<p>A content provider manager has been developped for use in an information service such as a portal or desktop application to provide for 'pluggable' content that may be modified simply through changes to the set of content provider components encoded in a repository therefor. Content providers served to clients (e.g., browsers) by an information service are dynamically loaded and instantiated within the execution environment of the information service in correspondence with changes in the repository. In some configurations, a single repository provides a mechanism for additions to, removals from and/or changes in the set of content providing components served by multiple information service installations. Although the techniques described are more generally applicable, they are particularly useful in implementations of dynamic content applications, including user customizable web portal and personalized desktop, e.g., webtop, applications, wherein a suite of content provider interfaces are provided and the content provider interfaces are separately supported, maintained, owned, licensed, etc. or provide content for which a given user or client application may be separately authorized, configured, enabled or licensed.</p> |
