Scheduling use case

"Jack is trying to coordinate a meeting with his friends Robin, David 
and Kate. They each live in separate cities but often bump into each 
other at different conferences throughout the year. Jack wants to find a 
time when all of his friends are in the same city. Robin publishes her 
schedule on her home page using the hCalendar microformat. David 
publishes his in Embedded RDF using some RDF calendar properties and 
Kate uses a blog engine that encodes her diary as RDFa. Jack uses an 
online calendaring service that publishes an RSS 1.0 feed of his 
schedule. Jack writes a Sparql query that includes the three web pages 
and his own RSS feed in the FROM clause. The query looks for dates when 
all four friends are in the same city. Jack runs this query using his 
GRDDL-aware Sparql engine that fetches each web page and uses GRDDL to 
extract triples from each one, combining them into a single model 
against which the query is evaluated. Jack is delighted to find that all 
four of them will be at conferences in LA at the beginning of September 
and he immediately starts looking for restaurants to book for their 
night out."
