Here is a list of the relevant packages that already exist in CIYAM (but are not yet "blockchain" ready):

Blog
Email
Event
Forum
Group
Holding
Itinerary
Ledger
Message
Photo
Project
Schedule
Timezone
Token
Transaction
Wallet

If we wanted to create a blockchain equivalent application to CIYAM Open (http://ciyam.org/open) then we'd need the Blog, Forum, Message and Project packages.
