This page is about the bookmarks system refactoring for 4.3 using Akonadi / Nepomuk. It's mostly Konqueror-centric, but we must keep in mind the bookmarks system is used by many applications. Comments and ideas are welcome.

General picture

Current state of bookmarks

• Currently provided classes : KBookmark, KBookmarkGroup, KBookmarksManager and others.
• Many apps use it : Konqueror, Konsole, Kate, Okular, ... need to keep backwards compatibility.
• Bookmarks are stored in a per-application XBEL file, parsed by KBookmarksManager.

Desired features

• Sync with online services / other sources
• Rating / tagging / other metadata
• Site snapshots storage
• Search by tag / metadata
• Full text indexing (Strigi)

Other ideas to discuss

• Only use tags instead of folders. Epiphany does this, mitigated reactions
• Merge bookmarks and history (to get history tagging / rating) : a bookmark may be a properly tagged history entry
• Ability to store a page (like the scrapbook firefox plugin)
  • I suggest to do this using Basket Note Pads http://basket.kde.org/ Zeroheure 09:01, 12 January 2009 (UTC)

Implementation

The consensus seems to be :

• Akonadi to handle storage and sync
• Nepomuk to handle tagging / metadata
• reuse and extend existing kdelibs/kio API

We need to define :

• the new properties to add to bookmarks
• what is already done and what is to implement

Potential issues

• KBookmark* extend QDom while Akonadi works by fetching individual items. Should we emulate a QDom or create new classes ? As the Akonadi implementation will still use bookmarks.xml, the two implementations may be used on the same data.
• A lot of Akonadi KDE api and agents are in kdepimlibs on which kdelibs can't depend.
