[Opensync-users] How to use libsyncml

[Samant M. <sam...@gm...>]

Hi,

I'm trying to write a plugin for conduit (http://www.conduit-project.org/),
a Gnome synchronisation application. The idea is that the plugin would
expose the data in a cell phone such as vcards, calendar entries, tasks and
notes (depending on what the phone supports). Conduit natively knows about
many of these data types and can handle the synchronisation in much the same
way as OpenSync.

In light of this, I've been looking at libsyncml as a way to implement this
plugin. Conduit plugins are implemented in Python, so I'm thinking of
writing sort of an API layer in C to call libsyncml and then link to this
from the Python code.

My main problem is that it's not really clear to me how best to use
libsyncml. Unfortunately I haven't found a huge amount of documentation on
how best to use the library. I'm hoping to avoid having to learn the
internals of the SyncML protocol.

My question is simply, is my plan feasible? If so, where can I find
documentation to help me out?

Thanks in advance,

Samant

Did you contact John Carr? He works on some Python or Vala stuff and
libsyncml. I started to reduce an re-write the interface because of his
comments.

The main recommendation is to only use the high level DS API. The source
code includes a tool called syncml-ds-tool which was designed as test
tool for phones and as example for the DS API. So the best way to start
learning is to look at this example.

The high level API reduces the required SyncML knowledge to a minimum
but some stuff is still required. You have to understand the difference
between slow/full and normal/incremental sync. Additionally you have to
understand a concept like sync anchors.

I hope this helps you for the first steps.

Best regards

Michael
