The Case for an Open IoT ‘Data Fabric’ for Smart Buildings Integration. Memoori was joined by Dialog Semiconductors to discuss the recently standardized IoT Access Protocol (IAP) and how it may solve some of the problems that arise from integrating Smart Building systems. The Webinar will also discuss an example case study of LoRa sensors using the SmartServer Edge running IAP.

Case for an Open IoT Centric Data Fabric
Solution to the integration problem relies on an IoT
centric data fabric that…
• Seamlessly connects any IoT end points with
each other and with clients and applications
• Provides access to device data securely using
web friendly API from anywhere
• Enables a resilient, decentralized edge
computing architecture
• Runs anywhere
IAP is an open CTA standard – CTA 709.10
IAP is in the standardization process with ANSI and CEN
Data Abstraction

Web APIs
Applications (AI, Analytics,
Automation….)

The Future of IAP
▪ IAP is an open CTA standard – CTA 709.10
▪ CTA has forwarded the IAP standard to ANSI for ANSI
standardization
▪ IAP is in the standardization process with CEN
▪ After ANSI and CEN standardization, the IAP standard will
be submitted to ISO for international standardization
▪ IAP documentation is available at
http://iecdocs.diasemi.com/
▪ Open source IAP application examples are available at
https://github.com/izot/smartserver-iot
▪ Edge Server information available at
