   Dear colleagues,

   This  week  we  welcome once more a student from Universiteit Utrecht.
   Martin  Bravenboer has been working on the relationship between ATerms
   and XML.

                        ATerms and XML with Stratego

   Date:    30.05.02
   Time:    10:00
   Venue:   M279
   Speaker: Martin Bravenboer
   Title:   ATerms and XML with Stratego

   The  XML standard is widely used as a syntactical standard to exchange
   data in ASTs between components. In this way we can compare XML to the
   ATerm  library.  I will discuss future tools for the mapping of XML to
   ATerms,  with  as  the  main  goal to use Stratego as a transformation
   language for XML.

   Mapping  XML  to  ATerms  is  despite  their  common usage not trivial
   because of the more untyped and semi-structured nature of XML compared
   to ATerms and the few features they don't have in common.

   To  overcome  problems  in  parsing  XML I suggest a mapping to ATerms
   based   on  existing  XML  parsers.  The  tool-set  still  requires  a
   handcrafted  'atermification'  of  the result, but I will discuss some
   possibilities  to  generate  this  atermification,  it's inverse and a
   Stratego signature from a schema in an XML schema language.

   Finally  I  will  discuss a few applications of XML transformations in
   Stratego. An interesting application from the XML point of view is the
   mapping  of XML to application objects with the use of concrete syntax
   and Stratego or XSLT.

   Have a nice day.

   The  programming environment meetings are a forum for the presentation
   and  discussion  of  new  ideas,  ongoing and finished work. A typical
   meeting  addresses  a subject in the area of programming environments,
   program  generation, algebraic specification, term rewriting, parsing,
   etc.  A presentation ideally takes between 45 and 90 minutes. Meetings
   taking  longer  than 45 minutes are interrupted by a coffeebreak. Most
   Thursdays,  a  meeting is held which starts at 10:00 am. in one of the
   rooms at CWI/WINS. Exceptionally, dates or times may change.

   The    program    of    the    meetings    is    available   on   WWW:
