Previous issue date: 2013-12-12 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Web services are computational solutions designed according to the principles of Service
Oriented Computing. Web services can be built upon pre-existing services available on the
Internet by using composition languages. We propose a method to generate WS-BPEL
processes from abstract specifications provided with high-level control-flow information.
The proposed method allows the composition designer to concentrate on high-level specifi-
cations, in order to increase productivity and generate specifications that are independent
of specific web services. We consider service orchestrations, that is compositions where a
central process coordinates all the operations of the application. The process of generating
compositions is based on a rule rewriting algorithm, which has been extended to support
basic control-flow information.We created a prototype of the extended refinement method
and performed experiments over simple case studies / Os servi?os web s?o solu??es computacionais criadas de acordo com os princ?pios da Com-
puta??o Orientada a Servi?os e disponibilizadas via Internet. Novos servi?os web podem
surgir a partir outros pr?-existentes, utilizando linguagens de composi??o. Considerando
orquestra??es de servi?os, onde existe um processo central que coordena todas as opera-
??es da aplica??o, propomos um m?todo para gera??o de processos WS-BPEL, a partir de
especifica??es abstratas dotadas de informa??es de controle. O m?todo proposto permite
ao projetista da composi??o se concentrar em especifica??es de alto n?vel, aumentando
sua produtividade e gerando especifica??es independentes de servi?os web espec?ficos. O
processo de gera??o de composi??es se baseia em um algoritmo de reescrita de regras, que
foi estendido para dar suporte a informa??es de controle b?sicas. Criamos um prot?tipo
do m?todo de refinamento estendido e realizamos experimentos sobre estudos de caso
