Attributes of type 5 are uniform resource locators (urls) represented as byte vectors. Attributes of type 5 of a node N are urls of Logiweb pages whose reference equals the address of N. The timestamp of an url indicates the server time when the url was added to the state. Attributes of type 5 are referred to as 'url' attributes. The url attribute list is required to be strictly chronological to allow future extensions of the Logiweb layer 0 protocol in which url attributes are referenced by timestamp.

Logiweb servers perform their main task - translating a reference R to an url U - by looking up an url attribute of the node with address R.
