[Opensync-devel] SyncML plugin

[Michael B. <mic...@cm...>]

Hi,

the SyncML plugin heavily depends on libsyncml. So I think a rewrite and
the use of a different library would be a possible way. The problem is
that libsynthesis does not provide OBEX support.

I did stop my work because I cannot work on the plugin during my work
time and I have some general concerns on the design of SyncML and OpenSync.

SyncML merging will always be a problem. If a device is out of sync and
there are changed items on both sides there is always the risk of
duplicated entries. I can just note here that this behaviour is just
unacceptable for customers with many contacts and events. This leads to
our (university's) decision for Active Sync.

OpenSync introduces an additional problem for us. It syncs all devices
at once and requires a slow sync if there was a problem with just one
device. The following slow sync with an enabled merger can create a
complexity which is simply too high. Just calculate the effort for a
general merger and 5 devices with 100 items each.

So I personally prefer peer-to-peer and clear unique identifier designs
for synchronization.

I hope somebody else has enough motivation to take over the maintenance.
If you want to take over then you can expect that I am willing to help
with informations.

Best regards

Michael
