Great.

I downloaded and compiled.

I still get "no data sources" in the explorer and in some test code which 
would simply show the sources() list.
> SVN commit 923483 by sebas:
>
> birthday, location and photo for the akonadi dataengine contacts part
>
> In more general, the dataengine works as follows:
>
> For email:
> -----------
> - request "EmailCollections", you'll get a list of EmailCollections-<id>
>   as key and the name of the collection as value.
>   (The list of collections is loaded on demand)
>
> - Choose one of those collections by request the ID
>   (EmailCollection-<id>). The dataengine now queries Akonadi for all
>   emails in that collections and will add a new source for every email. In
>   you dataUpdated() method, you can simply check if the
>   source.startsWith("EmailCollection-") and then query the data from that
>   email.
>
> Properties you might be interested in for those email source are:
>  - QDate DateTime
>  - QString Subject
>  - QString From
>  - QString To
>  - qlonglong Id
>
> The Id can be used to query Akonadi for the body of the email. That part
> is not yet included in the Akonadi engine, but might come in the future.
>
> For Contacts:
> --------------
> - request "ContactCollections", choose one of those and request
>   "ContactCollection-<id>".
> - request one of those collections ("ContactCollection-<id>")
> - New sources for every contact in that collection will appear. You can
>   now get at the Contacts data through the following fields in that
>   particular source:
>
>  - double longitude
>  - double latitude
>  - QString Organization, Role, FullEmail, Name, Department, Emails,
>    various Phone- numbers
>
> Work to get those datasets more complete is under way. What's in should
> already provide for most of the use cases you can dream of.
