An oft-repeated concern in discussing large-scale deployment of Semantic Web ideas is that of 'scale.' With many of the better known data stores upon which the Semantic Web depends capable of storing only tens or at best a few hundreds of millions of RDF triples, it can be difficult to argue that the technology is fit for real-world deployment at scale.
There are, of course, different ways of managing data, and it's not always necessary to store everything in one massive store... but for those concerned about scale today's news from UK-based Garlik may well put their minds at rest.
The company has taken their internally developed (and massively scalable) RDF triple store and released it to the world under an Open Source license as 4store.
I spoke with the company's CEO and Head of Architecture just ahead of the launch, to learn more about the system and their motivation behind sharing it.
