Slide 3

Motivation for ONS (1)

Most medical devices in US should include an unique device

identifier (UDI) ..


Slide 4


Company?

Model No?

Googling?

Contact?

Current situation ..

I want to find

instruction sheets for

my medical devices.


Slide 5


I can get information

of medical devices

using reader !!

If a reader reads ID tags attached to medical devices ..

But, I cannot

understand what

does it mean .. An ID tag

cannot contain

large data ..

01010011

00010101

01010010


Slide 6


Is there any service to

find where the instruction

sheets for medical

devices are?

So, how can I find the instruction sheets for medical devices?

That is

Object Name Service

(ONS)

Object Name Service (ONS)

– Service to lookup static information about the given GS1 Identification keys using the

Internet’s existing Domain Name System (DNS) protocol

ONS lookup for static

information of things

(e.g., product info

Extract the desired GS1 ID Key type and GS1 ID Key from the sequence of data

– (00)306141417782246356(02)50614141322607(37)20

Type: GTIN (02)

Key: 50614141322607

AUS format

– language code | country code | type | key

AUS conversion example

– GDTI 0614141665815 with serial 999888777, English service in Canada

AUS: en|ca|gdti|0614141665815

Slide 14

Nameserver (NS) delegation

– Desired name servers exists below current ONS Peer Root

Delegation name (DNAME) delegation

– Desired name servers exists in another ONS Peer Root, not current ONS Peer Root

– Using the GS1 prefix (last three digits), identify where the query is destined.

Motivation for Discovery Service (1)

Object Name Service

(ONS)

Is ONS enough to

find dynamic

information for my

things?

Retailer

I found faults for all

same typed

products

I don’t know!

Give me list of

EPCISs related

to given GS1 ID?

• Discovery Service (DS)

– The service to lookup dynamic information about the given GS1

Identification keys and provide dynamic information to DS client

Discovery Service in Oliot

DS lookup for dynamic

information of each

individual thing (e.g.,

historic locations of

things)

Slide 26

Current DS is tailored to a supply chain in B2B application

– B2C should be considered in IoT.

How to satisfy client’s demand using DS?

– Client may want to know the real locations of the stores selling the desired

products near his current location

Discovery Service from an aspect of B2C

Client

I want to buy more.

Where can I buy them?
