Hello,
I am a bit worried about the preservation of the cards and decks. Basically because the formats used lack any kind of descriptive element that could help either future users or researchers. For this reason I am proposing an archival format to help with that task.
I invite you to participate in the debate either there or here. If you have any idea about what fields would be needed to be created for metadata, don't hesitate to give your opinion.
In any case, thank you very much!
Jaume
