The field of service-oriented computations is actively developed in today’s world of information science. Tasks, which require use of multiple services, arise constantly. The combination of multiple services for the solution of a problem is called service composition. Dependencies between services can be usually described with the directed acyclic graph (DAG). There are a lot of ways to define service compositions; most of them use the graphic interface software or various markup standards. However, it is a common situation when it is convenient to define the composition of services as a piece of program code, at the same time the processing of intermediate service results and extraction of service dependencies graph should be available.
