Abstract

This paper discusses the abstraction and extension of portal systems and definitions of portlets in order for them to become more accessible. A whole/parts perspective is adopted that considers portal systems as a whole and the portlets as parts that need to have some attributes, behaviours and organisation for accomplishing their purpose. A comparison between a portal system and a web site in terms of accessibility is given for identifying the additional requirements of a portal system. According to these, complementary specifications and guidelines are proposed at the design as well as at the implementation level, and suggestions are made for some types of automatic accessibility checking for portals.
