Hi All,

I'm currently in the process of writing an offline webapp using all the html5 goodies for offline support. However I'm starting now to think about writing the sync module that will ensure that any offline data gets sent to the server and server data back to the client. Now I'm sure this has been done before, I mean its a pretty classic design issue that affects mobile devices and a plethora of other things. So I'm wondering can anyone point me to some good design resources for this kind of thing?

Now I really do not need to be too sophisticated with this, I mean I'm not handling multiple users accessing the same data and I'm happy not to merge conflicts (just take the latest) but still I would like a design that will allow me those options in the future.

Also, are there any open source projects implementing this type of thing? I'm not above ripping off someone else's code (if license allows) and I'm happy to port.

Thanks all

Guido
