The new framework is built on the top of traditional World Wide Web technologies and provides the knowledge layer with the services of data interconnecting and transferring. Some current web technologies, including Unicode, URI and namespaces, form part of the

The knowledge layer is located between the networking layer and computing layer and provides the upper layer with machine readable knowledge representation services. This layer involves two kinds of knowledge: domain knowledge and non-domain knowledge. The latter can be described, retrieved, inferred and validated by the former. Unlike domain knowledge, non-domain knowledge can be maintained by collaborative efforts of domain experts and grass root users. XML-based RDF and OWL language is two most prevailing

The computing layer bridges the gap between the computing layer and the application layer and be responsible for knowledge retrieving, inferring, extracting and mining of the whole framework. Therefore, its knowledge processing technology depends on the two other layers. Some semantic web knowledge processing technologies, including RuleML,SPARQL and SPARQL-update , are used for knowledge computing in the computing layer because of

The application layer is the upper layer of the computing layer and provides the user layer with web2.0 application environments, such as Wiki, Blog, RSS and IM. The layer combines web2.0 with semantic web so that improves the effects of knowledge processing by manmachine collaboration. At the same time, the technologies of Application Programming Interface are usually required in this layer for keeping its independence with computing layer.
