REST is a software architecture style, and it provides a simple, scalable, high-performance guideline in the complex network service environment. There are many famous web services with the REST design philosophy, such as Amazon AWS, Facebook, Yahoo, and Google Web Service and so on. Web service’s resources are identified and linked through URI (Uniform Resource Identifier). Therefore, the integrity of data on the server and the resource load balancing becomes very important. In this paper, we apply P2P technology to access the resources on the server, with RDF (Resource Description Framework) as a reference and the triple stored though the hash function’s result. Each triple is divided into subject, predicate, and object to be stored in three different nodes. In addition, with respect to query operations, this paper proposes a bidirectional query mode, in which the query response will be faster when peer receive requests. We apply P2P technology to access the resources on the server have two benefits: (1) in the traditional mode, resource access will miss when the server failure. But in P2P architecture, the single node failure can be recovered through other nodes in order to achieve high availability. (2) P2P is using hash function to achieve load balance.
