+=======================
+Design Document Methods
+=======================
+
+In CouchDB, design documents provide the main interface for building a
+CouchDB application. The design document defines the views used to
+extract information from CouchDB through one or more views. Design
+documents are created within your CouchDB instance in the same way as
+you create database documents, but the content and definition of the
+documents is different. Design Documents are named using an ID defined
+with the design document URL path, and this URL can then be used to
+access the database contents.
+
+Views and lists operate together to provide automated (and formatted)
+output from your database.
+
+A list of the available methods and URL paths are provided below:
+

+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/_design/recipes
+    Content-Type: application/json
+
+The returned string will be the JSON of the design document:

+          },
+       },
+    }
+
+A list of the revisions can be obtained by using the ``revs`` query
+argument, or an extended list of revisions using the ``revs_info`` query
+argument. This operates in the same way as for other documents. Fur
+further examples, see :ref:`api-get-doc`.

+    * **Optional**: yes
+
+* **Return Codes**:
+
+  * **409**:
+    Supplied revision is incorrect or missing
+
+Delete an existing design document. Deleting a design document also
+deletes all of the associated view indexes, and recovers the
+corresponding space on disk for the indexes in question.
+
+To delete, you must specify the current revision of the design document
+using the ``rev`` query argument.
+
+For example:
+
+.. code-block:: http
+
+    DELETE http://couchdb:5984/recipes/_design/recipes?rev=2-ac58d589b37d01c00f45a4418c5a15a8
+    Content-Type: application/json
+
+The response contains the delete document ID and revision:
+
+.. code-block:: javascript
+
+    {
+       "id" : "recipe/_design/recipes"
+       "ok" : true,
+       "rev" : "3-7a05370bff53186cb5d403f861aca154",
+    }
+
+``COPY /db/_design/design-doc``
+===============================
+
+* **Method**: ``COPY /db/_design/design-doc``
+* **Request**: None
+* **Response**: JSON of the new document and revision
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: rev
+
+    * **Description**:  Revision to copy from
+    * **Optional**: yes
+    * **Type**: string
+
+* **HTTP Headers**
+
+  * **Header**: ``Destination``
+
+    * **Description**: Destination document (and optional revision)
+    * **Optional**: no
+
+The ``COPY`` command (non-standard HTTP) copies an existing design
+document to a new or existing document.
+
+The source design document is specified on the request line, with the
+``Destination`` HTTP Header of the request specifying the target
+document.
+
+Copying a Design Document
+-------------------------
+
+To copy the latest version of a design document to a new document you
+specify the base document and target document:
+
+.. code-block:: http
+
+    COPY http://couchdb:5984/recipes/_design/recipes
+    Content-Type: application/json
+    Destination: /recipes/_design/recipelist
+
+The above request copies the design document ``recipes`` to the new
+design document ``recipelist``. The response is the ID and revision of
+the new document.
+
+.. code-block:: javascript
+
+    {
+       "id" : "recipes/_design/recipelist"
+       "rev" : "1-9c65296036141e575d32ba9c034dd3ee",
+    }
+
+.. note::
+   Copying a design document does automatically reconstruct the view
+   indexes. These will be recreated, as with other views, the first
+   time the new view is accessed.
+
+Copying from a Specific Revision
+--------------------------------
+
+To copy *from* a specific version, use the ``rev`` argument to the query
+string:
+
+.. code-block:: http
+
+    COPY http://couchdb:5984/recipes/_design/recipes?rev=1-e23b9e942c19e9fb10ff1fde2e50e0f5
+    Content-Type: application/json
+    Destination: recipes/_design/recipelist
+
+The new design document will be created using the specified revision of
+the source document.
+
+Copying to an Existing Design Document
+--------------------------------------
+
+To copy to an existing document, you must specify the current revision
+string for the target document, using the ``rev`` parameter to the
+``Destination`` HTTP Header string. For example:
+
+.. code-block:: http
+
+    COPY http://couchdb:5984/recipes/_design/recipes
+    Content-Type: application/json
+    Destination: recipes/_design/recipelist?rev=1-9c65296036141e575d32ba9c034dd3ee
+
+The return value will be the new revision of the copied document:
+
+.. code-block:: javascript
+
+    {
+       "id" : "recipes/_design/recipes"
+       "rev" : "2-55b6a1b251902a2c249b667dab1c6692",
+    }
+
+``GET /db/_design/design-doc/attachment``
+=========================================
+
+* **Method**: ``GET /db/_design/design-doc/attachment``
+* **Request**: None
+* **Response**: Returns the attachment data
+* **Admin Privileges Required**: no
+
+Returns the file attachment ``attachment`` associated with the design
+document ``/_design_/design-doc``. The raw data of the associated
+attachment is returned (just as if you were accessing a static file. The
+returned HTTP ``Content-type`` will be the same as the content type set
+when the document attachment was submitted into the database.
+
+``PUT /db/_design/design-doc/attachment``
+=========================================
+
+* **Method**: ``PUT /db/_design/design-doc/attachment``
+* **Request**: Raw document data
+* **Response**: JSON document status
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: rev
+
+    * **Description**:  Current document revision
+    * **Optional**: no
+    * **Type**: string
+
+* **HTTP Headers**
+
+  * **Header**: ``Content-Length``
+
+    * **Description**: Length (bytes) of the attachment being uploaded
+    * **Optional**: no
+
+  * **Header**: ``Content-Type``
+
+    * **Description**: MIME type for the uploaded attachment
+    * **Optional**: no
+
+  * **Header**: ``If-Match``
+
+    * **Description**: Current revision of the document for validation
+    * **Optional**: yes
+
+Upload the supplied content as an attachment to the specified design
+document (``/_design/design-doc``). The ``attachment`` name provided
+must be a URL encoded string. You must also supply either the ``rev``
+query argument or the ``If-Match`` HTTP header for validation, and the
+HTTP headers (to set the attacment content type). The content type is
+used when the attachment is requested as the corresponding content-type
+in the returned document header.
+
+For example, you could upload a simple text document using the following
+request:
+
+.. code-block:: http
+
+    PUT http://couchdb:5984/recipes/_design/recipes/view.css?rev=7-f7114d4d81124b223283f3e89eee043e
+    Content-Length: 39
+    Content-Type: text/plain
+
+    div.recipetitle {
+    font-weight: bold;
+    }
+
+Or by using the ``If-Match`` HTTP header:
+
+.. code-block:: http
+
+    PUT http://couchdb:5984/recipes/FishStew/basic
+    If-Match: 7-f7114d4d81124b223283f3e89eee043e
+    Content-Length: 39
+    Content-Type: text/plain
+
+    div.recipetitle {
+    font-weight: bold;
+    }
+
+The returned JSON contains the new document information:
+
+.. code-block:: javascript
+
+    {
+       "id" : "_design/recipes"
+       "ok" : true,
+       "rev" : "8-cb2b7d94eeac76782a02396ba70dfbf5",
+    }
+
+.. note::
+   Uploading an attachment updates the corresponding document revision.
+   Revisions are tracked for the parent document, not individual attachments.

