PlanetData partner, Freie Universität Berlin (FUB), Germany, together with the LATC FP7 partner, delivered a tutorial entitled "Practical Cross-Dataset Queries on the Web of Data". The tutorial was delivered during the 22nd International World Wide Web Conference (WWW2012) event in Lyon, France on the 17th of April 2012.

The web is increasingly developing into a platform for data exchange, as shown by the rise of web APIs, HTML's Microdata, by Google, Microsoft and Yahoo!, Facebook's Open Graph Protocol, the Linked Open Data Cloud, etc. - all these sources of web data have one thing in common: they can be converted to the RDF data model with off-the-shelf tools, or already use RDF.

The SPARQL query language is W3C's recommended standard for querying RDF. Recently updated to a much-expanded version 1.1, SPARQL provides many features that are geared towards queries across several sources of data. This makes RDF+SPARQL a powerful “lingua franca” for web data, allowing data mashups and ad-hoc queries across multiple heterogeneous data sources at a higher level of abstraction than the ubiquitous JavaScript mashups. The topic of the tutorial is how to put this into practice.
