KDE PIM

KDE PIM provides a set of libraries and applications to access and manage personal information like emails, contacts, events, etc.

KDE PIM provides a set of libraries to parse and interact with various standardized PIM data formats, like RFC822 (KMime), ICAL (KCalendarCore) or VCARD (KContacts).

The backbone of the entire suite is Akonadi, the PIM storage framework. Akonadi provides unified API to access and manage any kind of PIM data regardless of the actual storage backend.

There are quite a few other libraries that provide PIM-specific widgets and utilities and can be useful for application developers who need to work with PIM data in their projects.

Please note that unless stated otherwise, none of the libraries have stable API or ABI as of now. We are trying to keep the changes small and we always announce big changes ahead on the mailing lists, but as the project evolves we might need to adjust some API here and there.
