you will obtain the event with a summary “foo” in the foo.EML file. The EML file is actually an RFC 2821 message with a text/calendar part. That part can be extracted and imported into SOGo easily. WebDAV is de-emphasized in Microsoft Exchange 2007, so hurry and migrate from it.
A similar approach can be used with Oracle Calendar. A demo program bundled with Oracle's SDK provides an excellent starting point for becoming familiar with the shared library named capi. With this library, you can retrieve a user's events formatted with the iCalendar standard. As with Microsoft Exchange, the migration process is simply to push all events in SOGo through WebDAV. The Oracle Calendar's only limitation is related to recurring events; even though a series of events can be identified clearly, there is no easy way to retrieve the original recurrence rule definition. This frustration surely will be attenuated by the advantages of SOGo, such as endless recurring events and a much more modern Web interface.
Standards, such as CalDAV and SyncML, finally have emerged that improve interoperability between native groupware clients and various servers. Open-source developers have proven their commitment in supporting those standards and created competitive alternatives to commercial solutions.
The Scalable OpenGroupware.org Project always has followed the same motivation—to offer an open-source, scalable groupware solution that integrates nicely with the Mozilla PIM suite, while not neglecting mobile users. This article should help you get started with SOGo, so you can test its functionalities for yourself. Join the mailing list to discuss your experience with the developers.
