Service-oriented computing has received significant attentions recently, and many applications are being developed using this approach. Thus there is a need to analyze system requirements. SORE focuses on modeling, specifying, and analyzing application requirements for software that will be developed in a service-oriented manner running in an SOA infrastructure.

SORE is an important topic in Service-Oriented System Engineering (SOSE) and is an emerging area. Requirement engineering has evolved from classical methods such as SREM, to OO methods using UML, and to SORE. Several projects have initiated in this direction.

SORE differs from traditional requirement engineering as it assumes that the concerned application will be developed in an SOA framework running in an SOA infrastructure.
