Resources may be any type of device, appliance or software that has an API defined using Resource Control Protocol (RCP). RCP is a REST protocol that defines a limited number of operations that work on paths. An RCP path encodes the operation, attributes and data required to form a command that will be executed by the target resource. RCP is a text-based

Protocol that can be carried by many transport layers including IEEE 802.15.4, TCP/IP, UDP, SM-Bus and CAN-Bus.
Resources are managed by a ''Device Server'' which may manage resources that are implemented using multiple different communications technologies. Resources that do not natively implement the RCP protocol, are integrated into the ADRC system using an RML translation layer which is a software module that provides a protocol translation function between the foreign protocol and RCP. The RML translation layer is also responsible for providing an RML description for each of the supported devices of the foreign protocol.
Multiple resources that share a common location or local network form a ''Domain''. Each domain is managed by a device server and resources may be associated with multiple domains if desired. A device server generally executes on a hardware gateway that exists at the edge of the Internet and a domain. Device servers respond to requests from device browsers which may be on the local network or across the Internet. Device servers also receive unsolicited signals from resources and relay them on to clients.
Device manufactures describe their device using RML which is normally embedded into the device at the time of manufacture; however RML may also be provided at a

. When a device is on-boarded to a domain, the RML for the device is retrieved from the device by the device server. When a device browser is used to interact with a device, it fetches the RML from the device server and uses it to create the user interface presented to the user. A device may have one or more RML descriptions thus allowing for varied user experiences to be provided. As well as using RML to create the user interface, the device browser uses RML to construct the RCP commands that implement the device's
