Gxs (Transfer)
Service type: none.

| Item | Subtype | Purpose |
|---|---|---|
| GxsSyncGroupRequestItem | 1 | Requests a GxsSyncGroupItem. Sent every minute. |
| GxsSyncGroupItem | 2 | Contains a group id which needs to be transferred. Is typically sent within a list of many, in a transaction. |
| GxsSyncGroupStatsItem | 3 | Requests or contains statistics about a group (number of posts and last timestamp). |
| GxsTransferGroupItem | 4 | Contains the Gxs group data. |
| GxsSyncMessageItem | 8 | XXX |
| GxsSyncMessageRequestItem | 16 | Requests a GxsSyncMessageItem. Sent for every subscribed group. |
| GxsTransactionItem | 64 | Controls transactions which is a way to send a collection of items. |
The transfer of data is done using transactions. All items, except GxsSyncGroupRequestItem are done within transactions.
Each minute, Heike asks Juergen if it has new groups by sending a GxsSyncGroupRequestItem containing the last syncing time.
Juergen checks its list of subscribed groups and sends the ids of all of them that have been updated since that last time in a GROUP_LIST_RESPONSE transaction with many GxsSyncGroupItems.
Heike checks against all the groups she already has and requests those that are more recent on Juergen's end by sending a GROUP_LIST_REQUEST transaction with many GxsSyncGroupItems.
Juergen sends back all the groups requested by Heike that is has by doing a transfer transaction.
