[Decibel] Akonadi integration use cases

[George Goldberg]

Hi all,

I'm working on the akonadi integration for decibel at the moment, and
have reached the stage where I need to decide what metadata decibel
will store along side addressbook entries in the form of
Akonadi::Attributes. I've found this to be just too complicated to
"sit down and code", so I am writing some usecases which I will use to
design it. The main concern for these usecases is "what is decibel
allowed to do to the user's contacts in akonadi?". Please do add any
more usecases you can think of, as I will make my design for the data
stored based on these, and I don't want to miss out any functionality
that should be there. This area is very important to get right
otherwise we will have a lot of unhappy users!

1) Adam has two address-books. One contains his personal contacts, and
the other contains his work contacts. Both address-books are cached in
Akonadi. Adam is going to use decibel for instant messaging. Many of
his personal contacts have IM addresses on file in his address book
already. When he adds a new contact with an IM address to his personal
address book, he wants it to be added to his IM account's server-side
contact list automatically, as he likes to keep in touch with his
personal friends by IM. However, he has a habbit of setting his
presence message to say rude things about his co-workers, and so it is
very important that his work contacts are not in his IM server-side
friends list. Due to the fact his work contacts are stored on an LDAP
server, other users of that server have added IM addresses to some of
the contacts, so he needs a way to tell decibel not to add contacts
from his work address-book to his IM server-side friends lists.

2) Ben has one Address Book with his friends and family in it. He
likes to keep in touch with them by IM, and expects that when he adds
a new contact with an MSN Messenger address, that contact will be
automatically added to his MSN server-side buddies list. However,
there are one or two people in his address book, whose IM addresses he
has, but he doesn't feel he knows them well enough to add them as IM
buddies, so he wants to exclude them from getting added to his IM
buddy list by decibel.

3) Cathy often adds and deletes contacts from her address book. When
she does this, she wants the altered contacts to be added and deleted
from her IM server-side buddies list as well - even if she is offline
at the time when she adds or removes the contact from her address
book.

If you can think of any other use cases, please let me know! (I'm sure
I must have missed some)
