Designing Semantic Web Service Based on OAS 3.0 through Relational Database

The web service description becomes the interface that must be provided by the service provider to expose the web service capabilities it offers. To increase human and machine understanding of web service descriptions, it is necessary to add meaning that can avoid ambiguity and ease of learning by clients who do not have sufficient knowledge. The semantic web is becoming a technology that can be adopted to assign meaning to resources described in service descriptions. Collaboration between web service description and semantic web presents a new term known as semantic web services (SWS). In service composition domain, SWS become crutial elemen to support automation in service discovery and selection. The complexity of creating web service semantics is caused by, among others, difficulties in identifying resources, the relationship between resources, and determining the knowledge that should be added. This study contributes to the activities used to create web service semantics from the OAS 3.0 document. OAS 3.0 is a standard that is widely adopted today by web service developers using the REST architecture. As a result, the RDF scheme can be structured by following the activities and techniques presented in the research methodology.
