About the Project:
• Designed and developed a social-educational website for providing access to the corpus of Stalin Digital Archive to students and other interested parties (through subscriptions).
• The archive itself is a large number of XML files with data (digitized books, letters, and so on) along with the metadata and many images.
• The problem was enabling user-friendly access to all this information through the Stalin Digital Archive website. Users needed the ability to navigate, search, discuss, bookmark, and so on through all documents in the archive.
• The front end was implemented on top of PHP and Drupal CMS as a bunch of custom Drupal modules.
