This workplan correspond to a Summer Semester Research program where
students choose a topic and they should investigate on it. It is composed
of 8 milestones where they have to learn about the state of the art in
the topic selected achieving some goals and they have to present a final
work at the end.
This topic consists on the development of a wrapper between two of the
most current important languages being used in Semantic Web. The wrapper
will have to translate between QEL (query based on the logical language
datalog and used for querying in the Edutella Peer-to-Peer
network) and RQL (standard language to query RDF repositories). In this
network a query in QEL will be send to all the peers. This wrapper will
allow that peers that only understand RQL could join the network. The
wrapper will translate the query from the network (in QEL) into RQL and
forward the translated query to the provider. Then the provider will
answer the query and send this answer to the wrapper. The wrapper will
translate again the query (this time from RQL to QEL) and resend the
answer to the network.
