KDE Core/Platform 11/PlatformVsFrameworks

Definition of Frameworks and Platform

In our communication we want to use Frameworks, since this communicates the modularity of our libraries better than the term "platform", which gives a more monolithic, either-or impression.

The KDE Frameworks

KDE Frameworks			KDE Look and Feel
Solution	Qt Addons
	Integration	Functional
Library with a hard dependency on a KDE Runtime component, and the KDE Runtime component itself. Examples: Akonadi, KIO	Library with optional dependency on a KDE Runtime component used only to workaround OS missing features (implementation detail). Examples: Date, Solid	Self-contained library, not using any KDE Runtime component. Example: KImap	Examples: KStandardActions, XML GUI, UI Standards
	Marketing side: actually indicate how difficult it is to deploy because of runtime dependencies

• Useful as separate library
• platform independent
• Split in functional and integration

Platform Definition

• not necessarily portable
• ...

What needs work here?

The following list gives an idea of some problems we see with splitting up our frameworks:

• 1) needs sycoca
• 2) uses mimetype/xdg
• 3) uses kded
• 4) kglobal used, but only for ref/deref (which can maybe move into Qt)
• 5) uses kglobal (in a non-trivial way)
• 6) uses kaboutdata
• 7) should be optional
• 8) duplicates functionality in Qt
• 9) should move into its own library
• 10) Make Qt only/split out KDE-specific parts
• 11) No clear picture
• 12) Should not be made public
