CROSS-DOMAIN LINKING OF DATA TYPES

In one implementation, a computer-implemented method can include receiving, at a first server corresponding to a first domain, a request from a client computer for a vector graphics file that includes instructions that implement a first method. The method can further include sending the vector graphics file to the client computer, the client computer having received a library file from a second server corresponding to a second domain, wherein the library file includes instructions that implement a second method to direct calls to the first method, and wherein executing the vector graphics file and the library file causes the client computer to perform operations. The operations performed by the client computer can include establishing a link between the first method and the second method and directing a call made to the second method with an argument associated with a data type, to the first method using the established link.
