It occurs to me to look to graph theory for some
terms, as it has vertices & .... "edges" which connect
them. Hmmm, here's one definition popping up:
An edge is (together with vertices) one of the two basic units
out of which graphs are constructed. Each edge has two (or in hypergraphs, more)
vertices to which it is attached, called its endpoints.
Edges may be directed or undirected;
undirected edges are also called lines and directed edges are also called arcs or arrows.
In an undirected simple graph, an edge may be represented as the set of its vertices,
and in a directed simple graph it may be represented as an ordered pair of its vertices.
An edge that connects vertices x and y is sometimes written xy.
Given this, I'd replace "edge" --which has unwanted connotations, IMO--
with "end" perhaps --esp. as in some of my yet-developing
knots thinking, I have terms "tangle" and "end" :: the first being
the entangled knotty mass ("nub", D.Chisholm might say)
from which emerge however ever many ends there are (and,
e.g., I see end-2-end joints & eye knots as equally 2-tangles,
with 2 pieces of material, each with 2 ends; 4 ends thus emerge
from such a tangle; and a "knot" is that tangle given a loading
profile showin which ends are loaded vs. which other(s).
"span" comes to mind, too. (With my *tangle* thinking,
ends are an exit from the object only to be assigned loading;
but in your net thinking, those parts are going to/from,
with objects both ways; "span" has more this connotation.
(And, re graph theory, I see netting as UNdirected,
just 2-item (knot) sets w/o specific order.)