+
+.. code-block:: http
+
+    DELETE http://couchdb:5984/recipes/_design/recipes/view.css?rev=9-3db559f13a845c7751d407404cdeaa4a
+
+The returned JSON contains the updated revision information for the
+parent document:
+
+.. code-block:: javascript
+
+    {
+       "id" : "_design/recipes"
+       "ok" : true,
+       "rev" : "10-f3b15bb408961f8dcc3d86c7d3b54c4c",

+
+Querying Views and Indexes
+--------------------------
+
+The definition of a view within a design document also creates an index
+based on the key information defined within each view. The production
+and use of the index significantly increases the speed of access and
+searching or selecting documents from the view.
+
+However, the index is not updated when new documents are added or
+modified in the database. Instead, the index is generated or updated,
+either when the view is first accessed, or when the view is accessed
+after a document has been updated. In each case, the index is updated
+before the view query is executed against the database.
+
+View indexes are updated incrementally in the following situations:
+
+-  A new document has been added to the database.
+
+-  A document has been deleted from the database.
+
+-  A document in the database has been updated.
+
+View indexes are rebuilt entirely when the view definition changes. To
+achieve this, a 'fingerprint' of the view definition is created when the
+design document is updated. If the fingerprint changes, then the view
+indexes are entirely rebuilt. This ensures that changes to the view
+definitions are reflected in the view indexes.
+
+.. note::
+   View index rebuilds occur when one view from the same the view group
+   (i.e. all the views defined within a single a design document) has
+   been determined as needing a rebuild. For example, if if you have a
+   design document with different views, and you update the database,
+   all three view indexes within the design document will be updated.
+
+Because the view is updated when it has been queried, it can result in a
+delay in returned information when the view is accessed, especially if
+there are a large number of documents in the database and the view index
+does not exist. There are a number of ways to mitigate, but not
+completely eliminate, these issues. These include:
+
+-  Create the view definition (and associated design documents) on your
+   database before allowing insertion or updates to the documents. If
+   this is allowed while the view is being accessed, the index can be
+   updated incrementally.
+
+-  Manually force a view request from the database. You can do this
+   either before users are allowed to use the view, or you can access
+   the view manually after documents are added or updated.
+
+-  Use the ``/db/_changes`` method to monitor for changes to the
+   database and then access the view to force the corresponding view
+   index to be updated. See :ref:`api-changes` for more information.
+
+-  Use a monitor with the ``update_notification`` section of the CouchDB
+   configuration file to monitor for changes to your database, and
+   trigger a view query to force the view to be updated. For more
+   information, see :ref:`update-notifications`.
+
+None of these can completely eliminate the need for the indexes to be
+rebuilt or updated when the view is accessed, but they may lessen the
+effects on end-users of the index update affecting the user experience.
+
+Another alternative is to allow users to access a 'stale' version of the
+view index, rather than forcing the index to be updated and displaying
+the updated results. Using a stale view may not return the latest
+information, but will return the results of the view query using an
+existing version of the index.
+
+For example, to access the existing stale view ``by_recipe`` in the
+``recipes`` design document:
+
+.. code-block:: text
+
+    http://couchdb:5984/recipes/_design/recipes/_view/by_recipe?stale=ok
+
+Accessing a stale view:
+
+-  Does not trigger a rebuild of the view indexes, even if there have
+   been changes since the last access.
+
+-  Returns the current version of the view index, if a current version
+   exists.
+
+-  Returns an empty result set if the given view index does exist.
+
+As an alternative, you use the ``update_after`` value to the ``stale``
+parameter. This causes the view to be returned as a stale view, but for
+the update process to be triggered after the view information has been
+returned to the client.
+
+In addition to using stale views, you can also make use of the
+``update_seq`` query argument. Using this query argument generates the
+view information including the update sequence of the database from
+which the view was generated. The returned value can be compared this to
+the current update sequence exposed in the database information
+(returned by :ref:`api-get-db`).
+
+Sorting Returned Rows
+---------------------
+
+Each element within the returned array is sorted using native UTF-8
+sorting according to the contents of the key portion of the emitted
+content. The basic order of output is as follows:
+
+-  ``null``
+
+-  ``false``
+
+-  ``true``
+
+-  Numbers
+
+-  Text (case sensitive, lowercase first)
+
+-  Arrays (according to the values of each element, in order)
+
+-  Objects (according to the values of keys, in key order)
+
+You can reverse the order of the returned view information by using the
+``descending`` query value set to true. For example, Retrieving the list
+of recipes using the ``by_title`` (limited to 5 records) view:
+
+.. code-block:: javascript
+
+    {
+       "offset" : 0,

