The World Wide Web was designed originally as an interactive world of shared information through •.vhich
people could communicate with each other and with machines_ Since its inception in 1989 it has grown
initially as a medium for the broadcast of read-only material from heavily loaded corporate servers to the
mass of Internet connected consumers. Recent commercial interest, its use within the organization under
the "Intranet" buzzword takes it into the domain of smaller, closed, groups, in which greater trust allows

and personal information systems_ Other interesting developments ,.vould be the increasingly interactive
nature of the interface to the user, and the increasing use of machine-readable information with defined
semantics allowing more advanced machine precessing of global information, including machine-readable
signed assertions.
