1. Applying SAREF to oneM2M Proposal for discussion in MAS – DRAFT From: Omar Elloumi (ALU) Source: Alcatel-Lucent (ATIS) Meeting Date: 2015-03-23 Agenda Item:

2. © 2015 oneM2MMARCOM Report oneM2M Release 1 did not support semantic interoperability: it is assumed that AE (application entities) that produce/consume data have a prior common understanding of the data that is being exchanged oneM2M Release 2 will support semantic interoperability TR-0007 provides initial study on how to make oneM2M system semantic enabled. Objective of the slide: what normative work needs to take place in the context of oneM2M Release 2: Impact on resource structure Impact on procedures and message flows (discovery) Impact on SCF or functions Methodology: let’s take a concrete ontology as a basis: SAREF Introduction
