Semantics for the Rest of Us -- Variants of Semantic Web Languages in the Real World
Held in conjunction with 8th International Semantic Web Conference (ISWC 2009)
ObjectivesThe Semantic Web is a broad vision of the future of personal computing, emphasizing the use of sophisticated knowledge representation as the basis for end-user applications' data modeling and management needs. Key to the pervasive adoption of Semantic Web technologies is a good set of fundamental "building blocks" - the most important of these are representation languages themselves. W3C's standard languages for the Semantic Web, RDF and OWL, have been around for several years; instead of strict standards compliance, we see "variants" of these languages emerge in applications, often tailored to a particular application's needs. These variants are often either subsets of OWL or supersets of RDF, typically with fragments OWL added. Extensions based on rules, such as SWRL and N3 logic, have been developed as well as enhancements to the SPARQL query language and protocol (http://esw.w3.org/topic/SPARQL/Extensions).
In this workshop we will explore the landscape of RDF, OWL and SPARQL variants, specifically from the standpoint of "real-world semantics". Are there commonalities in these variants that might suggest new standards or new versions of the existing standards? We hope to identify common requirements of applications consuming Semantic Web data and understand the pros and cons of a strictly formal approach to modeling data versus a "scruffier" approach where semantics are based on application requirements and implementation restrictions.
The workshop will encourage active audience participation and discussion and will include a keynote speaker as well as a panel.
