At its recent member meeting the IPSO Alliance formally appointed Universal Devices’ (UDI’s) Michel Kohanim as co-chair of the Semantic Working Group, alongside Milan Milenkovic of IoT Sense. IPSO also announced that UDI recently increased its membership level to Promoter, as a result of its belief in the vision and direction of IPSO Alliance.

Under Michel and Milan’s guidance, the Semantic Working Group will focus on accomplishing interoperability across different information models developed by IPSO and other organizations. It will attempt to do so by developing and promoting a “meta” information model that represents key inherent properties, methods, and relationships of physical and virtual entities that are being modeled.

The group will perform this work in three mostly consecutive phases:

  1. Definition of architectural principles and design guidelines for constructing interoperable semantic data models
  2. Definition of meta-model for describing semantic properties for interoperability
  3. Mapping of meta-model to specific bindings, such as LWM2M (IPSO gen 1) and OIC

The current Semantic Working Group efforts build on IPSO’s initial Smart Objects work that was focused on developing the Starter and the Expansion Packs to allow developers to re-use object definitions throughout various applications running on Internet of Things devices but also on the server-side infrastructure. The Starter Pack contains 18 Smart Objects and the Expansion Pack has 16 common template sensors, 6 special template sensors, 5 actuators and 6 control switch types.

Michel joins a list of IPSO Alliance committee chairs that includes Protocol Committee Chair Tim Spets of Greenwave Systems, and Security, Identity and Privacy Working Group Chair Ned Smith of Intel.
