Very nice project! Curiousity question: since you are taking data dumps once-twice a year, and let's say you also copy the photos as well, do you do any updates incrementally or just replace the old one with new dump?
But you have control over this:
- You can customize what makes an item a duplicate or unique
- You can choose whether to update existing items, and how to update them (what to keep of the incoming item versus the existing one)
