Abstract:
The Semantic Web has been developed in order
to publish and access a lot of information for
automatically processing of data and information by
machines rather than for people. RDF (Resource
Description Framework) data model is a proven
technology for generating semantic data from existing
relational data representation. The certain loss of
semantics has occurred in the generation of relational
data to RDF. This paper describes the development of
the RDB to RDF mapping system, which transforms
relational data into semantically structured data and
publishes it on the web. The proposed mapping solution
extracts relational schema and data from an existing
relational database. Then, relation URI, attribute URI
and tuple URI are generated. Finally, a series of triples
are generated from those URI and validated against
RDF validator. The implementation of the tool is made
using the standard relational databases such as sakila,
world and employee datasets.
