oneM2M – The StandardService layer for things and platforms

A global standard for a software “framework” - enabling an IoT ecosystem - focus on interoperability, avoid vendor lock-in Located between the IoT applications and communication HW/SW that provide connectivityProvides functions that IoT applications across different industry segments commonly needLike an “Android” for the Internet of ThingsIt sits both on the “things” and on the infrastructure

Interoperability of Data is keyData Modeling• The goal: Modularity – Flexibility – Abstraction

• To ease the development of applications on top of the oneM2M layer• Rich set of abstract data models for home domain and interoperability

with other technologies • oneM2M Home Appliance Information Model (HAIM) based on Smart Device

Template (SDT) 3.084 ModuleClasses and 50 DeviceModels for home domain

• Fully interwork-able with OCF and OMA GotAPI data models• Ontology mapping from SDT 3.0 to oneM2M Base Ontology

• Work in progress: TS-0023 - from HAIM to SDT based Information Model and Mapping for Vertical Industries

• SDT4.0 will provide more powerful modeling capabilitiese.g. data types, device inheritance, semantic references, product definition

Interoperability of Data is keySemantic Interoperability• Value-added features related to the meaning of data and resources based

on semantic descriptions to control, validate, understand & orchestrate the data

• Supporting semantic query, semantic mashup, ontology management, semantic validation, access control

• oneM2M Base ontology aligned with ETSI SAREF ontology• Ontology based interworking enables automated interworking through

ontology mapping

Semantic Mashup a process to discover and collect data from more than one source, and conduct semantic data orchestration (integration/ computation) on behalf of anapplication.

• oneM2M based CloudAPI forConsumer IoT & Smart Home

• Hides from the app developer the complexities involved with interacting with a diverse set of IoT devices

• Time to adapt Applications < 2 days

SCOPE: Features supported over the Mca reference point (IN-AE IN-CSE)

oneM2M enables horizontal Smart Data Usage

• Device- and cloud independent application development

• Abstraction - hide complexity from the App Developer

• Semantic interoperability

• Interworking with domain specific technologies

• Global open standard => vendor agnostic implementations
