Here we will define the syntax and semantics of dpath, which is the path traversal format for dmap.

It describes the existing dpath definition as well as a future-proof way of extending it. At the moment, this just means reserving all special characters, but we will define some as private use area so you can start experimenting with your own extensions right away.

Besides the two that are defined already, we list a few runes for which we already have specific use cases.

dpath ::= step*
step  ::= rune name
rune  ::= ':' | '.'
name  ::= [a-z]

Definitions:

• . dot
• : lock

Reserved glyphs:

dquery:   !?@#$()
reserved: everything else
