 July 7 2014 – oliot 1.0
(latest implementation of
EPCglobal framework,
run on any cloud and
supporting mysql and
cassandra)
 4Q 2014 – oliot 1.1
(provide EPCIS 1.1,
strengthened to support
food industry)
 2015 – oliot 2.0 (support
internet of things,
merging auto-id lab,
KAIST’s Epc sensor
network, STIS and more)
Oliot Release Plan

Slide 31
Conclusion
ID is the most important feature to distinguish smart things (product, computing
devices, etc.).
Oliot is the EPCglobal-based ID-centric IoT Platform.
We are looking for collaborators:
- developing open sources together such as GS1 source, GS1 digital
- companies who do business with our oliot
- architecting IoT world including food SCM and safety systems, health
care/medicare, retail systems
