Moodle Quiz Archiver
This plugin creates archivable versions of quiz attempts as PDF and HTML files
for long-term storage independent of Moodle. If desired, Moodle backups (.mbz)
of both the quiz and the whole course can be included. A checksum is calculated
for every file within the archive, as well as the archive itself, to allow
verification of file integrity. Archives can optionally be cryptographically
signed by a trusted authority using the Time-Stamp Protocol (TSP).
Comprehensive archive settings allow selecting what should be included in the
generated reports on a fine-granular level (e.g., exclude example solutions,
include answer history, ...).
Generated quiz attempt reports include all elements of the test, even complex ones like MathJax formulas, STACK plots, GeoGebra applets, and other question / content types that require JavaScript processing. All PDF and HTML files are fully text-searchable, including rendered MathJax formulas. Content is saved vector based, whenever possible, to allow high-quality printing and zooming while keeping the file size down.
Quiz archives are created by an external quiz archive worker service to remove load from Moodle and to eliminate the need to install a large number of software dependencies on the webserver. It can easily be deployed using Docker.
