    XML Processing in Prolog: A tutorial at Extreme Markup Languages 2005
    August 1, 8:30 AM-5:30 PM, Hotel Europa, Montreal, Canada

    The XML of Programming Languages

    The great appeal of XML for representing documents, business and
    scientific data has its basis in a particular philosophy for
    organizing work. As an XML user, you already understand the power of
    describing things in terms of what they are, rather than how they look
    or behave. You appreciate the flexibility gained by decoupling
    definitions and descriptions from the details of how those data are
    expected to be processed.

    What would 'the XML of programming languages' be like? One answer,
    of course, is that such a language would be an XML application itself,
    capable of being processed just like (or even along with) other XML
    markup.

    This tutorial invites you to consider another answer: instead of a
    programming language expressed *as* XML, we'll introduce one designed
    around similar principles to those of declarative markup. Prolog was
    developed at the Universities of Aix-Marseille and Edinburgh in the
    early 1970s -- around the same time Charles Goldfarb was inventing
    SGML at IBM. Colmerauer, Kowalski, and Roussel originally designed
    Prolog to support research in natural language processing. It should
    therefore come as no surprise that Prolog offers many benefits for
    processing artificial languages, such as those expressed in XML.

    Processing XML in Prolog

    This tutorial will be an introduction to logic programming and to
    problems, issues and strategies for XML processing in the Prolog
    language. It is intended for experienced programmers who are familiar
    with XML, but who have had little or no prior experience with
    Prolog. You'll learn how document processing problems are addressed in
    logic programming as compared to conventional procedural languages. A
    programmer's introduction to Prolog will be followed by topics such
    as:

    * Strategies for parse tree representation
    * Working with XML namespaces
    * Reasoning about Documents: Syntax versus Semantics
    * Dealing with overlapping hierarchies

    Prolog is particularly useful for developing new XML processing
    approaches, but it can be as efficient as other high-level languages,
    even for routine transformations of XML.

    My parents took me to the Semantic Web, and all I got was more markup

    Some of the most celebrated XML-related developments in recent years
    have focused on enriching markup languages with more expressive
    semantic information: technologies like RDF, Topic Maps, and web
    ontology languages all aim to bring knowledge representation to the
    World Wide Web. So once you've got rich semantic information in a form
    you can manipulate with XML processing tools -- what then? Prolog's
    built-in inferencing capability provides a starting point for building
    programs that reason with and about structured documents.

    Extreme Markup Languages 2005

    XML Processing in Prolog will be offered at Extreme Markup Languages
    2005. The instructor will be David Dubin, a research scientist at the
    University of Illinois at Urbana-Champaign. Extreme Markup Languages
    is devoted to the theory and practice of markup languages from
    industrial, academic, and other points of view. Further information
    (including registration for the meeting and this tutorial) can be
    found at