+Requesting the same in descending order will reverse the entire view
+content. For example the request
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/_design/recipes/_view/by_title?limit=5&descending=true
+    Accept: application/json
+    Content-Type: application/json
+
+Returns the last 5 records from the view:
+
+.. code-block:: javascript
+
+    {
+       "offset" : 0,
+       "rows" : [
+          {

+             ]
+          },
+          {

+                "Zingy lemon tart"
+             ]
+          },

+             "key" : "Zesty seafood avocado",
+             "value" : [
+                null,
+                "Zesty seafood avocado"
+             ]
+          },
+          {

+             "value" : [
+                null,
+                "Zabaglione"
+             ]
+          },
+          {
+             "id" : "Yogurtraita",
+             "key" : "Yogurt raita",
+             "value" : [
+                null,
+                "Yogurt raita"
+             ]
+          }
+       ],
+       "total_rows" : 2667
+    }
+
+The sorting direction is applied before the filtering applied using the
+``startkey`` and ``endkey`` query arguments. For example the following
+query:
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/_design/recipes/_view/by_ingredient?startkey=%22carrots%22&endkey=%22egg%22
+    Accept: application/json
+    Content-Type: application/json
+
+Will operate correctly when listing all the matching entries between
+“carrots” and ``egg``. If the order of output is reversed with the
+``descending`` query argument, the view request will return no entries:
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/_design/recipes/_view/by_ingredient?descending=true&startkey=%22carrots%22&endkey=%22egg%22
+    Accept: application/json
+    Content-Type: application/json
+
+The returned result is empty:
+
+.. code-block:: javascript
+
+    {
+       "total_rows" : 26453,
+       "rows" : [],
+       "offset" : 21882
+    }
+
+The results will be empty because the entries in the view are reversed
+before the key filter is applied, and therefore the ``endkey`` of “egg”
+will be seen before the ``startkey`` of “carrots”, resulting in an empty
+list.
+
+Instead, you should reverse the values supplied to the ``startkey`` and
+``endkey`` parameters to match the descending sorting applied to the
+keys. Changing the previous example to:
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/_design/recipes/_view/by_ingredient?descending=true&startkey=%22egg%22&endkey=%22carrots%22
+    Accept: application/json
+    Content-Type: application/json

+
+Executes the specified ``view-name`` from the specified ``design-doc``
+design document. Unlike the ``GET`` method for accessing views, the
+``POST`` method supports the specification of explicit keys to be
+retrieved from the view results. The remainder of the ``POST`` view
+functionality is identical to the :ref:`api-get-view` API.
+
+For example, the request below will return all the recipes where the key
+for the view matches either “claret” or “clear apple cider” :
+
+.. code-block:: http
+
+    POST http://couchdb:5984/recipes/_design/recipes/_view/by_ingredient
+    Content-Type: application/json
+
+    {
+       "keys" : [
+          "claret",
+          "clear apple juice"
+       ]
+    }
+          
+
+The returned view data contains the standard view information, but only
+where the keys match.
+
+.. code-block:: javascript
+
+    {
+       "total_rows" : 26484,
+       "rows" : [
+          {
+             "value" : [
+                "Scotch collops"
+             ],
+             "id" : "Scotchcollops",
+             "key" : "claret"
+          },
+          {
+             "value" : [
+                "Stand pie"
+             ],
+             "id" : "Standpie",
+             "key" : "clear apple juice"
+          }
+       ],
+       "offset" : 6324
+    }
+
+Multi-document Fetching
+-----------------------
+
+By combining the ``POST`` method to a given view with the
+``include_docs=true`` query argument you can obtain multiple documents
+from a database. The result is more efficient than using multiple
+:ref:`api-get-doc` requests.
+
+For example, sending the following request for ingredients matching
+“claret” and “clear apple juice”:
+
+.. code-block:: http
+
+    POST http://couchdb:5984/recipes/_design/recipes/_view/by_ingredient?include_docs=true
+    Content-Type: application/json
+
+    {
+       "keys" : [
+          "claret",
+          "clear apple juice"
+       ]
+    }
+
+Returns the full document for each recipe:
+
+.. code-block:: javascript
+
+    {
+       "offset" : 6324,
+       "rows" : [

