The
layout of a typical web portal is
described by Howard Strauss in his article "Web Portals: The
Future
of Information Access and Distribution."25
The portal interface is normally
divided into "columns" that contain "channels" of
information. This information may be "channel level alerts, text,
multi-media of every stripe, links to information and applications,
navigation,
search, help, and cameos."26
A "cameo" is a piece of data or an
application from another source, that the user can access from within
the
portal. A "data cameo" is a small amount of information that the user
can view while an "application cameo" enables the user to enter data
into the cameo that will be passed on to the external source. For
example, a
user may wish to search Yahoo! on a particular topic without leaving
the
portal. In this case, the Yahoo! search box could be included in the
portal
interface. Strauss also discusses some issues relating to the design of portals. Firstly, the level of "customization" - or the extent to which a portal can be customized to suit the needs of the individual or organization - and of "personalization" - the extent to which the user can adjust the content, layout and other aspects of their own page to fit their individual needs.27 Also, will be there be a single interface or more than one page and, if the latter, how will the user be able to navigate between the pages? When
designing a portal or a gateway
the key issues are usability and navigation. It is important to know as
much as
possible about the users themselves, namely how they search and the
nature of
their information needs. If a user is not able to find the information
that
they require easily and successfully then the portal or gateway is of
no
practical use. It is therefore best to design the portal based on the
needs of
users with the least technical knowledge.28
A simple interface that is easy to
understand and the ability to produce timely and relevant information
are
integral to any design.
