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

(4)

The word “free” in “free software” pertains to freedom, not price

Think of “free” as in “free speech,” not as in “free wine”

Bug reports & suggest patches

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

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: http://iotocean.org

Autonomic

• 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.

IoTDM from Open Daylight Project

The IoTDM project is about developing a data-centric 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: https://git.opendaylight.org/gerrit/iotdm

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: odl-iotdm-onem2m

REST API commands include: onem2m-request-primitive for CRUDN

Information about what is supported from oneM2M R1 https://wiki.opendaylight.org/images/5/55/IoTDM_oneM2M_Features_Lithium.pdf

ARE THESE OPEN SOURCE IMPLEMENTATIONS INTEROPERABLE?

YES!!

They have participated 1st oneM2M Interop. test event and shown their interoperability

They have even created a forum, GoIoT Forum

Founders of open source communities are all the member of oneM2M, except for my university (SejongUniversity)

All oneM2M open source communities aware of the oneM2M IPR policy

Open source communities provide users the freedomto 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 ”

Legal Issues

(30)

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
