An RDF-Based Annotation Framework for Providing Web Resources Integrity

Data integrity of Web resources is becoming more and more important with the increasing development of Internet. In the context of active intermediaries, current solution for data integrity such as inline method can´t provide integrity protection for Web resource without text-based content structure (e.g. HTML forms). In addition, the current solution can´t help the server to validate the integrity of Web resource, which is required in some Internet application fields. Thus, in this paper we propose a RDF-based annotation framework as a general-purpose approach to provide data integrity for Web resources. The annotation framework can support any kinds of Web resource using a single RDF-based annotation file to describe the integrity related information, and it stores the annotation files in the specialized annotation server so that both the client and the server can validate data integrity. The framework operation, protocol extension, delivery mechanism and language support are covered in this paper. As an option of the annotation framework, we also present a RDF-based Web resource description method to solve the limitation of the annotation file naming rule in annotation framework
