🧩 Installing Semantic MediaWiki in Docker

Add Semantic MediaWiki to Docker MediaWiki, fix version mismatches and keep it smooth.

  1. Enable Semantic MediaWiki
    In your LocalSettings.php, add:
wfLoadExtension( 'SemanticMediaWiki' );
enableSemantics( 'your_wiki_name' );

Run the update script:

php maintenance/update.php

Install Semantic MediaWiki via Composer:

composer require mediawiki/semantic-media-wiki:"^5.0.2"
  1. Update Docker for latest PHP
    After enabling Semantic MediaWiki, update Docker to use the latest PHP (see official Docker images for reference).
    Then restart services:
docker compose down
docker compose pull
docker compose up -d --build
  1. Fix common errors
  • Error: Class "SMWDIProperty" not found
    Search for references:
grep -R "SMWDIProperty" .

If found → replace with:

\SMW\DIProperty

If not found → update PageForms branch:

cd /var/www/html/w/extensions/PageForms
git pull origin REL1_41
  • Error: SMWRequestOptions mismatch
sed -i 's/new SMWRequestOptions()/new \\SMW\\RequestOptions()/g' \
extensions/PageForms/includes/PF_ValuesUtils.php \
extensions/PageForms/specials/PF_CreateTemplate.php

sed -i 's/@param SMWRequestOptions/@param \\SMW\\RequestOptions/g' \
extensions/PageForms/includes/PF_ValuesUtils.php

✅ Your Docker-based MediaWiki now has Semantic MediaWiki configured and ready.
