Excerpted from "Introduction": "The World Wide Web provides an information delivery infrastructure for various types of digital contents used in daily life. Payment infrastructures such as digital cash, micropayments, and encrypted credit cards have also been established. However, no digital medium or infrastructure that prevents duplicate redemption and enables the trading of various rights, much like paper tickets, has been established yet. We are thus developing a generalized digital ticket system that can circulate any type of rights. A digital ticket is a digital medium that guarantees certain rights of the ticket owner and it includes software licenses, resource access tickets, event tickets, plane tickets, etc. To circulate various types of digital tickets using a common ticket processing system, we proposed a general-purpose digital ticket framework, in which a ticket is circulated by interpreting ticket properties such as anonymity, transferability, and the redemption method, specified in the ticket itself using the XML based Generalized Ticket Definition Language [2]."
