The data in different clinical information systems silos are in multiple formats, and
relevant medical and healthcare knowledge must be accessible in a timely manner.
This can be performed through interoperability standards which can enable information
integration, ???providing transparency for healthcare-related processes involving
all entities within and between hospitals, as well as stakeholders such as pharmacies,
insurance providers, healthcare providers, and clinical laboratories??? (Singh
et al., 2005, p. 30). The main standard for interoperability in the Semantic Web is
Resource Description Framework (RDF), which is recommended by the W3C. RDF
is an object-oriented based standard, which provides reusable components for data
interchange over the web (Decker, Mitra, et al., 2000). It is unique in that every
concept represented in RDF has a universal unique identifier (the Uniform Resource
Identifier [URI]), which identifies every e-mail address, Web page, and other Web
elements. This ensures no semantic ambiguity. RDF also enables knowledge repre-
