Open Platform 3.0™ Standards

The O-DEF Standard facilitates interoperability through the use of a common data vocabulary.

The Open Data Format (O-DF) standard is intended to represent information about things in a standardized way that can be understood and exchanged in a universal way by all information systems that need to manage IoT-related data.

The Open Messaging Interface (O-MI) standard connectivity model is similar to that of the World-Wide Web (WWW). Where the WWW uses the HTTP protocol for transmitting HTML-coded information mainly intended for human users, O-MI requests are used for transmitting lifecycle-related information mainly intended for automated processing by information systems.