+
+``POST /db``
+============
+
+* **Method**: ``POST /db``
+* **Request**: JSON of the new document
+* **Response**: JSON with the committed document information
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: batch
+
+    * **Description**:  Allow document store request to be batched with others
+    * **Optional**: yes
+    * **Type**: string
+    * **Supported Values**: asd
+    * **ok**: Enable
+
+* **Return Codes**:
+
+  * **201**:
+    Document has been created successfully
+  * **409**:
+    Conflict - a document with the specified document ID already exists
+
+Create a new document in the specified database, using the supplied JSON
+document structure. If the JSON structure includes the ``_id`` field,
+then the document will be created with the specified document ID. If the
+``_id`` field is not specified, a new unique ID will be generated.
+
+For example, you can generate a new document with a generated UUID using
+the following request:
+
+.. code-block:: http
+
+    POST http://couchdb:5984/recipes/
+    Content-Type: application/json
+
+    {
+       "servings" : 4,
+       "subtitle" : "Delicious with fresh bread",
+       "title" : "Fish Stew"
+    }
+
+The return JSON will specify the automatically enerated ID and revision
+information:
+
+.. code-block:: javascript
+
+    {
+       "id" : "64575eef70ab90a2b8d55fc09e00440d",
+       "ok" : true,
+       "rev" : "1-9c65296036141e575d32ba9c034dd3ee"
+    }
+
+Specifying the Document ID
+--------------------------
+
+The document ID can be specified by including the ``_id`` field in the
+JSON of the submitted record. The following request will create the same
+document with the ID ``FishStew``:
+
+.. code-block:: http
+
+    POST http://couchdb:5984/recipes/
+    Content-Type: application/json
+
+    {
+       "_id" : "FishStew",
+       "servings" : 4,
+       "subtitle" : "Delicious with fresh bread",
+       "title" : "Fish Stew"
+    }
+
+The structure of the submitted document is as shown in the table below:
+
+In either case, the returned JSON will specify the document ID, revision
+ID, and status message:
+
+.. code-block:: javascript
+
+    {
+       "id" : "FishStew",
+       "ok" : true,
+       "rev" : "1-9c65296036141e575d32ba9c034dd3ee"
+    }
+        
+
+.. _api-batch-writes:
+
+Batch Mode Writes
+-----------------
+
+You can write documents to the database at a higher rate by using the
+batch option. This collects document writes together in memory (on a
+user-by-user basis) before they are committed to disk. This increases
+the risk of the documents not being stored in the event of a failure,
+since the documents are not written to disk immediately.
+
+To use the batched mode, append the ``batch=ok`` query argument to the
+URL of the ``PUT`` or ``POST`` request. The CouchDB server will respond
+with a 202 HTTP response code immediately.
+
+Including Attachments
+---------------------
+
+You can include one or more attachments with a given document by
+incorporating the attachment information within the JSON of the
+document. This provides a simpler alternative to loading documents with
+attachments than making a separate call (see :ref:`api-put-attachment`).
+
+* **_id** (optional): Document ID
+* **_rev** (optional): Revision ID (when updating an existing document)
+* **_attachments** (optional): Document Attachment
+
+  * **filename**: Attachment information
+
+    * **content_type**: MIME Content type string
+    * **data**: File attachment content, Base64 encoded
+
+The ``filename`` will be the attachment name. For example, when sending
+the JSON structure below:
+
+.. code-block:: javascript
+
+    {
+       "_id" : "FishStew",
+       "servings" : 4,
+       "subtitle" : "Delicious with fresh bread",
+       "title" : "Fish Stew"
+       "_attachments" : {
+          "styling.css" : {
+             "content-type" : "text/css",
+             "data" : "cCB7IGZvbnQtc2l6ZTogMTJwdDsgfQo=",
+             },
+       },
+    }
+        
+
+The attachment ``styling.css`` can be accessed using
+``/recipes/FishStew/styling.css``. For more information on attachments,
+see :ref:`api-get-attachment`.
+
