I can't point to the exact conversation, but I think the goal is to make the current 'brand' to instead be 'creator', 'producer' or 'developer' (don't think the ideal term as confirmed yet which is why it's still 'custom brand'). By this I mean the person or company who put the project together. Sometimes this will be the artist, manufacturer, seller, etc, other times a mix and maybe some of it isn't known. A new 'creator' is only added as an option if it is substantial (3 or more decks?) and until then remain in the NULL (aka empty or 'unknown') category. Since the primary focus of the database is on modern decks, vintage is a catch all (I suppose for decks older than 20 years taking the common rule). Which by the way, I also consider all TRUE replicas vintage (Cotta replicas yes, Origins no).
In the current structure I would take the flow chart to be
If you know the 'creator' which is clear and it's an available category then it goes there
If it is older than 20 years it goes in vintage
All others go under NULL
Another possible future addition would be the creation of new fields to record additional attributes:
Manufacturer
Brand (already handled via naming convention)
Artist
etc.
If rhu is able to implement the
User defined values a lot of the categorizing/sorting could be solved on an individual basis. This would be good for features that only a small subset of users would need or care about. Since this could include checkboxes you could specify multiple values....Hmm, perhaps having a user defined set of text fields would help as well so somebody could implement type, specialty, etc on their own more easily. I'll update it.
I also wonder if perhaps a comma separated 'tag' field would be useful at the database or collection level. That would seem to be a simple addition, but the handling, searching, reuse, etc of it would be a major undertaking. Perhaps a future discussion.
As for the dazzle's original concern with vintage, yeah it will get to be a huge grouping as more are added, possibly MASSIVE. My thought is rhu needs to decide how to handle the issues above since if we end up with additional attributes added to the decks then adding things like region, souvenir/advertising (I would combine these since they often overlap), facsimile/reproduction, etc would be a natural addition. If not and the current categories is all that we have to work with for months/years to come, then splitting Vintage into 'Vintage (facsimile/reproduction)', 'Vintage (souvenir/advertising)' and 'Vintage (all other)' would be better.
