Decentralization of publication is one of the great advantages of the Web's infrastructure. However, until now, Web failed to fully engage the user to contribute and add contents. This is the primary motivation for Web 2.0, which revolves around the notion that people can add contents for Collective Intelligence. Enterprises can also use Web 2.0 to reduce costs and increase profits through Social Network Analysis. Web 2.0 applications target to interconnect the users and contents so that the users can use contents to find participants and vice versa. Therefore, if the users are further assisted, to add contents to the web, link people with people, and link people with contents; then the distinction between the physical and electronic worlds will cease to exist. This web environment will enable the users to use web for Collective Intelligence and Social Network Analysis, defined here as 'Internet Singularity'. This paper proposes an application architecture based on decentralized information structure that links contents and people together. The architecture embraces FOAF, Atom, RDF, RDFS and OTER (Online Trust Evaluation RDF). OTER is constructed by using RDF Schema for linking and representing online trust evaluation information within Web 2.0. This architecture can be used as a model to develop Web 2.0 applications for any e-domain. However, it is believed that trust will be the main synthetic force in Web 2.0 as it is in the current physical environment. The proposed application architecture targets to assist the participants in committing online transactions while contributing towards Collective Intelligence.
