### Documents and Methods
Documents are JSON strings that contain *meta-data* (properties, like a filename)
and *attachments* (optional content, for example a base64 encoded image).
and *attachments* (optional content, for example *image.jpg*).
jIO exposes the following methods to *create*, *read*, *update* and *delete* documents
(for more information, including revision management and available options for
each method, please refer to the documentation):
// create and store new document
jio_instance.post({"title": "some title"}, function (err, response) {

### Example
This is an example of how to store a video file with one attachment in local
storage . Note that attachments should best be added inside one of the available
document callback methods (success & error or callback)
storage. Note that attachments should be added after document creation.
// create a new localStorage
var jio_instance = jIO.newJio({
"type":"local",
"username":"user",
"application_name":"app"
var jio_instance = jIO.createJIO({
"type": "local",
"username": "user",
"application_name": "app"
});
var my_video_blob = new Blob([my_video_binary_string], {
"type": "video/ogg"
});
// post the document
jio_instance.post({
"_id" : "myVideo",
"title" : "My Video",
"videoCodec" : "vorbis",
"format" : ["video/ogg", "vorbis", "HD"],
"language" : "en",
"description" : "Images Compilation"
}, function (err, response) {
if (err) {
}).then(function (response) {
// add video attachment
return jio_instance.putAttachment({
"_id": "myVideo",
"_attachment": "video.ogv",
"_data": my_video_blob,
});
}).then(function (response) {
alert('Video Stored');
}, function (err) {
if (err.method === "post") {
alert('Error when posting the document description');
} else {
// if successful, add video attachment (base64 encoded)
jio_instance.putAttachment({
"_id": "myVideo/video",
"_data": Base64(my_video),
"_mimetype":"video/ogg"
}, function (err, response) {
if (err) {
alert('Error when attaching the video');
} else {
