Open Platform for IoT-Aggregator
Open Device Platform
▪ Devices from different manufacturers/vendors can
communicate with each other using IoT-Aggregator
▪ Devices are managed using ubiquitous ID
infrastructure
Open Application Platform
▪ Applications developed by application vendors or
individuals can be distributed, as well as official
applications provided by manufacturers
▪ Can be considered an “application store” for IoT, like
those for smartphones
Virtual devices
▪ Virtual devices are enhancing real devices can be
created
▪ Can be used just like real devices, but with access
control and other additional functions provided in the
cloud

General API Specification of ucR-Light
1. Retrieving data for each sensor
/api/<ucode>/sensorstate/
% curl
http://133.11.240.193/api/00001C00000000000002000000
063433/sensorstate/
• Retrieving temperature sensor data of ucode =

OPaaS.io: Omotenashi Platform
Overview
▪ OPaaS.io: “Omotenashi “Cloud” is a general-
purpose Personal Data Store (PDS) that uses the
IoT technology.
Functions
▪ Authorization: Starting authentication, logging in
by IDM, and acquiring an access token.
▪ User Management: Searching users, creating
users, and updating users’ information.
▪ Access Authority Management: Searching
authorized services, searching authorized user
attributes, and updating authority.
Enhancement
▪ Functions and APIs are enhanced in this project
New Enhanced OPaaS.io is published at:
▪ https://contest.opaas.io/api-spec.html
“Omotenashi” cloud dashboard
(user interface of PDS)

u2 Open Data Catalog (1)
Overview
▪ u2 Open Data Catalog is a open data catalog component in u2
architecture.
▪ It can contain not only metadata (catalog data) of open data but
also data bodies.
▪ It can deal with not only static data but also real-time dynamic
data.
Function
▪ Search data: searching ucR triple data from a certain ucode
▪ Resister data: registering ucR triple data associate with a certain
ucode
▪ Get data from ucode: getting ucR triple data from a certain
ucode
▪ Get data from property parameters: getting ucR triple data by
property-based query
▪ Update data from ucode: updating ucR triple data from a certain
ucode
▪ Update data from property parameters: updating ucR triple data
by property-based query
▪ Delete data: deleting ucR triple data from a certain ucode
▪ Delete data property: deleting ucR triple data by property-based
query

u2 Open Data Catalog (2)
New component
▪ Blockchain-based new open data
catalog system.
▪ Sapporo city and Fukuoka city are
now trying to use the new system.
▪ Blockchain-based open data
catalog is useful when community-
based organizations are managing
open data storage such as NGOs
and civic tech organization.

kokosil
Overview
▪ kokosil is a software package to provide
information for visitors and tourists in towns,
tourist spots, commercial facilities, museums, parks,
exhibition venues, etc.
▪ It has a management function to register
information on target areas, tourist facilities, stores,
etc. easily, information distribution function to
provide timely information on popular seasonal
spots, ongoing events, etc.,
▪ kokosil has been introduced in more than 50 areas
and facilities so far.
▪
Enhancement
▪ Kokosil and Omotenashi cloud are integrated for
high-quality personalized end-user services
▪ Tourism information is customized according to
the personal data in OPaaS.io: preference, physical
condition, language, ...

IoT Engine (μT-Kernel 2.0)
Overview
▪ IoT-Engine is a standard development platform,
standardized by TRON Forum, for Open IoT to
realize "Aggregate Computing".
▪ IoT-Engine standard specifies the connector on
the Micro Processor Unit (MPU) board, and the
RTOS used by the MPU, and requires the function
to connect to the cloud services on the Internet.
▪ The RTOS used on the IoT-Engine is µT-Kernel 2.0
which TRON Forum releases as open source.
Enhancement
▪ µT-Kernel 2.0 (IEEE Std 2050-2018) is a light-weight
real-time operating system with small footprint,
which is open source software and adequate for
the IoT edge node devices.
▪ Standard edge nodes of the u2-based architecture
uses µT-Kernel 2.0.

Orchestrating your own
smart city app/platform
out of the box
u2 Toolbox
Already validated with 3 use cases in CPaaS.io
(Sapporo Open Data for Tourism, Tokyo Public
Transportation Open Data, Yokosuka Emergency
Medical Services)
Additional 3 use cases in CPaaS.io
(Kochi IoT Fishery, Kochi IoT Forestry,
e-MCDH: Mother-Child-Doctor Handbook)

Conclusion
• 5 new components have been introduced to CPaaS.io platform
• 3 components have been enhanced.
• Pre-existing components have been integrated and validated
• New standard IEEE 2050-2018: IEEE Standard for a Real-Time Operating
System (RTOS) for Small-Scale Embedded Systems (μT-Kernel 2.0)
Outlook beyond the project
Edge node components of u2 toolbox such as IoT-Engine, μT-Kernel, and ucode BLE are
available from the market or open source software of TRON Forum (www.tron.org). Cloud-
side components are available as web service and/or API-services such as “Omotenashi”-
cloud, u2 Open Data Catalog, and kokosil. TRON forum and open data/IoT community of
smart cities such as Yokosuka, Sapporo, and Tokyo are strongly support our architecture and
building a ecosystem of u2 toolbox.
