Warning
This page contains rough working notes from discussion sessions at Platform 11, the contents of which may not accurately reflect any decisions made. Please do not infer anything from these notes, official summaries of the conclusions reached will be made available for discussion as soon as possible.
Executive Summary
The following is how we talk about what we previously referred to as "the KDE Platform". The KDE Platform is now called the "KDE Frameworks", consisting of "Qt Addons" (functional and integration addons) and complete "KDE Solutions".
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 structure looks as follows:
KDE Frameworks
The KDE Frameworks provide high-level components to build applications on.
Qt Addons
KDE's Qt Addons provide functionality on top of Qt. These addons are easy to use in your application. KDE's Qt Addons provide complex functionality through an convenient, Qt-style API.
KDE's Qt Addons are liberally licensed under the LGPL.
Examples:
- The "Date & Time" Addons provide a complete and intuitive high-level API for dealing with time and all of its complexity, including timezones, holidays, different calendaring systems and more.
KDE Solutions
KDE's Solutions provide ready-made components you can use on a conceptionally high level.
Examples:
- Akonadi provides a complete solution for handling Email, Contacts, etc. Akonadi consists of all the needed components to accelerate your personal information management, boosting your business, making it easy to build god-like groupware clients.
Marketing Diagram
| 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 | Anything belonging to Functional cannot use anything coming from Integration | ||
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
