Okay. Just to give a bit of a context.

In libmokojournal things that are logged are called "entries". This is
what you call events. Each entry is of type "MokoJournalEntry". Entries
can be of a certain kind: voice call, sms, mms, etc. The kind of a given
entry is carried by the member MokoJournalEntry::type.

"MokoJournalEntry" carries the "general properties" (i.e properties
carried by all types of entries) like those which you have just listed.
So far, we are on track then :-).

For each type of entry though, there is a special member of
MokoJournalEntry that carries "specific properties". For instance, a
MokoJournalEntry of type VOICE_CALL_JOURNAL_ENTRY will have a specific
properties set (a C struct) of type MokoJournalVoiceCallInfo.
MokoJournalVoiceCallInfo itself carries all the specific properties
related to voice call journal entries.

What will be the type of a gps coordinate ? will it be a pair or floats
representing (longiture, latitude) ?

Could you give me the type of this as well ? Will it be a character
string for instance ?

Okay I guess this fits into a 16 bits integer.

Same assumption as above.

I guess this is what we have today in the MokoJournalEntry::type member.

Though, what is a data call exactly ? is what i call either SMS, MMS, or
EMAIL ?

What is "alternating" ?

> * line (some gsm modems have multiple lines)
Will this be an integer ID of the line ?

> * direction (in/out/)

Okay this one is obvious. Though I would put it in the "general"
properties carried by all journal entries.

Thank you,
