OpenWiFiMap is a database and map for free network WiFi routers (freifunk and others, too!).
This is the database part of the openwifimap. Make sure to also take a look at the openwifimap HTML5 app running at openwifimap.net.
This is a (possibly incomplete) list of API installations:

The following fields are always present in a node document:
{
"_id": "a4d15a897f851938a799e548cc000eb0", // required by CouchDB: document id
"type": "node", // tells couchDB that this is a node
"hostname": "myhostname", // hostname == display name
"latitude": 52.520791, // latitude in degrees, range [-180,180], EPSG:3857
"longitude": 13.40951, // longitude in degrees, range [-90,90], EPSG:3857
"updateInterval": 6000, // time between consecutive updates in seconds
"ctime": "2013-05-09T17:49:21.821Z", // create time (automatically inserted by update handler, see below)
"mtime": "2013-05-10T17:50:22.123Z" // modify time (automatically inserted by update handler, see below)
}While nothing is wrong with only pushing the required fields, you probably want to provide further information about the node. There are several fields that are recognized by the openwifimap couchapp, while you can add any other information about your node. Just make sure that you provide valid JSON and use the recognized fields correctly.
The links field's value should be a list of links to neighbor nodes. Links between neighbors will be shown as lines in the map. The quality field is required for each field.
"links": [
{
"id": "a4d15a897f851938a799e548cc0017e7", // document id of the neighbor node
"quality": 1 // quality of the link, range [0,1], 0==no link, 1==perfect link
},
{
"id": "host2",
"quality": 0.39016
}
]You can provide additional fields in link objects, for example the used routing protocol and its data in a mesh network (such as OLSR or B.A.T.M.A.N. in freifunk networks):
"links": [
{
"id": "host2",
"quality": 0.39016, // for olsr, 1/etx can be used (be aware of dividing by zero)
"olsr_ipv4": { // additional data
"local_ip": "104.201.1.1",
"neighbor_ip": "104.201.1.18",
"lq": 0.533,
"nlq": 0.732,
"etx": 2.5631
},
"olsr_ipv6": { // additional data
"local_ip": "2002:4e35:28e7:bd9d::1",
"neighbor_ip": "2002:4e35:28e7:be2c::1",
"lq": 0.533,
"nlq": 0.732,
"etx": 2.5631
},
}
]Each node can have several network interfaces. Provide as many details as possible to improve the presentation of the node in the map and on the detail page of OpenWiFiMap.
