Automotive to become data driven?
● Cars could become to transportation – What mobile phones became to oral communication (much more)
● What is car?– 4 wheels computer? a network of networks?
● An open development platform?– Non critical system to support services (IVI)
● No trade off in matter of security and safety
– Future proof APIs: stable models and operations● Longer life span than mobile (and related ecosystems, apps...)
– Seamless connectivity (local, offline, online, cloud etc)

Open connectivity foundation's missions
● Provide software linking the Internet Of Things– Focus on interoperability and seamless connectivity between devices
● Write specification, establish a protocol (formerly named OIC) – Rely on existing standards (IETF: CoAP, Cbor..)
● Sponsor reference implementation:– OpenSource (Apache 2.0 license) use existing FLOSS libs
● Hosted by Linux Foundation (like kernel, Tizen etc)
– Rule: No unimplemented features in specification
● Certify products for over 300 members (join us!)

OCF Automotive profile's mission
● Provide OCF technology for connected cars, by proposing:– A common definition of vehicle resources
– A common way to interact with those (inside or outside vehicle)
– Based on (or bridging to) existing standards
● Cooperative effort of existing FLOSS Automotive projects– Tizen, GENIVI, AGL, W3C, RVI ...

Open Automotive OSes & Relationships
● 2003: AUTOSAR AUTomotive Open System Architecture for ECUs (open to members)● 2009: GENIVI alliance created to standardize automotive
– OSS Supported by Car manufacturers, also members or AUTOSAR● 2019: Yocto project based on OpenEmbedded● 2012: Tizen:IVI is initiated by Intel from MeeGo (Nokia’s maemo + Moblin)
– GENIVI compliant, Rebased on Tizen:Common, Ported to Yocto Build system● 2014: Google announce Open Automotive Alliance (OAA) for Android● 2015: Automotive Grade Linux specifications published (Tizen:IVI fork)● 2016: AGL’s Unified Code base (Yocto+Tizen+GENIVI = UCB)● 2017: GENIVI announced partnership with Open Connectivity Foundation● 2017: IoTivity-1.3.0 supports Linux, Tizen, Yocto, GENIVI, AGL, Android and more

Getting started with IoTivity
● Download or rebuild C/C++ library from sources:– For most GNU/Linux, Tizen, Yocto and others OS
– Details: https://wiki.iotivity.org/build
● Note: Security mechanism is enabled at build time– For fast prototyping, rebuild without (unsecured)
● Get inspired by tutorial examples: Switch, Geolocation...– http://git.s-osg.org/iotivity-example/plain/README.md
● Try related projects: IoTivity-node, IoTivity-constrained

Prototyping use cases
Monitoring defective street lights:
– Sensor reads luminance
– Micro controller switches front lamp on (if too dark)
– GPS unit updates geolocation continuously
– Gateway sends message to cloud● To bridge to online services?:
– Ie: PSA REST API, OSM, Uber...
– Using IoTivity Web Service Interface (WSI)
