It uses perl based cgi scripts to generate all the web pages. It gives you the choice of using a flat file database system with file locking to store the data, , or MySQL or PostgreSQL databases for calendar data. It also uses a bit of Javascript to tie things together. All you need is a unix box, perl, and a webserver to try it out.

The Retsina Semantic Web Calendar Agent provides interoperability between RDF based calendar descriptions on the web, and Personal Information Manager (PIM) Systems such as Microsoft's Outlook. Schedules and events can be described on the web in RDF, using existing ontologies such as the Hybrid iCal-like RDF Schema or the Dublin Core ontology, and linked to individual's contact information described, for example, at their home page. The Retsina Semantic Web Calendar Agent, consists of a Distributed Meeting Scheduling Engine and the RETSINA Semantic Web Calendar Parser. The agent assists in organising and scheduling meetings between several individuals, and coordinates these based on existing schedules maintained by MS Outlook.
