TSUGI - A Framework for Building Interoperable Learning Tools

Tsugi is a multi-tenant scalable LTI library and tool hosting environment. It is intended to make it more tractable to implement the Application Store that we will need for the Next Generation Digital Learning Environment.

This repository is the Tsugi Administration, Management, and Developer Console. This code also implements an LTI 2.0 Provider, CASA App Store, and IMS ContentItem App store. Any Tsugi tool (including those written in Java and NodeJS) needs to have this software installed and configured as pre-requisite. Perhaps someday we will build Java and/or NodeJS versions of the console - but for now we just use the PHP console for applications written in any language.

While earlier versions of this repository included a set of modules, examples, and even exercises, as we move towards a 1.0 release of Tsugi, these elements are now moved to separate repositories (see below).

Pre-Requisites

Install GIT so that it works at the command prompt.
Install a PHP/MySQL Environment like XAMPP / MAMP following the instructions at:

http://www.wa4e.com/install.php

Installation

Check the code out from GitHub and put it in a directory where your web server can read it
```
  git clone https://github.com/tsugiproject/tsugi.git
```

Create a database and get authentication info for the database

  CREATE DATABASE tsugi DEFAULT CHARACTER SET utf8;
  GRANT ALL ON tsugi.* TO 'ltiuser'@'localhost' IDENTIFIED BY 'ltipassword';
  GRANT ALL ON tsugi.* TO 'ltiuser'@'127.0.0.1' IDENTIFIED BY 'ltipassword';

Copy the file config-dist.php to config.php and edit the file to put in the appropriate values. Make sure to change all the secrets. If you are just getting started turn on DEVELOPER mode so you can launch the tools easily. Each of the fields is documented in the config-dist.php file - here is some additional documentation on the configuration values:

http://do1.dr-chuck.com/tsugi/phpdoc/classes/Tsugi.Config.ConfigInfo.html
Go to the main page, and click on "Admin" to make all the database tables - you will need the Admin password you just put into config.php If all goes well, lots of tables should be created. You can run upgrade.php more than once - it will automatically detect that it has been run.

Adding Some Tools

If you are just exploring Tsugi, or doing a developer bootcamp, you can add some tools from some of the other repositories:

If you set the $CFG->install_path and go into the Admin interface, you can use "Manage Installed Modules" to install tools from Tsugi Tools
Tsugi Module Sample Code - These are relatively short bits of code that you can look at as you write your own Tsugi Module.
Tsugi Developer Exercises - This is a set of exercises of increasing difficulty suitable for a class or workshop. Working solutions are provided online. Source code for working solutions is only available to inctructors that contact Dr. Chuck.
Sample Tsugi Module - Copy this if you want to start a fresh Tsugi Module from scratch. If you are building a new tool from scratch, you should build it as a "Tsugi Module" following all of the Tsugi style guidance, using the Tsugi browser environment, and making full use of the Tsugi framework. This repository contains a basic "Tsugi Module" you can use as a starting point.
Sample Tsugi-Enabled Application - You can also use Tsugi as a library and add it to a few places in an existing application. This repository contains sample code showing how to use Tsugi as a library in an existing application.

Each of these repositories contain instructions on how to install, configure, and hook each of these applications into your Tsugi instance. Once you install a new module or modules, you will need to re-run the Admin / Database Upgrade process to create the new tables required by the new applications.

We have a short document on how to check out all of the above tools and set up the configuration for them.

Other Repositories

The Tsugi Administration Console and Tsugi Modules / Applications depend on two other repositories:

Tsugi PHP Library - This is the code for the Tsugi run-time used by the Tsugi administration console and Tsugi PHP Modules and Applications.
Tsugi Static Content - This repository contains JavaScript, images, and CSS files shared across the various Tsugi implementations (PHP, Java, and NodeJS). The static content is available at http://www.dr-chuck.net/tsugi-static/ - if you like you can check out your own copy of this repo locally or for your production environment and point your Tsugi config.php at your own copy of the library.

Other Languages

While the PHP Implementation of Tsugi is the most well developed, there are additional Tsugi implementations being developed:

Tsugi Java This is a reasonably complete implementation of the Tsugi run-time in Java. It shares low level IMS libraries with Sakai and is ready for production use.
Tsugi NodeJS - This is early pre-emergent code.
