In some embodiments, a computer-implemented method for role-based and attribution-tracking collaborative design based on manufacturing constraints is disclosed. A method comprises: receiving product description data for an interactive design; wherein the product description data for the interactive design comprises data for generating a graphical visual representation of a physical product that is capable of custom manufacture with a plurality of variable product attributes; parsing the product description data to identify a plurality of global-key-values pairs journaled within the product description data and associated with contributors; based on, at least in part, the plurality of global-key-values pairs, constructing an ownership-attribution tree; based on the ownership-attribution tree, generating manufacturing instructions for customizing the physical product and according to the plurality of variable product attributes; and transmitting the manufacturing instructions to a product customization server to cause a manufacturing entity to proceed with generating a customized product based on the manufacturing instructions.
