Abstract (in Japanese) (See Japanese page) 
(in English) IPFS (InterPlanetary File System) is a distributed database middleware, and that is focused on as a Web3.0 key technology. In IPFS, each data is hashed according to its content and is retrieved by the exact match search by DHT. Furthermore, IPFS has a file versioning mechanism using ``Merkle DAG", where each hash value is linked in a DAG (Directed Acyclic Graph) structure. However, in the context that various information is exchanged and one or more attributes must be specified when a content lookup, e.g., in the IoT network, IPFS cannot be applied directly.
