USE THE internet as a database. Across the internet, some generous providers make their data available not only as RDF/OWL, but via a SPARQL endpoint that you can send queries to. It's like an API, but instead of getting a response with all the data the developer thought you might like, you get the results of the query you want. It's even possible to query across multiple endpoints in a single query. SPARQL is similar enough to SQL to be easy to learn. In this post, we start out looking at SELECT queries against DBpedia.
