1. A computer-implemented method of documenting a design of a transformer, the method comprising: generating a metadata text file describing a physical layout of the transformer, the metadata text file being written in a metamarkup language and comprising component elements describing components of the transformer, respectively, the component elements being arranged in a hierarchical format that corresponds to the physical arrangement of the components in the transformer; analyzing the metadata text file to determine design information comprising numbers and types of the components of the transformer and their interrelationship; opening an electronic document; and creating a drawing of the physical layout of the transformer in the opened electronic document using the determined design information, the drawing including graphic elements representing the components of the transformer, respectively.
