"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."
