Title: normalize pipe

Objective
-------------
- normalize nodes, in other words, fill necessary field using pipe interface

Discussion
--------------
Although no properties except for "path" is required,
it is convinient if nodes have basic properties such as "configure" or "comment".
This pipe fill them using obvious values (`{}` or `""`).
