We haven't really. The importance of the flatness is only in assigning=20
importance to the entities. When we put the geometry all in one level, the=
=20
circles are as important as the lines and their ID's are sequential. That'=
s=20
because the entity needs to have the ability to be persistent.
Hmm. Even if it changes from a line to a circle?
Layer entities, however, do not need to share a list of ID's with the=20
geometry. They could, but it seems to make more sense that they don't.
I guess then that the hierarchy breaks into a few toplevel types.
layer
object_style
text_style
mark_style
geometry
line
polyline
arc
circle
mark
text
image
block (?)
xref
The question about blocks is where their toplevel lives if it's inside of t=
he=20
drawing. The block will need an entity like "5.yml" for insert point, etc=
=20
(this entity then points to the block (or xref) toplevel.)
>do we need separate sub-directories for the header info, or just one?
maybe header/layers/, etc
Should styles be grouped together?
The issue here is that you are likely to get some helpful relationships fro=
m=20
having the layer or styles entities in a directory for that type. For=20
instance, you might have a style editor that only opens the files in styles=
/.
Sorry I can't be more help right now. Looming deadline on Friday.
