TripletDS: a prototype of dataspace system based on triple data model

A dataspace system provides a powerful mechanism for searching and querying the structured, semi-structured, and unstructured data in an integrated manner. This paper aims to build a prototype called as triplet dataspace system (TripletDS) to provide an on-demand large scale data integration solution with less effort. The TripletDS is a prototype of dataspace system based on triple model. The triple model is a simple and flexible data model which supports the subject-predicate-object (SPO) query language. The proposed prototype has the ability to efficiently bridge the gaps between syntactic and structural heterogeneity among data. The performance of TripletDS has been verified on the datasets including personal data and relational data.
