The Storage
- Accessible via extended IMAP
=> high performance on data delivery
- Caches all PIM items of the resources
(depending on the policy)
- Informs the Control about changes
- Provides basic search features (IMAP)
- Delegates extended search requests to
SearchProviders
KDE Akademy 2006 – p. 8
SLIDE 9
The Resources
- Applications which synchronize data between the
Storage and an external data source (e.g. groupware server or file)
- Asynchronous communication
- Profiles for grouping Resources together
KDE Akademy 2006 – p. 9
SLIDE 10
The Control
- Starts and monitors the Storage and resource
processes
- Provides D-Bus API for managing resources and
profiles
KDE Akademy 2006 – p. 10
SLIDE 11
The SearchProviders
- External applications which process more complex
search queries
- One SearchProvider for every PIM item type
- Store search results in collections inside the Storage
KDE Akademy 2006 – p. 11
SLIDE 12
Collections
- Virtual containers inside the Storage
- Contain PIM items/references
- Root collection ’/’
- Every Resource provides at least one collection
- Easy to realize virtual folders
/ /resource1 /resource1/calendar /resource1/addressbook /resource2 /search

Current State
KDE Akademy 2006 – p. 13
SLIDE 14
Current State
- Storage
⊲ Provides all needed IMAP commands ⊲ Stores items in Collections
- Control
⊲ Lifetime management for Storage and Resources ⊲ D-Bus API nearly completed
- Resources
⊲ Simple iCalendar file ⊲ Dummy resource ’Knut’

TO DO
- Implementing SearchProviders
(mail, calendar, address book)
- Defining asynchronous client library
- Implementing full featured resources
(remote and local file)
- Writing documentation!!!

The Future
KDE Akademy 2006 – p. 17
SLIDE 18
The Future
- Goal: Components based PIM library
- Components as standalone views and editors of PIM
data
- Plasma applets for calendar and address book

We need developers!
