Abstract: 

Service composition is currently done by (hierarchical)
orchestration and choreography. However, these approaches
do not support explicit control flow and total compositionality,
which are crucial for the scalability of service-oriented systems.
In this paper, we propose exogenous connectors for service
composition. These connectors support both explicit control flow
and total compositionality in hierarchical service composition.
To validate and evaluate our proposal, we present a case study
based on the popular MusicCorp.
