Moodle Accessibility File Scan Block

Moodle block to check PDFs for accessibility.

This Moodle block consists of two main functions:

• A Moodle block that displays the accessibility status of the PDF files within the course. On the Moodle course page, the block displays a summary with a link to a detailed view with all the files in the course.

Requirements

• Moodle 3.1+
• A server to process files: https://github.com/Swarthmore/filescan-server. This software can be installed on the Moodle server.

Dependencies

• php_curl extension

Installation

• Clone or download this repository into the <moodle root>/blocks directory
• Rename the directory from block-filescan to filescan
• Log into Moodle as an admin and update Moodle to add the block

Configuration

This plugin configuration requires a URL for the File Scan Server.

By default, the scheduled task is set to scan an additional set of files every 5 minutes. This can be adjusted in the Server --> Scheduled Tasks screen.

There are configurations for help links for each type of accessibility problems. These links can be set to specific URL's for remiation of the file.
