Semantic content repository based open source digital library storage service implementation

A storage service implementation, based on a semantic content repository of Tupelo is designed and developed. The architecture of the implementation makes it possible to accommodate both bitstream and metadata storage. The mapping solution from the digital library entities and their relations to the counterparts with semantic data structure is also provided. A case study on an open source digital library shows that this method is practicable and applicable for semantic data storage in digital library.
