Hello, I'm half-way through rewriting nod.txt to use the terminology in mkgmap's routing code, and I'm looking for input regarding the naming of arcs and links. In the current version of nod.txt, I called any of the pointers between nodes "links", and called the "arcs" we're writing now "direct links", while the "links" we're not writing yet are called "indirect links". On the other hand, libgarmin uses arcs and links, and mkgmap's source code has just arcs for the moment. Consistency would be nice. Does anyone have a suggestion for a new term encompassing both arcs and links? I'm finding myself writing a lot of "arc/link", and distinguishing them as "direct something" vs. "indirect something" would make the text a lot clearer. What do you think of using the word "edge" (as in an edge of the routing graph)? arc = direct edge link = indirect edge If we ever want to write links, it would probably make sense to base RouteLink and RouteArc in a common superclass, which would also benefit from an umbrella term.
