Resumen
— In the last decades, object-oriented approach was
able to take a large share of databases market aiming to design
and implement structured and reusable software through the
composition of independent elements in order to have programs
with a high performance. On the other hand, the mass of
information stored in the web is increasing day after day with
a vertiginous speed, exposing the currently web faced with the
problem of creating a bridge so as to facilitate access to data
between different applications and systems as well as to look
for relevant and exact information wished by users. In addition,
all existing approach of rewriting object oriented languages to
SPARQL language rely on models transformation process to
guarantee this mapping. All the previous raisons has prompted us
to write this paper in order to bridge an important gap between
these two heterogeneous worlds (object oriented and semantic web
world) by proposing the first provably semantics preserving OQLto-SPARQL translation algorithm for each element of OQL Query
(SELECT clause, FROM clause, FILTER constraint, implicit/
explicit join and union/intersection SELECT queries).
