A computer implemented system for obtaining, storing and displaying cells of visual information such as Internet World Wide Web pages includes a display unit, a storage system for storing cells in eXtensible Markup Language (XML) format, and a communication unit for obtaining data objects or documents which can be in a plurality of different formats from the Internet and other external sources. A cell designer enables a user to create a view including a plurality of selected cells, each of which includes at least one data object. A display generator obtains the selected data objects from the storage system and generates the view for display by the display unit. A conversion unit converts data objects obtained by the communication unit into XML using eXtensible Style Language (XSL) and Document Type Definitions (DTD), and the cell designer creates the specified arrangement using XSL and DTD. The conversion unit includes a plurality of factories for converting data objects obtained by the communication unit from different respective formats into XML, and a factory manager for determining a format of a data object obtained by the communication unit and assigning it to a corresponding factory. An event manager causes the communication unit to obtain updated versions of outdated data objects from the external sources. A list unit stores a list of users and cells requested by each user, and the event manager sends notifications of the updated versions to users who have requested the specified data objects. |
