The increasing penetration of the real world with embedded and globally 
networked sensors enables the formation of a Web of Things (WoT), where 
high-level state information derived from sensors is embedded into Web 
representations of real-world entities (e.g. places, objects, creatures). A 
key service for the WoT is searching for entities which exhibit a certain 
dynamic state at the time of the query, which is a challenging problem due to 
the dynamic nature of the sought state information and due to the potentially 
huge scale of the WoT. Below we report on our initial efforts to construct 
such a search engine and the underlying WoT.
