Ok, here is another thought of how to grab this new ‘thing’:
If Types, Collections and Tags are all different perspectives on the same thing (skipping sets for historical reasons), so why not finding a whole new name for it’s combined being?
Lets flip through the combinations:
Tyco
Tycol
Tyta
Tytag
Tycota
Tycotag
Tytaco
Tytacol
Colty
Coltype
Colta
Coltag
Coltyta
Coltytag
Taty
Tatype
Taco
Tacol
Tatyco
Tatycol
Tacoty
Tacolty
Tacotype
Tacoltype
Anything else?
Which one fits best (if any)?
(Actually my favorites are Taco, Tycota, Tycotag, Colty and Tacotype 
)