+The document data embedded in to the structure must be encoded using
+base64.
+
+.. _api-get-doc:
+
+``GET /db/doc``
+===============
+
+* **Method**: ``GET /db/doc``
+* **Request**: None
+* **Response**: Returns the JSON for the document
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: conflicts
+
+    * **Description**: Returns the conflict tree for the document.
+    * **Optional**: yes
+    * **Type**: boolean
+    * **Default**: false
+    * **Supported Values**:
+
+      * **true**: Includes the revisions
+
+  * **Argument**: rev
+
+    * **Description**: Specify the revision to return
+    * **Optional**: yes
+    * **Type**: string
+    * **Supported Values**:
+
+      * **true**: Includes the revisions
+
+  * **Argument**: revs
+
+    * **Description**:  Return a list of the revisions for the document
+    * **Optional**: yes
+    * **Type**: boolean
+
+  * **Argument**: revs_info
+
+    * **Description**: Return a list of detailed revision information for the
+      document
+    * **Optional**: yes
+    * **Type**: boolean
+    * **Supported Values**:
+
+      * **true**: Includes the revisions
+
+* **Return Codes**:
+
+  * **200**:
+    Document retrieved
+  * **400**:
+    The format of the request or revision was invalid
+  * **404**:
+    The specified document or revision cannot be found, or has been deleted
+  * **409**:
+    Conflict - a document with the specified document ID already exists
+
+Returns the specified ``doc`` from the specified ``db``. For example, to
+retrieve the document with the id ``FishStew`` you would send the
+following request:
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/FishStew
+    Content-Type: application/json
+    Accept: application/json
+
+The returned JSON is the JSON of the document, including the document ID
+and revision number:
+
+.. code-block:: javascript
+
+    {
+       "_id" : "FishStew",
+       "_rev" : "3-a1a9b39ee3cc39181b796a69cb48521c",
+       "servings" : 4,
+       "subtitle" : "Delicious with a green salad",
+       "title" : "Irish Fish Stew"
+    }
+        
+
+Unless you request a specific revision, the latest revision of the
+document will always be returned.
+
+Attachments
+-----------
+
+If the document includes attachments, then the returned structure will
+contain a summary of the attachments associated with the document, but
+not the attachment data itself.
+
+The JSON for the returned document will include the ``_attachments``
+field, with one or more attachment definitions. For example:
+
+.. code-block:: javascript
+
+    {
+       "_id" : "FishStew",
+       "servings" : 4,
+       "subtitle" : "Delicious with fresh bread",
+       "title" : "Fish Stew"
+       "_attachments" : {
+          "styling.css" : {
+             "stub" : true,
+             "content-type" : "text/css",
+             "length" : 783426,
+             },
+       },
+    }
+
+The format of the returned JSON is shown in the table below:
+
+* **_id** (optional): Document ID
+* **_rev** (optional): Revision ID (when updating an existing document)
+* **_attachments** (optional): Document Attachment
+
+  * **filename**: Attachment information
+
+    * **content_type**: MIME Content type string
+    * **length**: Length (bytes) of the attachment data
+    * **revpos**: Revision where this attachment exists
+    * **stub**: Indicates whether the attachment is a stub
+
+Getting a List of Revisions
+---------------------------
+
+You can obtain a list of the revisions for a given document by adding
+the ``revs=true`` parameter to the request URL. For example:
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/FishStew?revs=true
+    Accept: application/json
+
+The returned JSON structure includes the original document, including a
+``_revisions`` structure that includes the revision information:
+
+.. code-block:: javascript
+
+    {
+       "servings" : 4,
+       "subtitle" : "Delicious with a green salad",
+       "_id" : "FishStew",
+       "title" : "Irish Fish Stew",
+       "_revisions" : {
+          "ids" : [
+             "a1a9b39ee3cc39181b796a69cb48521c",
+             "7c4740b4dcf26683e941d6641c00c39d",
+             "9c65296036141e575d32ba9c034dd3ee"

