Tutorial on Realizing a Semantic Web Application

tutorial at 11th International Conference on Business Information Systems (BIS 2008)

Innsbruck, Austria

RSWA 2008 - Realizing a Semantic Web Application

This turorial focuses on the step by step development of of a Semantic Web Application we named Music Event Explorer or shortly meex (try it out here http://swa.cefriel.it/meex). During this tutorial we challenge the Semantic Web technologies on the Web 2.0 ground of realising a mash-up that reuses, transforms and combines existing data taken from the open Web (namely MusicBrainz [1], MusicMoz [2] and EVDB [3]).

In the scope of this exercise we use:

OWL [4] to model the data sources

RDF [5] as unified relational data model

GRDDL [6] to translate XML data sources in RDF

D2RQ [7] to translate relational database in RDF

Jena [8] as application framework that support programmers in combining all the data in a unified RDF model and in managing it

a RDF storage (configured within Jena) to guarantee persistency of the unified RDF model

a OWL reasoner (configured within Jena) to reason upon the data in the unified RDF model

SPARQL [9] to query the unified RDF model

Exhibit [10] a Semantic Navigation Engine

The tutorial requires attendees to have some familiarity with the vision of the Semantic Web and with its technologies. A limited understanding of Java should be sufficient to follow the tutorial given that the tutorial will be mainly focused on the Semantic Web side of the problem of developing a Semantic Web application.
