There is general consensus in literature that an architecture (at least) depicts the structure of a system within a specific context. This depicted structure should portray the components that a system comprises of, as well as the relationships between the identified components. One of the main purposes of a system architecture is the provision of an agreed-upon functional description of system structure, components and component interactions. It is thus plausible to state that an architecture for the Semantic Web is crucial to its eventual realisation and that it is therefore necessary to attach undisputable meaning to the specification of the architecture for the languages of the Semantic Web. The most well-known versions of the layered architecture that exist within literature have been proposed by Berners-Lee, and the literature offers no description or specification of meaning for any of these. Furthermore, 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. In addition, none of the current formal initiatives by the W3C address the Semantic Web architecture specifically, which could be regarded as an omission. 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.

A more recent version of a Semantic Web layered architecture, namely the CFL architecture, was proposed by Gerber, van der Merwe and Barnard [1].
