<p>Self-customising content is delivered to users of an information distribution system such as the World Wide Web (3). A content definition entity (6; 106; 206) contains source content data (33 - 40; 132 - 139; 232 - 239), e.g. image or sound data, and control data or instructions (16, 25; 116, 124; 216, 224) defining the selection or modification of the the source content data in the light of local circumstances, e.g. type of web browser, user name, age or sex, or time of day, to produce object content data which is actually presented to the user. The selection or modification is performed at the user's client station (1). A web-based development tool for content definition entities (6; 106; 206) allows a user to create a content definition entity (6; 106; 206) at a server site (100) using a web browser and then download the completed entity.</p> |
