Web mashups are Web applications developed using contents and services available online. 2Mashup3 has become one of the hottest buzzwords in the Web applications area, and many companies and institutions are rushing to provide mashup solutions. Even though semantic discovery has not yet matured, its state-of-the-art not only can contribute to streamlining mashup discovery but can also enable a higher degree of automation in mashup development. JOpera is one of the efficient mashup development or service composition tools. JOpera’s integrated development environment (IDE) is used for rapid prototyping and development of workflow processes. The IDE is implemented on the Eclipse platform as a set of plug-ins. JOpera calls specific service providers to achieve certain atomic or composite tasks. It does not provide choices for user needs (goals) from multiple alternative service providers. It lacks automatic discovery based on user goals. The best option to provide automatic service discovery is using semantic web services. The thesis proposes a novel framework aiming to extend JOpera by adding new capabilities for semantic web service discovery using the discovery framework of the reference model of semantic web service execution environment (WSMX). The framework employs WSMX as a middleware to support semantic discovery of web services based on goals passed by JOpera as frontend. Therefore, the power of SWS discovery and composition was added to the mashups built by JOpera.
