-======YaMMS - Yet another Medical Messaging System======
-=====Message Transport Procedure=====
-====Message IDs and logging====
-Message ids are based on date, time and a serial number counting from 0 padded with zeros up to precisely 5 characters. Example: ''20110125125900001'' for the second id (serial number 1) generated at 2011-01-25 12:59.
-This number is converted into hex (network order/big endian) generating a string of precisely 14 characters (max length in MedCom message field)
-All messages, both received and sent, are stored in a log folder with a hex[0-2]/hex[3-4] folder structure (first three chars and then next two chars) and with the message id as the file name.
-These files are used when generating new message ids in order to guarantee uniqueness (CREATE_EXCL).
-The above example id would be encoded into: ''47720D608496E1'' and stored in the folders ''477/20''.
-A message sent one month later, ''20110225125900001'', will become ''477224A8FB7EE1'' and therefore be stored in ''477/22''.
-The folder changes roughly twice per month.
-====Receiving====
-  * Message files drop into the inbox folder from ftp in regular intervals (ex. 10 minutes).
-  * Each message file is parsed and receipts are put in the outbox.
-  * Each message file is added to an index containing message metadata (ex. read/unread).
-  * Bad messages (syntax errors, unknown types etc.) are marked as such.
-  * Control messages are used to mark uploaded messages in the outbox-waiting-confirm folder.
-====Sending====
-  * Inotify on the outbox triggers the sending event.
-  * Any newly written messages in the outbox is syntax checked and validated.
-  * Errornous messages are stalled and a message is put in the inbox that the message could not be sent.
-  * Validated messages are uploaded to the ftp server.
-  * Each uploaded file is put in a outbox-waiting-confirm folder and marked as uploaded but not confirmed.
-  * Each upload also makes a download.
-=====Http protocol (client interface)=====
-  * Get inbox contents (list of messages containing id, type and resume tupples)
-  * Move message to [trash|archive|...]
-  * (Delete message entirely?)
-  * Send [hospitalreferral|...]
-  * Mark message as [read|unread|handled|...]
-  * Get address by id.
-  * Edit address (by id).