+    }
+
+* **_id** (optional): Document ID
+* **_rev** (optional): Revision ID (when updating an existing document)
+* **_revisions**: CouchDB Document Revisions
+
+  * **ids** [array]: Array of valid revision IDs, in reverse order
+    (latest first)
+  * **start**: Prefix number for the latest revision
+
+Obtaining an Extended Revision History
+--------------------------------------
+
+You can get additional information about the revisions for a given
+document by supplying the ``revs_info`` argument to the query:
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/FishStew?revs_info=true
+    Accept: application/json
+
+This returns extended revision information, including the availability
+and status of each revision:
+
+.. code-block:: javascript
+
+    {
+       "servings" : 4,
+       "subtitle" : "Delicious with a green salad",
+       "_id" : "FishStew",
+       "_revs_info" : [
+          {
+             "status" : "available",
+             "rev" : "3-a1a9b39ee3cc39181b796a69cb48521c"
+          },
+          {
+             "status" : "available",
+             "rev" : "2-7c4740b4dcf26683e941d6641c00c39d"
+          },
+          {
+             "status" : "available",
+             "rev" : "1-9c65296036141e575d32ba9c034dd3ee"
+          }
+       ],

+* **_revs_info** [array]: CouchDB Document Extended Revision Info
+
+  * **rev**: Full revision string
+  * **status**: Status of the revision
+
+Obtaining a Specific Revision
+-----------------------------
+
+To get a specific revision, use the ``rev`` argument to the request, and
+specify the full revision number:
+
+.. code-block:: http
+
+    GET http://couchdb:5984/recipes/FishStew?rev=2-7c4740b4dcf26683e941d6641c00c39d
+    Accept: application/json
+
+The specified revision of the document will be returned, including a
+``_rev`` field specifying the revision that was requested:
+
+.. code-block:: javascript
+
+    {
+       "_id" : "FishStew",
+       "_rev" : "2-7c4740b4dcf26683e941d6641c00c39d",
+       "servings" : 4,
+       "subtitle" : "Delicious with a green salad",
+       "title" : "Fish Stew"
+    }
+
+``HEAD /db/doc``
+================
+
+* **Method**: ``HEAD /db/doc``
+* **Request**: None
+* **Response**: None
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: rev
+
+    * **Description**:  Specify the revision to return
+    * **Optional**: yes
+    * **Type**: string
+
+  * **Argument**: revs
+
+    * **Description**:  Return a list of the revisions for the document
+    * **Optional**: yes
+    * **Type**: boolean
+
+  * **Argument**: revs_info
+
+    * **Description**:  Return a list of detailed revision information for the
+      document
+    * **Optional**: yes
+    * **Type**: boolean
+
+* **Return Codes**:
+
+  * **404**:
+    The specified document or revision cannot be found, or has been deleted
+
+Returns the HTTP Headers containing a minimal amount of information
+about the specified document. The method supports the same query
+arguments as the ``GET`` method, but only the header information
+(including document size, and the revision as an ETag), is returned. For
+example, a simple ``HEAD`` request:
+
+.. code-block:: http
+
+    HEAD http://couchdb:5984/recipes/FishStew
+    Content-Type: application/json
+        
+
+Returns the following HTTP Headers:
+
+.. code-block:: javascript
+
+    HTTP/1.1 200 OK
+    Server: CouchDB/1.0.1 (Erlang OTP/R13B)
+    Etag: "7-a19a1a5ecd946dad70e85233ba039ab2"
+    Date: Fri, 05 Nov 2010 14:54:43 GMT
+    Content-Type: text/plain;charset=utf-8
+    Content-Length: 136
+    Cache-Control: must-revalidate
+
+The ``Etag`` header shows the current revision for the requested
+document, and the ``Content-Length`` specifies the length of the data,
+if the document were requested in full.
+
+Adding any of the query arguments (as supported by ```GET```_ method),
+then the resulting HTTP Headers will correspond to what would be
+returned. Note that the current revision is not returned when the
+``refs_info`` argument is used. For example:
+
+.. code-block:: http
+
+    HTTP/1.1 200 OK
+    Server: CouchDB/1.0.1 (Erlang OTP/R13B)
+    Date: Fri, 05 Nov 2010 14:57:16 GMT
+    Content-Type: text/plain;charset=utf-8
+    Content-Length: 609
+    Cache-Control: must-revalidate
+
+.. _api-put-doc:
+
+``PUT /db/doc``
+===============
+
+* **Method**: ``PUT /db/doc``
+* **Request**: JSON of the new document, or updated version of the existed
+  document
+* **Response**: JSON of the document ID and revision
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: batch
+
+    * **Description**:  Allow document store request to be batched with others
+    * **Optional**: yes
+    * **Type**: string
+    * **Supported Values**:
+
+      * **ok**: Enable
+
+* **HTTP Headers**
+
+  * **Header**: ``If-Match``
+
+    * **Description**: Current revision of the document for validation
+    * **Optional**: yes
+
+* **Return Codes**:
+
+  * **201**:
+    Document has been created successfully
+  * **202**:
+    Document accepted for writing (batch mode)
+
+
+The ``PUT`` method creates a new named document, or creates a new
+revision of the existing document. Unlike the ``POST`` method, you
+must specify the document ID in the request URL.
+
+For example, to create the document ``FishStew``, you would send the
+following request:
+
+.. code-block:: http
+
+    PUT http://couchdb:5984/recipes/FishStew
+    Content-Type: application/json
+
+    {
+      "servings" : 4,
+      "subtitle" : "Delicious with fresh bread",
+      "title" : "Fish Stew"
+    }
+
+The return type is JSON of the status, document ID,and revision number:
+
+.. code-block:: javascript
+
+    {
+       "id" : "FishStew",
+       "ok" : true,
+       "rev" : "1-9c65296036141e575d32ba9c034dd3ee"
+    }
+
+Updating an Existing Document
+-----------------------------
+
+To update an existing document you must specify the current revision
+number within the ``_rev`` parameter. For example:
+
+.. code-block:: http
+
+    PUT http://couchdb:5984/recipes/FishStew
+    Content-Type: application/json
+
+    {
+      "_rev" : "1-9c65296036141e575d32ba9c034dd3ee",
+      "servings" : 4,
+      "subtitle" : "Delicious with fresh salad",
+      "title" : "Fish Stew"
+    }
+
+Alternatively, you can supply the current revision number in the
+``If-Match`` HTTP header of the request. For example:
+
+.. code-block:: http
+
+    PUT http://couchdb:5984/recipes/FishStew
+    If-Match: 2-d953b18035b76f2a5b1d1d93f25d3aea
+    Content-Type: application/json
+
+    {
+       "servings" : 4,
+       "subtitle" : "Delicious with fresh salad",
+       "title" : "Fish Stew"
+    }
+
+The JSON returned will include the updated revision number:
+
+.. code-block:: javascript
+
+    {
+       "id" : "FishStew99",
+       "ok" : true,
+       "rev" : "2-d953b18035b76f2a5b1d1d93f25d3aea"
+    }
+
+For information on batched writes, which can provide improved
+performance, see :ref:`api-batch-writes`.
+
+.. _api-del-doc:
+
+``DELETE /db/doc``
+==================
+
+* **Method**: ``DELETE /db/doc``
+* **Request**: None
+* **Response**: JSON of the deleted revision
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: rev
+

