After upgrading to KDE 4.7.90 (4.8.0 beta2) I've noticed a massive loss of semantic data in my Nepomuk database (restored it from backup to reproduce it). After some investigation Nepomuk developer vHanda pointed out, that we need to update the minimum dependencies for Nepomuk in KDE 4.8. Nepomuk in 4.8 needs to depend on: >=dev-libs/shared-desktop-ontologies-0.8.1 >=dev-libs/soprano-2.7.3 >=app-misc/strigi-0.7.7 Strigi is a little special here, as 0.7.7 is only tagged in upstream git so far, but no official tarball was released yet (I've asked Jos van den Oever, the Strigi maintainer, to create one). The current Strigi 0.7.6 in Gentoo also uses a custom tarball built by 'dilfridge', so the same could be probably done for 0.7.7. The dependency could be simply set to >app-misc/strigi-0.7.6 This way, strigi-9999 will be pulled in until 0.7.7 is available. Reproducible: Always Steps to Reproduce: 1. Upgrade KDE from 4.7.x to 4.8.x 2. Lose Nepomuk data 3. Find out why :) Expected Results: I'd expect to not lose any Nepomuk data when upgrading KDE
Thanks for reporting and to point that out.
