Re: [SyncEvolution] sqlite backend calendar

Hello, On Aug 23, 2011, at 20:29 , Patrick Ohly wrote: libsynthesis has a SQLite backend built-in, which can be configured in detail. Simplest form is just mapping elements of the internal field list to SQL table fields (see <map> in the SySync_config_reference.pdf), but there's support for parent/child relations (see <array>), programmatic mapping/conversion of special fields using the built-in script language (<beforewritescript>, <afterreadscript> etc.), finalisation to resolve inter-item dependencies (<finalisationscript>) at the end of sync and more. Have a look at src/sysync_SDK/configs/sunbird_client.xml for a reasonably complex SQLite based libsynthesis config file. Altough experimental, it added SyncML sync to Mozialla SunBird/Lightning (early versions only, in the meantime long outdated) without any coding except for the scripts in the config. So if your native data representation is SQLite, and you just want to sync that data via SyncML (and have the engine handle all the iCalendar/vCalendar stuff, as well as all change detection), just adding your own <datastore type="sql"> to the config could do the trick. On the other hand, the SyncEvolution architecture goes way beyond just that, for example providing other types of sync mechanisms, embedding libsynthesis in a environment which can communicate via http and OBEX/BT and much more. So it really depends what you're up to do. Best Regards, Lukas Zeller
