Open Language for the Internet of Things

Open Language for IoT (Oliot) is an ID-based IoT framework.

– Based on GS1 standard ID (e.g., URI-convertible GTIN)

Goal

– Is to build a ID-based framework to identify, capture, control and share information

about smart things

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