+
+* **HTTP Headers**
+
+  * **Header**: ``If-Match``
+
+    * **Description**: Current revision of the document for validation
+    * **Optional**: yes
+
+* **Return Codes**:
+
+  * **409**:
+    Revision is missing, invalid or not the latest
+
+Deletes the specified document from the database. You must supply the
+current (latest) revision, either by using the ``rev`` parameter to
+specify the revision:
+
+.. code-block:: http
+
+    DELETE http://couchdb:5984/recipes/FishStew?rev=3-a1a9b39ee3cc39181b796a69cb48521c
+    Content-Type: application/json
+
+Alternatively, you can use ETags with the ``If-Match`` field:
+
+.. code-block:: http
+
+    DELETE http://couchdb:5984/recipes/FishStew
+    If-Match: 3-a1a9b39ee3cc39181b796a69cb48521c
+    Content-Type: application/json
+        
+
+The returned JSON contains the document ID, revision and status:
+
+.. code-block:: javascript
+
+    {
+       "id" : "FishStew",
+       "ok" : true,
+       "rev" : "4-2719fd41187c60762ff584761b714cfb"
+    }
+
+.. note:: Note that deletion of a record increments the revision number. The
+   use of a revision for deletion of the record allows replication of
+   the database to correctly track the deletion in synchronized copies.
+
+.. _api-copy-doc:
+
+``COPY /db/doc``
+================
+
+* **Method**: ``COPY /db/doc``
+* **Request**: None
+* **Response**: JSON of the new document and revision
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: rev
+
+    * **Description**:  Revision to copy from
+    * **Optional**: yes
+    * **Type**: string
+
+* **HTTP Headers**
+
+  * **Header**: ``Destination``
+
+    * **Description**: Destination document (and optional revision)
+    * **Optional**: no
+
+* **Return Codes**:
+
+  * **201**:
+    Document has been copied and created successfully
+  * **409**:
+    Revision is missing, invalid or not the latest
+
+The ``COPY`` command (which is non-standard HTTP) copies an existing
+document to a new or existing document.
+
+The source document is specified on the request line, with the
+``Destination`` HTTP Header of the request specifying the target
+document.
+
+Copying a Document
+------------------
+
+You can copy the latest version of a document to a new document by
+specifying the current document and target document:
+
+.. code-block:: http
+
+    COPY http://couchdb:5984/recipes/FishStew
+    Content-Type: application/json
+    Destination: IrishFishStew
+
+The above request copies the document ``FishStew`` to the new document
+``IrishFishStew``. The response is the ID and revision of the new
+document.
+
+.. code-block:: javascript
+
+    {
+       "id" : "IrishFishStew",
+       "rev" : "1-9c65296036141e575d32ba9c034dd3ee"
+    }
+
+Copying from a Specific Revision
+--------------------------------
+
+To copy *from* a specific version, use the ``rev`` argument to the query
+string:
+
+.. code-block:: http
+
+    COPY http://couchdb:5984/recipes/FishStew?rev=5-acfd32d233f07cea4b4f37daaacc0082
+    Content-Type: application/json
+    Destination: IrishFishStew
+
+The new document will be created using the information in the specified
+revision of the source document.
+
+Copying to an Existing Document
+-------------------------------
+
+To copy to an existing document, you must specify the current revision
+string for the target document, using the ``rev`` parameter to the
+``Destination`` HTTP Header string. For example:
+
+.. code-block:: http
+
+    COPY http://couchdb:5984/recipes/FishStew
+    Content-Type: application/json
+    Destination: IrishFishStew?rev=1-9c65296036141e575d32ba9c034dd3ee
+
+The return value will be the new revision of the copied document:
+
+.. code-block:: javascript
+
+    {
+       "id" : "IrishFishStew",
+       "rev" : "2-55b6a1b251902a2c249b667dab1c6692"
+    }
+
+.. _api-get-attachment:
+
+``GET /db/doc/attachment``
+==========================
+
+* **Method**: ``GET /db/doc/attachment``
+* **Request**: None
+* **Response**: Returns the attachment data
+* **Admin Privileges Required**: no
+
+Returns the file attachment ``attachment`` associated with the document
+``doc``. The raw data of the associated attachment is returned (just as
+if you were accessing a static file. The returned HTTP ``Content-type``
+will be the same as the content type set when the document attachment
+was submitted into the database.
+
+.. _api-put-attachment:
+
+``PUT /db/doc/attachment``
+==========================
+
+* **Method**: ``PUT /db/doc/attachment``
+* **Request**: Raw document data
+* **Response**: JSON document status
