I am looking for any datasets which might contain generic versions of Assemblies, Bills of Materials (BOMs), Materials Takeoffs, Associated Lists, or other hierarchical/ontological representations of basically any type of physical/manufactured products/goods I can find.
The data does not have to be "pristine" and doesn't even have to be 100% accurate. I am just looking for "as close as I can get" on as many different types of products as possible.
Any common format (JSON, XML, CSV, Excel, etc.) is perfectly fine. I am quite happy to massage or compile the data into a more manageable form. I simply need the data--and as much as possible.
Does anyone happen to have any idea where I might be able to find such information?
Thank you so very much in advance!
