Open catalogue
Set codes anyone can use
Official printed codes come first. Established community abbreviations cover older sets without printed codes.
Canonical codes
Each set has one canonical code and any number of aliases. Codes, full names, and external database identifiers resolve to the same record.
Editions
First edition, shadowless, and unlimited printings are variants of one set rather than duplicate sets.
Registry status
The eight launch games are prepared. Set records appear only after an approved catalogue import; Hansa does not fabricate them.
