This is a virtual Meetup occurring at 8AM Pacific time (11am Eastern, 5pm Central European Time). For help with your timezone calculation, refer to this (

The meetup will be held on Google Hangouts and you will be able to watch the live stream directly on YouTube.

This talk will present the OGC® SensorThings API specification and its MQTT extension, a new OGC® standard for IoT data interoperability that simplifies and accelerates the development of Internet of Things (IoT) applications.

The IoT marketplace is a rapidly growing space with companies developing their own version and interpretation of an IoT platform. Unfortunately many IoT silos have emerged. There is a growing need to have a standards-based solution to truly realize the vision of having a connected world where sensors from across different disciplines can utilize a single API and provide enriched metadata to form a system of systems.

We will present and demonstrate the OGC® SensorThings API. SensorThings API is semantically rich (based on the OGC/ISO Observation and Measurement), very easy to use (RESTful and JSON), built for real-time applications (MQTT extension) and it allows for simple modeling of the observations, the physical world and the sensors used to observe and measure real phenomena in it. The demonstration will also showcase the OGC® SensorThings API MQTT extension based on Eclipse Paho and Mosquitto.

Speaker: Steve Liang

Steve Liang is a researcher, teacher and entrepreneur. Steve is currently an associate professor at the University of Calgary in Canada. From 2011~2014, Steve held the AITF-Microsoft Industry Research Chair on the Open Sensor Web. Steve is also the founder and CEO of SensorUp ( (

Steve’s goal is to disrupt the silos of the Internet of Things and to empower anyone to build interoperable connected applications effortlessly. For example, Steve is currently the Standard Working Group Chair of the Open Geospatial Consortium SensorThings API and the Rapporteurs of the ITU-T’s Study Group 11/Q12 on the Internet of Things test specifications. The result of both standard works is to provide a uniform way to expose the full potential of the Internet of Things.

Steve received his bachelor degree in Surveying Engineering from Taiwan (NCKU, 1999) and Ph.D. degree in Geographical Information Systems from Canada (York University, 2007). During his Ph.D. study, he also contributed to the development of one of the first virtual globe systems in the world, called GlobeView. GlobeView was later commercialized by GeoTango Corp., and subsequently acquired by Microsoft in 2005.
