*The SenML specification becomes a standards track RFC

A new standards track RFC (RFC 8428) was published in August 2018. The RFC, which specifies Sensor Measurement Lists (SenML), is currently a Proposed Standard. Take a look at the document’s history at https://datatracker.ietf.org/doc/rfc8428/.

SenML is a notation for sensor measurements (values) and associated metadata. The metadata may include the id of the sensor, a unit, a timestamp, or the sensor’s location. Shortcuts for reporting multiple measurements from a single sensor, or measurements from multiple related sensors are defined. A number of representations for the measurements and metadata are allowed, including familiar JSON and less known CBOR (Concise Binary Object Representation). SenML-formatted data may be transferred with an application-layer protocol like CoAP or HTTP. A paper presented at the IAB-organized IoT Semantic Interoperability Workshop (held in 2016) described SenML as a “simple building block for IoT semantic interoperability.”

You can learn about SenML, if you take our course OBIR.

Micromole tested in Berlin sewage network

The prototype of the IoT­-based system Micromole (a result of our project microMole, see micromole.eu for more information) for aiding in the identification of strongly toxic waste disposals in the sewage was successfully tested by the Federal Criminal Police Office of Germany (Bundeskriminalamt) and the Central Forensic Laboratory of the Police (Centralne Laboratorium Kryminalistyczne Policji) of Poland during the 3rd and the 5th of December 2018.

The system was able to detect and collect waste of 9 controlled waste spills in the sewage network.

Our new project: FLEXNET


We started work on a new Celtic-Plus project, called FLEXNET. WUT and two other Polish partners (Orange and Blue Technologies) joined forces with partners from Spain, Turkey, France, Belgium, Canada, and South Korea. The international Consortium aims to develop a “flexible IoT network.” The effort combines the areas of the Internet of Things, software-defined networking, and 5G. Read more here.

*FIWARE Context Broker becomes a Connecting Europe Facility (CEF) Building Block

The FIWARE Context Broker, a reusable context-handling component, has been adopted by CEF (Connecting Europe Facility) as a so-called building block: https://www.fiware.org/2018/08/08/fiware-context-broker-launches-as-a-cef-building-block/.

The Context Broker makes it possible to store and access context-information using simple context models. It offers a RESTful API and supports subscriptions and notifications.  Learn more here.

Notably, we offer a FIWARE Context Broker-based lab exercise in our course AKIR (Context-Aware IoT Applications).  The objective is to teach students about FIWARE context modeling and introduce them to Orion Context Broker. The exercise was developed at ZSUT by Szymon Caban, as his BS thesis.
