Open School Admin (OSA) is a Web-based school administration system primarily focused on ease of use and access to school information. It has been in continuous use and development for the past 7 years. It manages all aspects of school administration: student enrollment, class scheduling, mark reporting, attendance, user accounts, and room booking. Through the use of various plugins, it also manages email announcements (including automated attendance notices), government reporting, dorm room management, Alumni relations, etc. It is a standalone application written using a Perl/MySQL back end. It requires a Web server (Apache/Lighttpd tested) and should run out of the box on any Unix system. While OSA itself is very mature, the installation and setup is still a young and evolving process.
SOGo is a very fast and scalable modern collaboration suite (or groupware). It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (IMAP, CalDAV, CardDAV, etc.) and thereby provides native connectivity (without plugins) to many clients such as Microsoft Outlook, Apple iCal, the iPhone, Mozilla Lightning, and a plethora of mobile devices via SyncML. It can reuse any existing email and database infrastructure, avoiding long hours of site restructuring.
