Create a form in google docs that populate a spreadsheet?
A lot of the basics could be spreadsheet, but there is a lot of ancillary info, pictures, scans, multiple previous owners etc, so it will need to be a relational database.
It’s the sort of thing someone who knows a bit of code could kludge up, but the end-users are more expert in Victorian technology, and my code experience is years decades out of date. 🙂
I could prototype it in my old version of FileMaker while trying to find something end-user simple, but I’d rather not do it twice. I could run-time it, but the danger is deliberate obsolescence which is less likely with open-source.
