OneM2M Tutorials using Jupyter Notebooks

oneM2M provides a series of introductional hands-on tutorials to various oneM2M concepts, resource types and requests.

This page provides an overview, links, and introduction and overview to these tutorials.

Episodes

Episode 0 - Introductions

In this first episode Andreas and Ken introduce a series of short talks on using oneM2M standards to build open and interoperable IoT systems. This talk begins with an introduction to the basic elements in an IoT system and where oneM2M fits into the picture. In future talks, Andreas will illustrate oneM2M’s capabilities via a set of Jupyter Notebooks that contain software and explanatory notes.

Episode 1 - Setup Configurations

This series of talks uses Jupyter Notebooks to illustrate the basic capabilities that oneM2M standards support. In this talk, Andreas explains how to access the Notebooks online, and how to run a oneM2M Common Services Entity (CSE), which functions as an IoT platform, inside the Notebooks. He also explains how oneM2M supports the exchange of messages between applications and a CSE.

Episode 2 - First Contact with oneM2M

In this episode Andreas and Ken take a more detailed look at oneM2M requests. The practical part involves a request to the oneM2M CSE to retrieve information about its “resource tree”. The resource tree corresponds to a “digital twin” of an IoT system.

Episode 3 - Basic Resources & Requests using REST Calls

In this episode Andreas and Ken explore how IoT resources are organized in the oneM2M resource tree. The practical part uses some of oneM2M’s most basic resource types and we learn how an application can create new resources in the CSE allowing another application to retrieve information about those resources.

Episode 4 - Resource Discovery

An essential function in all IoT systems is to find and discover stored resources. In this episode Andreas and Ken talk about the “Discovery” function and how it is implemented in oneM2M.

Episode 5 - Groups

The "Group Management" Common Service Function (CSF) of oneM2M provides a way to organize multiple IoT resources into collections for efficiency and ease of management. Example scenarios might involve grouping street lights along north and south bound sections of a highway, for environmental sensors in adjoining city districts or, to electrical outlets on different floors in an office building. oneM2M's Group Management CSF helps users to manage IoT devices in groups in addition to the possibility of issuing commands to individual items. In this episode Andreas and Ken talk about the this functionality and how it operates in oneM2M.

About oneM2M

oneM2M is the global standards initiative that covers requirements, architecture, API specifications, security solutions and interoperability for Machine-to-Machine and IoT technologies. oneM2M was formed in 2012 and consists of eight of the world's preeminent standards development organizations: ARIB (Japan), ATIS (U.S.), CCSA (China), ETSI (Europe), TIA (U.S.), TSDSI (India), TTA (Korea), and TTC (Japan), together with industry fora and consortia (GlobalPlatform) and over 200 member organizations. oneM2M specifications provide a framework to support applications and services such as the smart grid, connected car, home automation, public safety, and health. oneM2M actively encourages industry associations and forums with specific application requirements to participate in oneM2M, in order to ensure that the solutions developed support their specific needs.
