That can be a challenge, too. Again, without knowing what you currently have (or make) try to make it clear and simple leaving room for future expansion. Also, be as descriptive as you can because you can add lots of meta-data to SW files that is searchable. For example, your part numbers would be XX00000 and your configurations could be a -A1 or -11, etc. Then in the description box you could describe the part, so if someone doesn’t know a part number, they can search by description and find it in the future.
