I get the "multiple instance through a storyline" nature of tags, and how a character trait, or subtext, or emotional state might be represented by tags weaving though a story and attached to beats.
However, where do you put things in research like "hair, makeup, wardrobe, age" traits which might be mentioned only once at the introduction of the character so you don't forget it?
Per, any good ideas on where to put character "external" attributes (not traits as you defined them) such as hair, makeup, wardrobe? Are they candidates for singleton tag or a note? It looks like Beats are the only things that can be linked with a script location. Notes dont work like that. Tags are attached with beats. If beats are actions, then they are poor candidates for character "external" attributes.
To be clearer: In my thinking what a character "is" (age, parent, race) and what they are "like" (subtext, emotion, trait?) are two different classes of things. They both might be tracked in a story, but in different ways. A "note" doesn't look like it can be tracked in a story to be used to mention age. So do I use a tag as a "singleton" instance which only surfaces perhaps once in a story but can be attached to a beat so it can be located?
In a screenplay, usually action lines intro a character and describe traits for a director. I suppose one could argue that what winds up in action lines are really beats and tags could represent WHAT trait is being attributed a the time. A character's age may come up multiple times and be significant--is that when it's a tag?
