DeepaMehta 4
============

DeepaMehta 4 is a platform for collaboration and knowledge management. The vision of DeepaMehta is a Post-Desktop Metaphor user interface that abolishes applications, windows, files, and folders in favor of stable personal views of contextual content. The goal of DeepaMehta is to provide knowledge workers of all kind a cognitive adequate work environment, right after your desktop computer or laptop has booted up.

Technically DeepaMehta 4 is made of  
Server-side: Java, Neo4j, Lucene, Apache Felix (OSGi), Jetty, Jersey, Thymeleaf (optional), Neo4j Spatial (optional), Jetty WebSocket (optional), Karaf (optional), Pax Web (optional).  
Client-side: Javascript, jQuery, jQuery-UI, HTML5 Canvas, CKEditor, OpenLayers (optional), D3.js (optional).

DeepaMehta 4 is a rewrite of DeepaMehta 2.  
(DeepaMehta 3 was a research & development effort.)

**+++DISCLAIMER+++**  
DeepaMehta is under heavy development. While you can do productive work with it, DeepaMehta does not meet professional standards yet. At least there are lacks in a) security, b) robustness, and c) usability. Do not put sensitive data in DeepaMehta, in particular when you setup DeepaMehta for network access. Be aware that data loss may occur when you use DeepaMehta improperly. The DeepaMehta developers assume no liability for lost or compromised data. Please keep this in mind when using this software.


---

To install and use DeepaMehta follow 5 mandatory steps:


1. Check requirements
---------------------

* **Java 1.6** (or newer).

  To find out whether Java is already installed on your computer go to a terminal window and type `java -version`.
  For more information about Java go to <http://www.java.com>.

  Note: you do *not* need a Java plugin for your browser. DeepaMehta uses Java only at its backend.

* A **webbrowser**.

  DeepaMehta works fine at least with Firefox, Google Chrome, or Safari 5 (or newer).  
  Doesn't work with IE8. Possibly works with IE9 or IE10 (not tested).


2. Download
-----------

<http://download.deepamehta.de/deepamehta-4.8.6.zip> (7.2 MB)


3. Install
----------

Unzip the downloaded file. A folder `deepamehta-4.8.6` is created.  
You can move that folder to any place you want.

Update note: if you want update an existing DeepaMehta installation continue with "Updating DeepaMehta" now (see below).


4. Start
--------

Open the `deepamehta-4.8.6` folder and use the respective starter script for your platform:

    deepamehta-linux.sh         # choose "Run in terminal"
    deepamehta-macosx.command   # double-click it
    deepamehta-windows.bat      # double-click it

While DeepaMehta starts a terminal window opens and a lot of information is logged.  
Then a browser window opens and DeepaMehta is ready to use.

To open the DeepaMehta browser window manually:  
<http://localhost:8080/de.deepamehta.webclient/>

Login with `admin` and empty password. Now you're ready to create content.


5. Stop
-------

Go to the terminal window that opened while startup and press:

    Ctrl-C

This shuts down the web server and puts the database in a consistent state.  
You can now close the terminal window.


---

Auxiliary tasks follow:


Updating
--------

You can update from DeepaMehta 4.1 or newer to 4.8.6 while keeping your existing DeepaMehta content:

1. Install DeepaMehta 4.8.6 (see steps 2. and 3. above).
2. Stop your previous DeepaMehta installation if running. (Also stop DeepaMehta 4.8.6 if already started.)
3. Copy the `deepamehta-db` folder from your previous DeepaMehta installation into the `deepamehta-4.8.6` folder.
   (Replace as necessary.)
4. Proceed with "Start" (see step 4. above).

IMPORTANT: generally you're not required to install all intermediate versions. However there are certain versions that are mandatory to be installed. These versions comprise:

    DeepaMehta 4.5
    DeepaMehta 4.7

So, to update e.g. from DeepaMehta 4.3 to 4.8.6 you must install and run these versions consecutively: 4.5, 4.7, 4.8.6.

Updating from DeepaMehta 2 or 3 to DeepaMehta 4 is not supported. Even updating from 4.0.x is not supported.
The first updatable DeepaMehta version is 4.1.


Install plugins
---------------

You can extend DeepaMehta's functionality by installing plugins.  
See the list of available plugins:  
<https://www.deepamehta.de/content/download>


Reset the database
------------------

Sometimes you might want to restart DeepaMehta with a fresh database:

1. Stop DeepaMehta.
2. Delete the `deepamehta-db` folder.
3. Start DeepaMehta.

Caution: you will loose all your DeepaMehta content.


Uninstall
---------

1. Stop DeepaMehta.
2. Delete the entire `deepamehta-4.8.6` folder.

This removes DeepaMehta completely from your computer, including all your DeepaMehta content.
