In turn, this causes
specifications to be created with a certain lack of practical experience, which in turn shows
in the quality of early specification versions and again hampers adoption.
If models can be provided that collect the basic ideas of the standard and completely hide the
implementation details, companies could start today with integrating the existing standards.
A model-driven approach seems to be the most appropriate way for this task: The conceptual
tasks could be modeled on a meta-level by using a simple and abstracted modeling technology,
and some kind of transformation engine would take these models and either directly
execute them or transform them into executable code. In this way systems could be easily
upgraded to new versions of specific Web Service technologies, as the meta-models will
probably only change in minor ways or not at all.
A Web of Services thus could become a tangible possibility. This could be the next important
step for Web technologies??”because Web services possess many powerful features ideally
suited for industrial use and commercial success stories. This also could build the momentum
to ensure the wide-spread use of, in our point of view, a very important technology.
