KDE4 on OpenBSD: Nepomuk

• Nepomuk is a metadata store

• OpenLink Virtuoso is actual storage backend

• Soprano provides so-called high-level “models”

• Strigi have been used by Nepomuk to extract metadata

• and Strigi is very buggy itself
• Nepomuk code contains auto-restarting, ever
• so latest KDE versions started to use own-developed libextractor instead
