Adapting Web Services for Multiple Devices: a Model-Driven, Aspect-Oriented Approach

Abstract

Mobile devices have become  an essential element in  our daily  lives,
even    for connecting  to the   Internet. Web  Services  have  become
extremely  important when  offering services  through   the  Internet.
However,    current Web   Services  are  very inflexible  as  regards
their  invocation  from different types  of  device, especially  if we
consider the  need  for  them  to   be adaptable  when  being  invoked
from   a    mobile   device.  In    this   paper,   we    will propose
several  alternatives for  the  creation  of  flexible   web services
which   can  be  invoked from   different  types    of   device,   and
compare   the    different   proposed  approaches.  Aspect   -Oriented
Programming   and  Model-Driven   Development  have been  used in  all
proposals to reduce the  impact of service adaption,  not only for the
service developer, but also to maintain the correct code structure.
