A virtual business transaction is implemented between a first virtual world and a second virtual world by providing a searchable catalog that includes one or more items each comprising a virtual good, a virtual service, a real good, or a real service. An object representation is stored for each of the items. Each of the stored object representations is associated with metadata comprising any of digital rights metadata, ownership metadata, identity metadata, payment method metadata, or currency detail metadata. A set of transformation algorithms are established that are customized through a rule set. A request is received specifying a copying, modifying, or reselling of an item selected from the items in the searchable catalog. The copying, modifying, or reselling of the item from a first virtual world to a second virtual world is implemented using the set of transformation algorithms. An exchange of virtual currency is implemented between the first virtual world and the second virtual world using the set of transformation algorithms.
