Abstract: The invention is a system and method, embodied in infrastructure platforms, that implements the suitable means of generating, storing, manipulating, distributing and utilizing marketing and sales oriented metadata that can be associated with goods and services offerings. It uniformly treats coupons, ads and similar marketing and sales information products as metadata about goods and services. It makes provisions for the goods and services metadata to be delivered via wireless technologies and devices. It allows consumers to trade or barter coupons and other metadata, according to individual needs, via an intermediary exchange or clearinghouse. It supports graded coupons and similar metadata, by allowing the redeemable value of such a coupon to be correlated with age. It supports the specialization, customization and personalization of the metadata and its redeemable value to be correlated with the roles, aspects and concerns of both producers and consumers of goods and services metadata.
