hi guys,
in my experience there are really 3 cases that are worth
distinguishing from a users perspective.
#1 - i want all the properties of a node in one response
#2 - i want all the childnodes of a node and their properties in one response
#3 - i want all the childnodes and properties at an infinite or
arbitrary level in
one response
i would argue that #1 & #2 make up 90% of all the requests.
#1 & #2 are not a big deal with respect to serverside caching since
they are usually very cheap.
so i would argue that with respect to caching we should probably take
care of the expensive #3...
personally, with ujax in mind, i certainly would argue that the default
behavior is important for a method like ujax.getContent("/mynode")
should be to just get the proprties of a node in a shallow manner.
which to me hints that this should probably also be the the default
behaviour of "/mynode.json" (== "/mynode.0.json").
to align with the webdav propfind "Depth" header i would recommend to go with
"/mynode.infinity.json"
regards,
david
