This site is a collection of real-world and example apps that leverage LTI. There are examples of LTI tool providers that offer a number of additional features, including padding grades back to the LMS and adding a custom button to a rich editor field.
Running the Tool
To run this tool, download the git repository, then open a console prompt in the repo directory.
First, if you don't already have Bundler installed, do that.
$ gem install bundler
You may need to run this command as root depending on your ruby configuration.
Next you'll want to install the necessary gems:
$ bundle install
After that you'll want to pre-populate your db with some known apps:
$ ruby parse_lti_examples.rb
Now, just start it up:
$ rackup config.ru
You will see some output like this:
Sinatra/1.3.1 has taken the stage on 4567 for development with backup from WEBrick
That number is the port that the tool is running on (4567 is the default).
To access the example tools and extensions, fire up the server and load the home page. Click "Coding" -> "Examples" for examples and directions on how to set them up.
