We study the problem of answering queries through a
RDF/RDFS ontology, given a set of view-based mappings
between one or more relational schemas and this target ontology.
Particularly, we consider a set of RDFS semantic
constraints such as rdfs:subClassof, rdfs:subPropertyof,
rdfs:domain, and rdfs:range, which are present in RDF
model but neither XML nor relational models. We formally
define the query semantics in such an integration scenario,
and design a novel query rewriting algorithm to implement
the semantics. On our approach, we highlight the important
role played by RDF Blank Node in representing incomplete
semantics of relational data. A set of semantic tools supporting
relational data integration by RDF are also introduced.
The approach have been used to integrate 70 relational
databases at China Academy of Traditional Chinese
Medicine.
