A semantics node for managing semantics, the semantics node comprising: a processor ; a transmit/receive element for communicating with a network ; and a memory coupled to the processor , the memory comprising executable instructions that when executed by the processor cause the semantics node to effectuate operations comprising: storing a first plurality of semantics related resources in the memory of the semantics node , wherein each of the plurality of semantics related resources comprises information used to describe the semantics information of another resource; receiving, from a client via the network , a request for a first semantics related resource; when the requested first semantics related resource is one of the first plurality of semantics related resources stored in the memory of the semantics node , transmitting, to the client via the network , the first semantics related resource; characterised in that : when the requested first semantics related resource is not one of the plurality of semantics related resources stored in the memory, retrieving the requested first semantics related resource from a second semantics node , wherein the second semantics node is a parent semantics node of the semantics node . a processor ; a transmit/receive element for communicating with a network ; and a memory coupled to the processor , the memory comprising executable instructions that when executed by the processor cause the semantics node to effectuate operations comprising: storing a first plurality of semantics related resources in the memory of the semantics node , wherein each of the plurality of semantics related resources comprises information used to describe the semantics information of another resource; receiving, from a client via the network , a request for a first semantics related resource; when the requested first semantics related resource is one of the first plurality of semantics related resources stored in the memory of the semantics node , transmitting, to the client via the network , the first semantics related resource; characterised in that : when the requested first semantics related resource is not one of the plurality of semantics related resources stored in the memory, retrieving the requested first semantics related resource from a second semantics node , wherein the second semantics node is a parent semantics node of the semantics node . storing a first plurality of semantics related resources in the memory of the semantics node , wherein each of the plurality of semantics related resources comprises information used to describe the semantics information of another resource; receiving, from a client via the network , a request for a first semantics related resource; when the requested first semantics related resource is one of the first plurality of semantics related resources stored in the memory of the semantics node , transmitting, to the client via the network , the first semantics related resource; characterised in that : when the requested first semantics related resource is not one of the plurality of semantics related resources stored in the memory, retrieving the requested first semantics related resource from a second semantics node , wherein the second semantics node is a parent semantics node of the semantics node . <EOS>
