All REST Monday continues. Except for very large values of "inconsistent" -- like "one or the other doesn't use HTTP" -- I think a little more explanation is needed to support this:
REST-based architectures are not inconsistent with the WFS specification.
Again, the five key principles of REST (use of HTTP is implicit), from Stefan Tilkov again, are:
Give every "thing" an ID
Link things together
Use standard methods
Resources with multiple representations
The last of these is the only one to which WFS 1.0 strictly adheres. WFS does not specify permanent URIs for individual features; does not specify hypertext links among features, types, and services; uses GET or POST, yes, but interchangeably and in ignorance of PUT and DELETE; and does not specify use of HTTP content negotiation to select data formats. All of Tilkov's REST anti-patterns save number 5 (cookies) are written into the WFS specification, and so it still seems to me that WFS is mostly inconsistent with REST.
