| Research Abstract |
We developed an extensible component description language named SCL(Software specification and Commerce Language). SCL can describe both interface specification and commerce information. For interface specification, SCL can describe the interface signature based on CORBA IDL as well as. interface semantics by contract and interface context by means of Design Patterns. SCL is based on HTML/XML so that it can present the information on the Web. Semantics of the component interface is described by a static structure around the component with a class diagram and by the dynamic behavior with a sequence diagram.
We also proposed a SCB(Software Commerce Broker) to collect, present, and retrieve components information described with SCL, and developed a prototype of the SCL.Among the functions provided in the SCB, SCL editor helps the users to describe the components interface and an internet agent can collect the component information from the Web sites around the world. We collected some 1,6000 components information and evaluated the effectiveness of the SCL and SCB.
