Patent ID: 7831512

Claim:
A method for creating within a primary content of a digital medium a vacancy, the vacancy including a spatial and/or temporal region within the primary content comprising: defining the vacancy with at least one data processing system comprising at least one memory for storing instructions and at least one processor for executing said instructions by associating attributes that describe the vacancy with the vacancy; reserving the vacancy, with the at least one data processing system, as a designated region in the primary content of the digital medium to be filled by a secondary digital content whose attributes match those of the vacancy; wherein the attributes of the vacancy are used by the at least one data processing system to determine how and/or when the vacancy is to be filled by the secondary digital content, wherein defining the vacancy comprises defining dynamic attributes among the vacancy attributes, wherein values of the dynamic attributes are resolved in the process of transmitting information about the vacancy to a service provider for content to fill the vacancy, wherein the values are resolved from properties of the ambient content, or from properties known to an application software that interacts with the vacancy, or from consumer identifying properties, or from any resolvable value that can be mapped to a dynamic attribute in the process of transmitting the vacancy.
