Work in progress: most of the infrastructure for running import via BG queues or CLI script is now in place (untested, no UI, needs tweaks & fixes)

Code structure
|
||||
==============
|
||||
|
||||
Standalone classes
|
||||
------------------
|
||||
|
||||
YammerRunner: encapsulates the iterative process of retrieving the various users,
|
||||
groups, and messages via SN_YammerClient and saving them locally
|
||||
via YammerImporter.
|
||||
|
||||
SN_YammerClient: encapsulates HTTP+OAuth interface to Yammer API, returns data
|
||||
as straight decoded JSON object trees.
|
||||
|
||||
YammerImporter: encapsulates logic to pull information from the returned API data
|
||||
and convert them to native StatusNet users, groups, and messages.
|
||||
|
||||
Web UI actions
|
||||
-------------
|
||||
|
||||
YammeradminpanelAction: web panel for site administrator to initiate and monitor
|
||||
the import process.
|
||||
|
||||
Command-line scripts
|
||||
--------------------
|
||||
|
||||
yammer-import.php: CLI script to start a Yammer import run in one go.
|
||||
|
||||
Database objects
|
||||
----------------
|
||||
|
||||
Yammer_state: data object storing YammerRunner's state between iterations.
|
||||
|
||||
Yammer_notice_stub: data object for temporary storage of fetched Yammer messages
|
||||
between fetching them (reverse chron order) and saving them
|
||||
to local messages (forward chron order).
|
||||
Yammer_user,
|
||||
Yammer_group,
|
||||
Yammer_notice: data objects mapping original Yammer item IDs to their local copies.
