Abstract: A method and a computer-readable storage medium configured with instructions that when executed to carry out the method, and a computer system configured to carry out the method. The method includes storing a set of rules in computer-interpretable form in a processing system. The rules allow the expression of a range of possibilities for determination of recognition of items of content and a wide range of actions to take when such determination is made. Using the rules, a processing system can recognize content and possibly act on the recognition results, the recognition and acting according to the stored set of rules.

Abstract: A client/server system is described incorporating methods for managing object availability through semantic object "load sets." By associating a particular "load set" with each object which might be requested by a client, improved object fetching and cache management is provided. Methods are described for managing object fetching and discarding on a per object basis, not on a per page basis. Each "semantic object" is packaged in a "storable," which incorporates dependency lists indicating the context in which the object is to be used (i.e., with which dependent objects). Additionally, a program developer can specify that the set of behaviors is defined at runtime, using "prefetch" primitives provided by the system. This allows an executing application to prefetch objects based on the then-existing dynamics of the system. With this approach, object availability in a distributed object environment (e.g., Internet) is improved.
