It’s also worth noting that linked data is an API (a set of best practices for publishing data on the Web), whereas RDF doesn’t assume the Web. They aren’t the same thing.
For example, you can load RDF into Apache Spark/GraphX (useful structures) and then hammer it offline with useful operations on an cluster.
