2 What is Open Source Software source = software in source code form open = free to:» View the source code» Run the software for any purpose» Modify the software in any way» Distribute the software and any modifications Software development model Philosophy share and collaborate Licensing Model (3) The word free in free software pertains to freedom, not price Think of free as in free speech, not as in free wine (4) 2

3 Open Source Software Development Model Developers Form a development community Trusted Developers Deliver Source code Trusted Repository Bug reports & suggest patches Distribute Source code Distributors Users Users typically use software without paying licensing fees Users typically pay for training & support (competed) Users are responsible for paying/developing new improvements & any evaluations that they need (5) Open Source Licensing Models GNU General Public License BSD-style license Other models:» Mozilla» I.B.M., Apple, Intel, RealNetworks, etc.» Artistic license» GNU Lesser GPL Open Source Initiative (opensource.org) (6) 3

4 GNU & BSD-style Licenses GNU license Unlimited right to run program Unlimited access to source code Unlimited right to distribute verbatim copies May create derivatives IF you agree to make the derivatives free License is viral No warranties; disclaimer of consequential damages BSD-style license License grant: unlimited use, modification, distribution No warranties; disclaimer of consequential damages No endorsement Attribution (7) ARE THERE ONEM2M-BASED OPEN SOURCE IMPLEMENTATIONS? YES!! There exist three open source communities implementing onem2m specifications OCEAN (Korea), OM2M (Europe), IoTDM (USA) (8) 4

6 OPEN SOURCE iot.net/ocean (11) OCEAN Open Source Implementation What is OCEAN?» OCEAN (Open alliance for iot standard)» Established in Jan. 6th, 2015 by KETI and Korea government» Share IoT open sources based on IoT standards» Support vendors and developers using the OCEAN source code License policy» 3-Clause BSD Licence policy» Adopt IPR policy of the standards referred by OCEAN (in this case onem2m) Current Members» 214 members (Oct. 1st, 2015) Availability» onem2m-based IoT platform for device, gateway and server» Several guideline documents» Website: (12) 6

7 OCEAN Milestone Open source roadmap and release plan Mobius: Blue Octopus v1.1 for Spring Framework (Sep. 2015) Mobius: Yellow Turtle v1.1 for Node.js (Sep. 2015) &Cube: Lavender for Java v1.0 (Aug. 2015) onem2m - AllJoyn Interworking IPE (Feb expected) onem2m - OIC Interworking IPE (Feb expected) Semantic descriptor (Mid 2016 expected) OCEAN (Open alliance for iot standard) ~2015 onem2m 1.0 onem2m 2.0 Expand Interworking IEEE onem2m 2.0 IETF 2016~ Other Alliance (13) OCEAN open sources Opened Not yet opened SW name onem2m Nodes AE CSE ASN MN IN Framework Mobius Blue Octopus Spring Yellow Turtle Node.js Rosemary Java Node.js &Cube Lavender Java Node.js Thyme Java Node.js (14) 7

8 OPEN SOURCE Eclipse OM2M Open source standard based IoT platform eclipse.org/om2m (15) Eclipse OM2M Platform Open source project developed at the Eclipse Foundation. Horizontal service platform for M2M interoperability OM2M is under Eclipse Public License (EPL) a business-friendly free software license Compliant with SmartM2M (April 2014) Compliant with onem2m (September 2015) Restful API with generic set of service capabilities Facilitate deployment of vertical applications OSGI-based architecture extensible via plugins Developed by research labs and companies (16) 8

9 OM2M Building Blocks OM2M is a java platform running on top of an OSGi runtime Highly extensible via plugins. Flexible OSGi container: Equinox, Knopflerfish, or others. Flexible database: SQL or NoSQL. Each CSE includes required plugins and is build as an Eclipse product using Maven and Tycho. Generic Process Comm. Binding Content Format Storage Interworking Proxy Device Manage. Security Others. CORE HTTP COAP XML JSON H2 MongoDB Generic KNX HUE Phidgets LoRa SIGFOX ZIGBEE Z Wave EnOcean OMA DM LWM2M TLS TLS PSK Your plugin! Autonomic semantic OSGi framework (Equinox, knopflerfish, Karaf, etc.) Java Virtual Machine Operating System Hardware Opensource plugin LAAS CNRS private plugin LAAS CNRS private prototype plugin LAAS and partners plugin (17) OM2M Project Stats Website access Downloads : 1120 since April 2015 Contributors : 8 (18) 9

