Furthermore, URIs can be bookmarked, exchanged
via hyperlinks and, given their readability, even printed on
billboards for advertising [26].
WS-* initially lacked a standard addressing mechanism and also
relied on URIs for identification of messaging end-points and WSDL
service interface descriptions. More recently, WS-Addressing [44]
was introduced to represent addressing information through the
definition of “end-point references”. This standard language augments the information stored in URIs with additional metadata, but
lacks the conciseness and readability properties that ensured the
success of URIs.
