    As to your question: We were thinking about JSON too but stuck with XML (despite all the critique) hoping our standards expert at SAP Labs could guide us through a W3C process.

    Still, you need to JSONify Creole, which is a big part we did with the XML spec. I think it would be straightforward (and sometimes simpler, think arrays) to turn the XML spec into JSON objects.

  2. Hi Dirk, I’m working on a MediaWiki to TikiWiki importer as part of my Google Summer of Code 2009 project (http://dev.tikiwiki.org/gsoc2009rodrigo). I plan to use PEAR::Text_Wiki which might help in conversions between TikiWiki and Wiki Creole as there is a recent PEAR::Text_Wiki_Creole package.

    I have interest in the XML Interchange Format but I don’t I will be able to implement support for this format both for TikiWiki and for MediaWiki in this project unfortunately.

    I’m writing because I would like to know the status of the project and if there are some working implementations of it. Thanks, Rodrigo.

  3. Hi!

    This looks like a fantastic format. I’m starting to get into Creole as the closest I can find to a standard Wiki format, and an XML version of it is a great idea. I just wish I’d thought to look for them before wasting time making up my own lesser formats first.

    I can’t seem to find a license for this XML format. Is it freely available for anyone to use, or do you intend to license it out?

    Thanks,
    Zoe.

  4. Hi Zoe,

    files are licensed under the AGPL, as shown on SourceForge. Unfortunately, this particular code base is not under active development at present; I do hope to restart it though under a new umbrella, my new job, that is http://osr.cs.fau.de

    Cheers,
    Dirk

  5. Wow, thanks for the quick reply! That’s OK about the development, I was going to write my own code anyway (I need it to run in PHP, not Java). It’s just nice to know there are existing standards for the formats themselves that I can work with.

    If I get my code working, I’ll be sure to publicly release it under a similarly liberal license.

    Thanks again,
    Zoe.

  6. Hi again!

    Thanks for the help. I’ve now tentatively released the work-in-progress of my Creole conversion class. It’s available at http://bytenoise.co.uk/creole.txt to anyone who’s interested in using it.

    It’s very basic at the moment, not implementing the whole spec, but it’s a start. I’ve released it under the AGPL — I hadn’t realised such a license exited until you pointed it out to me, so thanks for that information too!

    Zoe.

  7. Hi!

    Sorry to keep pestering you like this, but is there any chance you could suggest CreoleXML tags to support Creole’s additions such as indentation for quoting, superscripted text and subscripted text? I’m working on getting various historical books translated into Creole format, then from there to CreoleXML and finally from that to a variety of other formats, but in order to proceed I need to either find or create a version of CreoleXML that supports these three additions. Any support in the way of an updated CreoleXML spec, or permission/blessings to make my own, would be much appreciated.

    Thank you,
    Zoe.

    PS My parser is coming on nicely so far and is available from http://sourceforge.net/projects/phpcreole/ should you wish to use it.
