Abstract-The approach of Internet of Everything brings some challenges to the storage and processing of those connected data. Aiming at problems of complex construction process, tedious maintenance of relational table and weak expansibility of table structure when using traditional relational database to store the data, we propose an information management method based on RDF data model and ontology technology. Firstly, the data model used in this method can simplify modeling and operating of the data, it also has flexible ability for property expansion. Secondly, combined with ontology reasoning technology, this method ensures the consistency of information model, and provides implicit meaning of data for information service.
