The present invention relates to a system for storing and retrieving resource description framework (RDF) triple data based according to RDF triple data types, which may differently store and retrieve RDF triple data according to RDF triple data types. The system comprises: a data repository including a plurality of triple repositories storing and retrieving data in a triple form, a document search engine storing and retrieving text documents, and a key value repository storing data by key values; a type sorter sorting receiving triple data, and sorting into space-time triple, text triple, and general triple; and a triple distributor distributing triple data sorted as the space-time triple to the key value repository, distributing triple data sorted as the text triple to the document search engine, and data sorted as the general triple to the triple repositories. The system as described above may store R space-time data additionally to the key value repository and may retrieve the R space-time data (divide and process space-time queries), thereby reducing a space-time query processing time as compared to technology of only using conventional triple repositories. |
