Coding Challenge 5.0 — Fall 2018

Due to an insufficient number of eligible entries received, RDE Systems has suspended Coding Challenge 5.0. All entrants will be notified via email separately. We hope to see your participation in future RDE Coding Challenges.

Thank you,
RDE Coding Challenge Team

Use the latest HTML5 technology to build a small web application that solves the following problem.

The Challenge

Create a web application which will allow a user to view an Articulate presentation from a selection of presentations. An admin interface will allow admin users to upload new presentations.

Official Contest Rules and Detailed Specifications

Please read the Official Rules and Specifications document at

Before submitting your entry, make sure you follow all of the requirements in the Official Rules and Specifications, or your entry will be disqualified.

How do we solve this?

Multiple presentation files will be provided to you. These presentations should be uploaded via the admin page and then viewed on the viewing page.


Each presentation will have a database entry with its decorative title, machine title, description, an active flag, and path to the respective Articulate module. Each module has a tincan.xml file: the machine title matches the id attribute of the activity tag with the type attribute "" minus the 'http://'' portion e.g.:

<activity id="http://test_1" type="">
In the above case, test_1 would be the machine title.

The presentation files are available for you to download in a ZIP file. You will need to download the zipped archive and extract its content inside a folder of your web application server.

Login Screen

There needs to be separate accounts in order to differentiate between user and admin workflows. You are required to implement a login page and have one user of each type.

Presentation Selection Screen

The presentation selection screen shows all active presentations in the following format:

Presentation Title

Presentation Description

Clicking anywhere on this widget will forward the user to the presentation which was selected. This is the default view for the 'regular user' user type.

Presentation Screen

This page will contain the selected presentation in an iframe and include a link to go back to the presentation selection screen.

Admin Screen

The main admin interface has a listing of all presentations in the system. The admin user will also have the option to create a new presentation, a workflow covered in the following screen:

Upload Presentation Screen

The admin user will first be required to enter the following fields:

  1. Display title.
  2. Description.

The admin user will then be able to upload a zipped Articulate module directory to the website. The zipped file will be required to have the following items:

  1. Tincan.xml
  2. Story.html & story_html5.html
  3. Story_content directory
  4. Html5 directory

Any uploads without these items should be deleted from the server and the site must display "Files missing. Upload Failed" to theuser. After a successful upload, a database record mustbe created, filling the required fields. Display a success message "File upload successful." See the Data section for more information.
