Transformation of DSpace Database into Ontology.
Lecture Notes in Computer Science(2014)
摘要
Ontologies enable controlled sharing and exchange of information among autonomous data sources. DSpace is an open source software for institutional repositories. It employs a traditional database to store the metadata that provides detailed description about digital documents. We need to transform the DSpace database into an ontology in order to share and reuse its information. However, the existing transformation systems are not able to transform the DSpace database accurately into an ontology because its schema is meta-schema. The proposed system first creates a normalized relational database for the data model of an institute from DSpace database and then transforms it into an ontology. The system has been implemented and its results demonstrate that transformation is correct.
