+REST API
+==========================
+[Serval Project], May 2014
+
+[Serval DNA][] presents an HTTP REST API for interacting with Serval MeshMS and Serval Rhizome bundles
+
+CORS (Cross-Origin Resource Sharing). Cross-origin requests are accepted from any port on 'localhost' or '127.0.0.1'.
+
+The REST API was funded by a [grant][] from the [New America Foundation][NAF]'s [Open
+Technology Institute][OTI].
+
+Authentication
+--------------
+
+The REST API implements [HTTP basic authentication](http://en.wikipedia.org/wiki/Basic_access_authentication), configured in the [Serval DNA configuration][].
+
+To see how to configure usernames and passwords, see the [Serval DNA configuration]().
+
+MeshMS API Methods
+------------------
+
+### List Conversations
+
+### `GET /restful/meshms/<sid>/conversationlist.json`
+
+### List Messages (view Conversation)
+
+### `GET /restful/meshms/<SID1>/<SID2>/messagelist.json`
+
+### List New Messages (since <message token>)
+
+### `GET /restful/meshms/<SID1>/<SID2>/newsince/<token>/messagelist.json`
+
+
+### Send New Message
+
+Used to send a message from one SID to another. Does not require an existing conversation to send messages.
+
+### `POST /restful/meshms/<SID1>/<SID2>/sendmessage`
+
+The POST attributes that may be used are:
+
+ * message: The message being sent.
+
+ When sending this message, SID1 must be an identity present in your keyring.
+
+### Mark Messages as "Read"
+
+Serval stores an offset for each conversation indicating up to which message has been read. This means that specific messages cannot be marked as read, instead every message up to a point is marked as read.
+
+To mark all messages to a SID as read
+
+### `POST /restful/meshms/<sid>/readall`
+
+To mark all messages in a conversation as read
+
+### `POST /restful/meshms/<SID1>/<SID2>/readall`
+
+To make all messages in a conversation up to a specific message (by its conversation offset) as read:
+
+### `POST /restful/meshms/<SID1>/<SID2>/recv/<offset>/read`
+
+## Rhizome API Methods
+
+TODO. For now, see the [rhizomerestful tests]()
+
+
+JSON format
+-----------
+
+The output of lists from the REST API uses the following structure:
+
+    {
+        "header":[".token","_id","service","id","version","date",".inserttime",".author",".fromhere","filesize","filehash","sender","recipient","name"],
+        "rows":[
+            ["-luCgeURRKqvbRKQilANXwcAAAAAAAAA",7,"file","F81645C6693A98EB4D2727A7A3D9F478FF77CC60F68949679BFD2A7C65A29E89",1384921558580,1384921558581,1384921558648,"A8BFD18D5BF6E005E96E62188F553F0149B10AD03B47B7A35181457B2A1ABF69",1,1006,"A49C795AE4687CB14F6F1F01265C1DC6472935B125F52ADE4F166A31770E508AF2E0AF9F48D9F6826D60C7B5B820C63028EFD78AD32B9EBA5E43A2B60D74C9E8",null,null,"file6"],
+            ...
+        ]
+    }
+
+This is more compact than the most convenient JSON representation, which would be an array of JSON objects. An array of JSON objects would redundantly repeat all the header labels within every single object. This representation can easily be transformed into an array of actual JavaScript objects.
+
+To do this transformation in JavaScript, use a function similar to the following
+
+    function decompressServalJson(compressed) {
+        var header = compressed.header;
+        var rows = compressed.rows;
+
+        var records = [];
+
+        if (header === undefined || rows === undefined) {
+            throw "Undefined rows or headers for Serval object\n" + JSON.stringify(compressed);
+        }
+
+        for (var i = 0; i < rows.length; i++) {
+            var row = rows[i];
+            if (row.length != header.length) {
+                console.error("Illegal row/header pair in Serval object" +
+                    "\n" + JSON.stringify(header) +
+                    "\n" + JSON.stringify(row));
+                continue;
+            }
+
+            var record = {};
+            for (var j = 0; j < header.length; j++) {
+                record[header[j]] = row[j];
+            }
+            records.push(record);
+        }
+        return records;
+    } 
+
+POST requests
+-------------
+
+Servald only allows POST requests to be [submitted using multipart/form-data](https://github.com/servalproject/serval-dna/issues/82) as blobs with explicitly defined encoding.
+
+An example request to send a message using CURL is shown below.
+
+    curl \
+         --basic --user harry:potter \
+         --form "message=Hello World;type=text/plain;charset=utf-8" \
+         "/restful/meshms/<SID1>/<SID2>/sendmessage"
+
+
+The equivalent JavaScript for sending this request would be
+
+```
+var SID1 = 'foo';
+var SID2 = 'bar';
+
+var address = "/restful/meshms/" + SID1 +"/" + SID2 + "/sendmessage";
+
+var username = 'demouser';
+var password = 'demopassword';
+
+var params = new FormData();
+params.append('message', 'Hello World');
+
+var xhr = new XMLHttpRequest();
+
+xhr.onreadystatechange = function () {
+	if (xhr.readyState == 4) {
+    console.log(xhr.response);
+	}
+};
+
+xhr.open("POST", address, true);
+xhr.setRequestHeader('Authorization', 'Basic ' + btoa(username + ":" + password));
+xhr.send(params);
+```
