+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Welcome to Riak.
+
+Riak is a distributed, decentralized data storage system.
+
+Below, you will find the "quick start" directions for setting up and
+using Riak.  For more information, browse the following files:

+
+
+Quick Start
+---
+
+This section assumes that you have copy of the Riak source tree at
+$RIAK.  You should have created this by cloning a repo or expanding
+a tarball from somewhere.
+
+The quick start goes like this:
+
+1. Build Riak
+2. Start the Riak server
+3. Connect a client and store/fetch data
+
+
+1. Build Riak
+-
+Assuming you have a working Erlang installation, building Riak should
+be as simple as:
+
+$ cd $RIAK
+$ make
+
+
+2. Start the Riak server - Assuming no errors were generated in the
+build step, $RIAK/config/riak-demo.erlenv and replace all instances of
+$RIAK with the directory in which $RIAK is installed.  For example,
+change:
+
+{riak_heart_command, "(cd $RIAK; ./start-restart.sh $RIAK/config/riak-demo.erlenv)"}.
+
+to:
+
+{riak_heart_command, "(cd /usr/local/riak; ./start-restart.sh /usr/local/riak/config/riak-demo.erlenv)"}.
+
+Then start riak:
+
+$ cd $RIAK
+$ ./start-fresh.sh config/riak-demo.erlenv
+
+The server should start, then background itself, leaving you at a
+command prompt.
+
+At this point, you can use riak_demo.escript to ensure that Riak is
+functioning:
+
+$ ./riak_demo.escript config/riak-demo.erlenv
+Attempting to connect to 127.0.0.1:9000 with cookie riak_demo_cookie...
+Connected successfully
+Looking for pre-existing object at {riak_demo, "demo"}...
+  No pre-existing object found, creating new
+Storing object with new value...
+  Written successfully
+Fetching object at {riak_demo, "demo"}...
+  Fetched successfully
+  Object contained correct value
+SUCCESS
+
+If riak_demo prints no "Error: ..." messages, and instead prints
+"SUCCESS", then Riak is working.
+
+
+3. Connect a client
+-
+Assuming no errors were generated during the server start step, a
+simple client interaction will look like:
+
+$ erl -name riaktest@127.0.0.1 -pa $RIAK/ebin
+
+(riaktest@127.0.0.1)1> %% connect to Riak
+(riaktest@127.0.0.1)1> {ok, C} = riak:client_connect("127.0.0.1", 9000, riak_demo_cookie).
+{ok,{riak_client,'riakdemo@127.0.0.1',

+(riaktest@127.0.0.1)8> C:list_keys(groceries).
+{ok,["mine"]}
+a sampling of improvements on the way:
+ - more storage backends
+ - repeatable benchmarking suite
+ - OTP bootable release
+ - nicer shutdown mechanism
+ - better cleanup of node storage after handoff
+ - move bucket properties out of gossiped ring state
+    (allowing unlimited buckets)
+ - make default bucket properties configurable at application scope
+ - improved efficiency of vnode handoff and bootstrapping
+ - more explicit UTF-8 support and testing
+ - making nodes that have finished exiting a cluster more obvious
+ - better timeout management on individual nodes of map-phases
+ - revisit hibernate when more monitoring abilities are available
+ - document why vnode start is a spawn and monitor instead of ... ?
+ - remember why riak_vnode_master:vnode_del is a call instead of a cast
+ - riak.js: javascript library for jiak/jaywalker
+ - riak_mapreduce: provide a version of standard map funs that handles siblings
+   (with reconcile)
+-  better mapreduce docs
+-  good documents for riak_object and reconciliation
+-  better riak_object tests
+-  investigate use of global:trans/global:set_lock instead of mnesia locks -
+   mnesia locks use ets tables and are therefore probably less efficient.
+

client_lib/jiak.js

+// JiakClient assumes the presence of jQuery and JSON libraries
+// (or at least compatible $.ajax and JSON.stringify functions)
+//
+// Usage: instantiate a JiakClient with proper options, then use
+// the store, fetch, remove, and walk function to get access to
+// objects from Jiak.
+//
+// Examples:
+//   var Client = new JiakClient('/jiak/');
+//   Client.fetch('note', '123', function(note) {
+//      note.object.text = 'Hello World';
+//      Client.store(note);
+//   });
+//
+//   Client.store({'bucket':'note'
+//                 'object':{'text':'a new note'},
+//                 'links':[]},
+//                function(note) {
+//                  alert('new note's key: '+note.key);
+//                });
+//
+//   Client.walk(['note', '456'],
+//               [{'bucket':'person', 'tag':'author'}],
+//               function(data) {
+//                 var authors = data.results[0];

+Stickynotes is a demo Riak application.
+
+Running
+---
+
+cd $RIAK_HOME  # base of your riak installation
+./start-fresh demo/stickynotes/riak-config.erlenv
+cd demo/stickynotes
+make
+./start.sh
+
+Now point your browser at http://localhost:8000/
+
+You should see a dark grey page with a few controls
+at the top.  Start clicking!
+
+
+Structure
+---
+
+Stickynotes starts a Webmachine node, which exposes a simple
+file-serving resource, as well as jiak_resource and jaywalker_resource
+from Riak.  The files you'll find here:
+
+/
+ Makefile            - for rebuilding things
+ README              - this file
+ riak-config.erlenv  - Riak cluster configuration file for Stickynotes
+ start.sh            - start the Stickynotes application
+ start-dev.sh        - start Stickynotes with auto-module-reloading
+ deps/
+   riak              - symlink to riak for code path loading
+ priv/www/
+   index.html        - the HTML you see at /
+   css/
+     application.css - the CSS you see at /
+   images/           - all of the images
+   js/
+     application.js  - the logic running the page
+     jiak.js         - libary for querying Riak through Jiak
+     jquery*.js      - jQuery
+     json2.js        - JSON library
+ src/
+   groups.erl        - the Jiak bucket module for groups objects
+   notes.erl         - the Jiak bucket module for notes objects
+   stickynotes.app   - application configuration (this is where
+                       riak_ip, _port, _cookie are set)
+   stickynotes.erl   - top application file
+   stickynotes_app.erl - application start file
