RDL/TT - A Description Language for Profile-Dependent Transcoding of XML Documents

With the increasing availability of various web-enabled mobile devices, content has to be effectively adapted to their different limitations. So, web content need rearrangement, i.e., a transcoding, to better fit on small displays when, for instance, layout specific HTML structures like tables and frames are used. In this article, we present a description language to define generic rules for this purpose and introduce RDL/TT (Rule Description Language for Tree Transformation). RDL/TT specifies sets of transcoding functions generic to user and hardware profiles. A Java-oriented syntax is used to describe the transcoding functions which operate on the DOM (Document Object Model) tree representation of an HTML or XML document.
