Business to business information environment with subscriber-publisher model

摘要

The invention includes a data processing system, a method and a business method. The method links multiple parties: a “publisher”, a “Subscriber”, and an intermediary information exchange engine which facilitates information exchange between the publisher and the subscriber over a data network (typically the public network known as the “Internet”). Metadata is transferred from the publisher to the subscriber, via the intermediary by application of a schema transform applied in software run by the intermediary. Normalized data is transferred substantially without modification from the publisher to the subscriber, provided that the intermediary is able to verify that the subscriber has been previously authorized to receive the particular data. Subscriber status is specified for each distinct type of data, by previous consensus of the first and second parties. Denormalized data is transferred between the publisher and the subscribers, via the intermediary, according to an equivalence transformation applied by the intermediary. First, subscriber status with respect to a particular set of data is verified by the intermediary for the requesting subscriber. Next, denormalized information from a publisher is processed by the intermediary in a transform mapping program, and a provisional equivalence is proposed by the program. The provisional equivalence is sent to the subscriber for verification.
