Abstract: One variation of a method for normalizing manufacturing data includes: identifying a type of the digital component description document, including a set of part descriptor entries describing a set of physical parts, based on categories of physical parts described in part descriptor entries within the digital component description document; accessing a set of part descriptor rules corresponding to the type of the digital component description document; detecting deviation of a part descriptor entry, in the set of part descriptor entries, from a part descriptor rule in the set of part descriptor rules; at the user portal, serving a prompt to manually correct the part descriptor entry; and, in response to alignment between the digital component description document and the set of part descriptor rules, importing the set of part descriptor entries into the component library.
