A layered architecture for the Semantic Web that adheres to software engineering principles and the fundamental aspects of layered architectures will assist in the development of Semantic Web specifications and applications. The most well-known versions of the layered architecture that exist within literature have been proposed by BernersLee. It is possible to indicate inconsistencies and discrepancies in the different versions of the architecture, leading to confusion, as well as conflicting proposals and adoptions by the Semantic Web community. A more recent version of a Semantic Web layered architecture, namely the CFL architecture, was proposed in 2007 by Gerber, van der Merwe and Barnard [23], which adheres to software engineering principles and addresses several of the concerns evident from previous versions of the architecture. In this paper we evaluate this recent architecture, both by scrutinising the shortcomings of previous architectures and evaluating the approach used for ...
