Qtopia Data Linking (QDL) is the name given to the protocol and applications governing data linking in the Qtopia environment. QDL is a consistent, global, application-independent API to associate or link data items across applications. The application embedding the link does not require special knowledge of the source application.
Qtopia Data Linking (QDL) provides an API to associate or "link" data items across applications. A QDLLink is conceptually the same as an ordinary anchor on a webpage. A QDLLink has information which uniquely references an object somewhere in the same application, or another Qtopia application. When the user clicks the link the referenced object is accessed. For example, using QDL a user can create a meeting event in Calendar and a link to each person attending the meeting from Contacts. When the event is viewed, hypertext links appear for each linked Contact. Activating a link sends a message to the Contacts application to display that contact. For more information refer to the Qtopia documentation.
Services
Qtopia applications can provide a QDL service. This is achieved by providing a message handler for the application which inherits from the QDLService class.
