Abstract: Technology is described for generating a search index. Device information associated with a customer may be identified. A device attribute included in the device information may be identified. The device attribute may include an attribute name and an attribute value. Key-value pairs may be formed for device attribute included in the device information. The key-value pairs may include a first key-value pair for the attribute name and a second key-value pair for the attribute value. The search index may be generated to include the key-value pairs for the device attribute included in the device information.

Abstract: Technologies are disclosed for providing a device registry service for devices that communicate over a network. The devices are configured as Internet of Things (IoT) devices. The devices are registered and classified as various types. Based upon the classification, interfaces are provided for the registered devices by the registry service if the devices do not already include them to allow for interaction and control of the devices. New interfaces can be provided to the service by various parties including manufacturers and system integrators to expose additional capabilities of the devices and create additional functionalities. The new interfaces are generally made available to all users of the registry service.
