Abstract: A method and architecture is described that discovers software application metadata and generates data access applications based on the discovered software application metadata. The discovered metadata along with handcrafted metadata goes through a discovery process and is converted into common, generic abstract metadata objects. The abstract metadata objects then go through an instantiation process to be translated into concrete metadata objects that represent the unique configuration, context and terminology of the source software application. The concrete metadata objects can be generated into numerous forms for the purposes of data access and information sharing. The system also has upgrade protection.

Abstract: A capsulectomy apparatus which comprises a console, a handpiece and a needle. The handpiece operates from a vibrating transducer which drives a rod within the sleeve of the needle for actively engageing the anterior lens capsule which is to be severed. The head of the needle which engages and cuts the anterior lens capsule of the eye has a specific angular relationship with the rod within the needle. Also, the cutting edges and surfaces associated with the head of the needle have a specific configuration for enhancing the cutting quality of the apparatus. The needle is disposable and specifically configured to be removeably affixed to the handpiece.
