It's a dynamic world! Ubiquitous streams and the Linked Data Web

P
pooh42

This document summarizes the Linking Open Data (LOD) cloud, which contains over 200 open datasets with more than 25 billion facts interlinked by 400 million typed links that doubles every 10 months. It also describes semantic sensor network datasets and streaming query engines for continuous queries over linked data streams.
