# TaOwner The **TaOwner** is the entity who owns a [Transactive Device](transactive-device) in the real world, and its associated [TerminalAsset](terminal-asset) in GridWorks. Ownership of a TerminalAsset by the TaOwner is established by a [TaDeed](ta-deed), which is an Algorand object. The TaDeed for a TerminalAsset will change from time to time, for example as the [GNodeAlias](g-node-alias) for the TerminalAsset changes. The GNodeAlias is a structured identifier that helps capture the topology of the electric grid, and as such it is mutable, perhaps changing a handful of times over the lifetime of the GNode. The TaOwner will often be a human. It is not appropriate, therefore, to expect an action from the TaOwner when the TaDeed changes. This is done by putting the TaDeed into the care of a [TaDaemon](ta-daemon) application. _Back to [Lexicon](lexicon)_
