The Technologies of an in-House Seed Handling Tool
This poster presents an in-house tool for managing collections of harvested online material and automating parts of the preservation workflow. Developed since 2018, it allows users to create thematic collections, add webpages and YouTube videos as seeds, and publish them for access at legal deposit workstations nationwide. Built in PHP with CodeIgniter and a JavaScript frontend, it supports collection management, metadata import, harvesting, and indexing. Most harvesting is manual, while simpler tasks are automated using Browsertrix, yt-dlp, and Python scripts. Collections are then indexed in SOLR and OutbackCDX and prepared for public access. Presented at the IIPC General Assembly and Web Archiving Conference held on April 20-23, 2026 in Brusells, Belgium.
