Abstract:
The usage of abstract XML layout languages has proven an effective technique of agile, adaptable and
multi-channel multimedia publishing. This general strategy employs an XML definition file specifying
graphical widget layout and relative disposition regardless of specific presentation medium. This strategy
has been successfully applied for WWW, MHP, WAP, PDA and in many media platforms and there exist
several existing proposals and implementations. However, not many general formal strategies have been
developed to address some XML-based layout language design challenges such as general structure,
validation and schema development. Additionally, there are some implementation issues that many such
techniques fail to address properly. In this paper, a simple yet powerful general strategy of solving these
issues is described: the XSD standard is leveraged to help in designing and validating XML layout
languages as well as aiding in the development of GUI layout applications. Th
is strategy is proposed as a
practical approach valid in large-scale publishing environments.