10 Eclipse OM2M Roadmap Eclipse OM2M Release (April 2015)» SmartM2M-based platform. Eclipse OM2M Release (September 2015)» onem2m-based platform.» IN, MN, ASN, and MN nodes support. Protocol-independent CORE module. HTTP and CoAP communication bindings. XML and JSON resource formats. Interworking driver for simulated devices. Web interface for resource browsing and debugging. DAO persistence layer for SQL and NOSQL databases. Semantic capabilities. Android support. (19) OPEN SOURCE IoTDM Daylight Open Source Project (20) 10

11 IoTDM from Open Daylight Project The IoTDM project is about developing a datacentric middleware onem2m compliant IoT Data Broker (IOTDM) Enable authorized applications to retrieve IoT data uploaded by any device. Project Creation Date: December 9th, 2014 Contributors: Cisco, ETRI, Echelon Repository: (21) IoTDM onem2m Features Implement IoTDM as closely to the onem2m specifications as possible. Keep in mind that the specifications are still evolving. RESTconf is also supported but it is a non-onem2m standard method for accessing the tree. Bundles providing the API: odliotdm-onem2m REST API commands include: onem2m-request-primitive for CRUDN Information about what is supported from onem2m R1 m.pdf Examples of CRUDN calls and JSON formats: (22) 11

12 ARE THESE OPEN SOURCE IMPLEMENTATIONS INTEROPERABLE? YES!! They have participated 1 st onem2m Interop. test event and shown their interoperability They have even created a forum, GoIoT Forum (23) 1 Introduction to open source 2 onem2m based open source implementations 3 Global IoT open source forum (GoIoT-Forum) 4 Reasons open source is good for onem2m 5 Summary (24) 12

13 Global Open Source IoT Forum - GoIoT Initiate a joint forum among onem2m based IoT open source communities» OCEAN (Korea)» OM2M (Europe)» IoTDM (USA) Founders: KETI, LAAS CNRS, Cisco, Sejong University Main purposes is to share experiences and information Expected activities:» Joint workshops and conferences» Joint hackathon events» Collaboration on open source implementations» Collaboration on standards activities» Global IoT research projects» Share activities, events, and news» Interoperability and conformance testing (25) Interoperability Make sure these three open source implementations are interoperable with each other» Participate onem2m Interoperability events» Closely testing each other» Open three live IN-CSE to public IoTDM (26) 13

14 Plug and Play Support plug and play» Developed core functions in one open source community can be plugged in to other open source implementations without modification (or with minimum modification)» App developers only need to develop an app only once in any platform Residential IoTDM Semantics (new function) (27) 1 Introduction to open source 2 onem2m based open source implementations 3 Global IoT open source forum (GoIoT-Forum) 4 Reasons open source is good for onem2m 5 Summary (28) 14

15 Legal Issues Founders of open source communities are all the member of onem2m, except for my university (Sejong University) All onem2m open source communities aware of the onem2m IPR policy Open source communities provide users the freedom to use their source code not Intellectual Property (IP) Policies of open source communities notify the fact that user has to follow the IPR policy of onem2m (29) Five Benefits of Open Source for onem2m 1. Try before you buy or implement 2. Freedom (use & modify) 3. Quality 4. Security & Reliability 5. Interoperability (30) 15

16 onem2m Eco-system with OSS GoIoT Forum Provide feedbacks for new standard features & Suggest new features from the open source communities IoTDM Adjust new standards features to open source implementations (31) 1 Introduction to open source 2 onem2m based open source implementations 3 Global IoT open source forum (GoIoT-Forum) 4 Reasons open source is good for onem2m 5 Summary (32) 16
