[Interop-dev] Common API
Tue Oct 23 18:33:42 CEST 2012
So, we've been talking about it for quite a while.
We really need this, we should start working on it actively to make a
proof of concepts.
I know many of us (included myself) are developing their own API for
Let's agree discuss about this common interchange mecchanism.
I'll start with some thoughts that follow.
Every community surely has at least NODES in their DB, so I'll start
This is a draft of how my JSON list (and I underline that a list view is
different from a detail view, a list view is for example
*/api/v1/nodes/* while a detail view would be /api/v1/nodes/<slug>/
output actually looks like:
+ id: 1,
+ status: 3, name: "Fusolab Rome",
+ elev: 80,
+ is_hotspot: true
*objects and is_hotspot*
Pheraphs "objects" should be "nodes" (in this case) and is_hotspot just
"hotspot". What does hotspot actually means? It means if the node has
some kind of easy 0 conf access to the network (included internet
connection), I mean for example an ubiquiti picostation with 2.4 with
open access. We consider that a useful info here.
Status could be a string, even though a number would make us save some
bandwidth if we would agree to map numbers to stati, that could be done
easily in any language.
Description might be left out for the list view and be kept only for the
detail view to save even more bandwidth.
Pheraphs not evey node db is going to use a slug but I guess we should
make it possible to use it and fallback to the ID if not present.
that is provided out-of-the-box with django-tastypie. It's useful in
case someone needs to paginate or do some other filtering operations.
Don't know if it's useful for the interchange mecchanism but that makes
me wonder, what do you do when you have thousands of nodes?
*splitting the nodes*
Is not a good idea to send a huge JSON file to mobile clients. The info
should be split somehow. I was thinking of splitting data depending on
zones / groups (nodewatcher calls them projects, CNML calls them zones).
clients can download data from the zones they're in, so you if you load
the map of vienna you'll download only the vienna JSON file initially
and other nearer zones/groups/projects will be loaded in the background
as you move around. It should really work in a similar way like google
I think I talked about this with Ralf from Funkfeuer.
Come on, share your thoughts! I guess if we don't start now we'll never
do it ;-P
