Richard Wallis has followed up his recent announcement that WorldCat data can now be downloaded as RDF triples with an explanation of how to put that data into a triple store. He begins: “Step 1: Choose a triplestore.  I followed my own advise and chose 4Store.  The main reasons for this choice were that it is open source yet comes from an environment where it was the base platform for a successful commercial business, so it should work.  Also in my years rattling around the semantic web world, 4Store has always been one of those tools that seemed to be on everyone’s recommendation list.”

He goes on, “Looking at some of the blurb – 4store is optimised to run on shared–nothing clusters of up to 32 nodes, linked with gigabit Ethernet – at times holding and running queries over databases of 15GT, supporting a Web application used by thousands of people – you may think it might be a bit of overkill for a tool to play with at home, but hay if it works does that matter!”

Next up, “Step 2: Operating system.  Unsurprisingly for a server product, 4Store was developed to run on Unix-like systems.  I had three options.  I could resurrect that old Linux loaded pc in the corner, fire up an Amazon Web Service image with 4Store built in (such as the one built for the Billion Triple Challenge), or I could use the application download for my Mac.”
