Description

Building applications by composing pre-developed
components has promise for reuse and software
engineering industrialization. Model-Driven
approaches not only elevate the abstraction of the
development, but also leverage the integration
tools for various supporting functionality such as
analysis, transformation, simulation, optimization,
and monitoring. A transformation framework, called
Regular Expression Language is used for
integration of service components. The integration
requirements are depicted as a graphical process
model and then are transformed into Business Process
Execution Language (BPEL). We solved the theoretical
difficulty to generate non-exponential BPEL when the
process model presents irreducibility. We also
present a Model-driven Domain-specific Integration
Language to integrate the source or binary
code of the software components. Two-Level Grammar++
is used to specify feature models so that
the integration requirements can be validated
against domain feature model specification.
Glue/wrapper code generation is discussed for
integrating heterogeneous components.
