Systems and methods are provided to integrate disparate media services and applications across an organization. The media services are connected to an interoperable media services bus by creating a connector API for each service, thereby enabling the media services to exchange messages in a standardized format related to transactions to be performed involving media assets and/or metadata associated with media assets. Media assets are advantageously transported between different media systems using a transport interface that hides details of the transport operation from the sender and recipient media services. Each media service provides its own file transport parameters defining procedures for obtaining media assets therefrom and writing media assets thereto; the transport service determines particular protocols for each transport operation based on the information provided by the sender and recipient media services.