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: rev
+
+    * **Description**:  Current document revision
+    * **Optional**: no
+    * **Type**: string
+
+* **HTTP Headers**
+
+  * **Header**: ``Content-Length``
+
+    * **Description**: Length (bytes) of the attachment being uploaded
+    * **Optional**: no
+
+  * **Header**: ``Content-Type``
+
+    * **Description**: MIME type for the uploaded attachment
+    * **Optional**: no
+
+  * **Header**: ``If-Match``
+
+    * **Description**: Current revision of the document for validation
+    * **Optional**: yes
+
+* **Return Codes**:
+
+  * **201**:
+    Attachment has been accepted
+
+Upload the supplied content as an attachment to the specified document
+(``doc``). The ``attachment`` name provided must be a URL encoded
+string. You must also supply either the ``rev`` query argument or the
+``If-Match`` HTTP header for validation, and the HTTP headers (to set
+the attachment content type). The content type is used when the
+attachment is requested as the corresponding content-type in the
+returned document header.
+
+For example, you could upload a simple text document using the following
+request:
+
+.. code-block:: http
+
+    PUT http://couchdb:5984/recipes/FishStew/basic?rev=8-a94cb7e50ded1e06f943be5bfbddf8ca
+    Content-Length: 10
+    Content-Type: text/plain
+
+    Roast it
+
+Or by using the ``If-Match`` HTTP header:
+
+.. code-block:: http
+
+    PUT http://couchdb:5984/recipes/FishStew/basic
+    If-Match: 8-a94cb7e50ded1e06f943be5bfbddf8ca
+    Content-Length: 10
+    Content-Type: text/plain
+
+    Roast it
+
+The returned JSON contains the new document information:
+
+.. code-block:: javascript
+
+    {
+       "id" : "FishStew",
+       "ok" : true,
+       "rev" : "9-247bb19a41bfd9bfdaf5ee6e2e05be74"
+    }
+
+.. note:: Uploading an attachment updates the corresponding document revision.
+   Revisions are tracked for the parent document, not individual
+   attachments.
+
+Updating an Existing Attachment
+-------------------------------
+
+Uploading an attachment using an existing attachment name will update
+the corresponding stored content of the database. Since you must supply
+the revision information to add an attachment to a document, this serves
+as validation to update the existing attachment.
+
+``DELETE /db/doc/attachment``
+=============================
+
+* **Method**: ``DELETE /db/doc/attachment``
+* **Request**: None
+* **Response**: JSON status
+* **Admin Privileges Required**: no
+* **Query Arguments**:
+
+  * **Argument**: rev
+
+    * **Description**:  Current document revision
+    * **Optional**: no
+    * **Type**: string
+
+* **HTTP Headers**
+
+  * **Header**: ``If-Match``
+
+    * **Description**: Current revision of the document for validation
+    * **Optional**: yes
+
+* **Return Codes**:
+
+  * **200**:
+    Attachment deleted successfully
+  * **409**:
+    Supplied revision is incorrect or missing
+
+Deletes the attachment ``attachment`` to the specified ``doc``. You must
+supply the ``rev`` argument with the current revision to delete the
+attachment.
+
+For example to delete the attachment ``basic`` from the recipe
+``FishStew``:
+
+.. code-block:: http
+
+    DELETE http://couchdb:5984/recipes/FishStew/basic?rev=9-247bb19a41bfd9bfdaf5ee6e2e05be74
+    Content-Type: application/json
+
+        
+
+The returned JSON contains the updated revision information:
+
+.. code-block:: javascript
+
+    {
+       "id" : "FishStew",
+       "ok" : true,
+       "rev" : "10-561bf6b1e27615cee83d1f48fa65dd3e"
+    }

+Local (non-replicating) Document Methods
+========================================
+
+The Local (non-replicating) document interface allows you to create
+local documents that are not replicated to other databases. These
+documents can be used to hold configuration or other information that is
+required specifically on the local CouchDB instance.
+
+Local documents have the following limitations:
+
+-  Local documents are not replicated to other databases.
+
+-  The ID of the local document must be known for the document to
+   accessed. You cannot obtain a list of local documents from the
+   database.
+
+-  Local documents are not output by views, or the ``_all_docs`` view.
+
+Local documents can be used when you want to store configuration or
+other information for the current (local) instance of a given database.
+
+A list of the available methods and URL paths are provided below:
+
++--------+-------------------------+-------------------------------------------+
