The code available at the link provided by Guido is just a small proof
of concept of the technologies involved.

couchdb is schemaless, so you can send any arbitrary JSON data you wish
to add to a node through HTTP, no need for pre-defined fields.


an example flollows...

get all nodes:

$ curl -X GET
http://127.0.0.1:5984/altermap/_design/altermap/_view/byCollection

{"total_rows":3,"offset":0,"rows":[
{"id":"47ad792d23adcbaa2bed2d48b308bead","key":"nodes","value":{"_id":"47ad792d23adcbaa2bed2d48b308bead","_rev":"1-d49ddf0d694aac4960db062cd739f166","name":"toto","coords":{"lat":-31.801834884076452425,"lon":-64.415228962898254395},"wait":true,"collection":"nodes"}},
{"id":"47ad792d23adcbaa2bed2d48b308c73c","key":"nodes","value":{"_id":"47ad792d23adcbaa2bed2d48b308c73c","_rev":"4-2c00d1b99a8098725076907495d0b598","name":"joseluis","coords":{"lat":-31.802112988096421731,"lon":-64.414783716201782227},"collection":"nodes"}},
{"id":"47ad792d23adcbaa2bed2d48b308d610","key":"nodes","value":{"_id":"47ad792d23adcbaa2bed2d48b308d610","_rev":"1-64ac665949912ee3ab16e7865fdda7cd","name":"flor","coords":{"lat":-31.798967172499931877,"lon":-64.413828849792480469},"collection":"nodes"}},
]}

get a specific node:
$ curl -X GET
http://127.0.0.1:5984/altermap/47ad792d23adcbaa2bed2d48b308c73c

{"_id":"47ad792d23adcbaa2bed2d48b308c73c","_rev":"4-2c00d1b99a8098725076907495d0b598","name":"joseluis","coords":{"lat":-31.802112988096421731,"lon":-64.414783716201782227},"collection":"nodes"}

Add some arbitrary data to the node:

curl -X PUT
http://localhost:5984/altermap/47ad792d23adcbaa2bed2d48b308c73c -H
"Content-Type: application/json" -d
'{"_rev":"4-2c00d1b99a8098725076907495d0b598",
"name":"joseluis","collection":"nodes","coords":{"lat":-31.802112988096421731,"lon":-64.414783716201782227},
"network":"quintanalibre.org.ar", "admin": "(spam-protected)"}'

{"ok":true,"id":"47ad792d23adcbaa2bed2d48b308c73c","rev":"5-05ecb6ce7abafe4becd07fb15042eddb"}


Test that the node now has the new network and admin attributes set:

$ curl -X GET
http://127.0.0.1:5984/altermap/47ad792d23adcbaa2bed2d48b308c73c

{"_id":"47ad792d23adcbaa2bed2d48b308c73c","_rev":"5-05ecb6ce7abafe4becd07fb15042eddb","name":"joseluis","collection":"nodes","coords":{"lat":-31.802112988096421731,"lon":-64.414783716201782227},"network":"quintanalibre.org.ar","admin":"(spam-protected)"}


So... the idea is that routers can use curl to update their data
dynamicaly or even automatically add themselves to the database.

There will be news regarding AlterMap during this week, as we are
preparing a minimal functional version for an event we will be attending
shortly. We will report progress on this list.
