Collectors, Intermediate
A collection inventory that survives changing apps
Use stable identity fields and a separate owned-copy layer. The same species, local number or artwork can appear on many different releases.
For intermediate readers, read 8 Nov 2026.
Build the identity key
Store card language, territory if relevant, set ID, local number, edition, finish and stamp. Keep external provider IDs as additional references rather than the only definition. That way, a changed app or corrected provider mapping does not erase what you actually own.
Store each copy separately
Condition, purchase date, cost, seller evidence and storage location belong to the owned copy. Two copies of the same printing can have different condition and acquisition histories. A species checklist should be a view of those records, not the underlying database key.
Export before committing
Choose a portable text/CSV representation and keep a private backup. Avoid exposing precise locations or a valuable inventory publicly. This prototype has only session checklists, not a cloud vault; checking a box does not create a backed-up collection record.
