Each day more and more devices are coming online, adding to the ever-growing Internet of Things (IoT). Analysts agree the IoT will grow to many billions of devices over the next decade.

The challenge for the IoT ecosystem is to ensure these emerging IoT devices can connect securely and reliably to the Internet and to each other.

The IoTivity project was created to bring together the open source community to accelerate the development of the framework and services required to connect these billions of devices.

The IoTivity project is sponsored by the Open Interconnect Consortium (OIC), a group of industry leaders who will be developing a standard specification and certification program to address these challenges.

IoTivity will deliver an open source reference implementation of the OIC standard specifications, yet will not be limited to those requirements.

We invite you to explore the site, download the code and start participating today.

The IoTivity architectural goal is to create a new standard by which billions of wired and wireless devices will connect to each other and to the internet. The goal is an extensible and robust architecture that works for smart and thin devices.

The architecture will provide a roadmap for manufacturers and service providers, including:

Common solution
Define a communication and interoperability solution across multiple product markets such as Consumer, Enterprise, Industrial, Automotive,  and Health, and across operating systems, platforms, communication modes, transports and use cases.

Established protocols
Reuse existing and establish new common communication protocols for discovery and connectivity across multiple transports.

Common approaches
Apply common approaches for security and identity.

Defined commonalities
Define common profiles, object models, and developer application programming interfaces (APIs).

Interoperability
Promote device and application interoperability across markets and use cases.

Innovation opportunities
Provide opportunities for innovation and allow for differentiation.

Necessary connectivity
Connect everything from the smallest wearable to the largest smart car.

The IoTivity framework APIs expose the framework to developers, and are available in several languages and for multiple operating systems. The APIs are based on a resource-based, RESTful architecture model.

The framework operates as middleware across all operating systems and connectivity platforms and has four essential building blocks:

1. Discovery
   IoTivity discovery supports multiple discovery mechanisms for devices and resources in proximity and remotely.
2. Data transmission
   IoTivity data transmission supports information exchange and control based on a messaging and streaming model.
3. Data Management
   IoTivity data management supports the collection, storage and analysis of data from various resources.
4. Device management
   IoTivity device management supports configuration, provisioning and diagnostics of devices.
