The Internet of Things(IoT) with billions of connected de- vices has been generating enormous amount data of data every hour. Connecting every data item generated by IoT to the rest of the digital world to turn this data into meaningful actions will create new capabilities, richer experiences, and unprecedented economic opportunity for businesses, individuals, and countries. However, providing an integrated view for exploring and querying such data at real-time is extremely challenging due to its Big Data natures: big volume, fast real-time update and messy data sources. To address this challenge we provides a unified integrated and live view for heterogeneous IoT data sources using Linked Data, , called the Graph Of Things(GoT). GoT is backed by a scalable and elastic software stack to deal with billion records of historical and static data sets in conjunction with millions of triples being fetched and enriched to connect GoT per hour at realtime. GoT makes hundreds of thousand of IoT stream data sources available as a SPARQL endpoint and continuous query channel via the web socket protocol that enables us to create a live explorer of GoT at http://graphofthings.org/ with just HTML and Javascript.
