A multidimensional method and apparatus for adaptively characterizing and aggregating data through a secure automated means of database modification, a prioritization and weighting system, a third party enhanced metadata entry and classification mechanism, adaptive and time varying individual personality and preference characterization, and an aggregation and delivery capability which allows for multiple data formats and mediums. Individual characterization incorporates an inference engine which formulates client composite images which vary with time. Asynchronous data interchanges enabled through the use of XML allow for more efficient and effective resource utilization and time. The knowledge system of this invention A) effectively integrates information from diverse sources, B) verifies, adds to or enhances source metadata (product data sheet; article title), and C) searches, queries, retrieves, and aggregates information. Selected product information can be obtained by e-mail without exposure to spamming by using e-mail address translation.
