A collection of iCalendar functions delivered as HTTP services.
iCal4j services is a collection of libraries that support deployment as a service. For example:
- iCal4j Validator
- iCal4j Serializer
- iCal4j FreeBusy
- iCal4j Connector
- iCal4j Integration
- iCal4j Query
- iCal4j User Agent
Each of these libraries are bundled with an HTTP Servlet and may be deployed either in a Web container or standalone with an embedded Jetty server. They are stateless services and containerisation will be supported to provide maximum choice in how they are deployed.
The following examples demonstrate how you might use iCal4j services to enhance an application or service.
Validate (and sanitise) incoming iCalendar data
The issue of calendar spam and other embedded nasties is becoming more of a concern for iCalendar data. The iCal4j Validator can potentially be used to screen incoming data not only for RFC compliance but also against unwanted or blacklisted content.
Generate Atom feeds from published iCalendar data
Using the iCal4j Serializer you can easily transform iCalendar data to Atom feed data, including expansion of recurring events.
Publish free/busy information for published iCalendar data
You may have a need for the iCal4j FreeBusy service to generate free/busy data from resource calendars to assist with scheduling.
Query iCalendar data using filter expressions
iCal4j includes support for a filter expression language that may be used to extract information from iCalendar object data using the iCal4j Query service.
Process iCalendar iTIP for scheduling
The iTIP specification defines how to coordinate iCalendar data between multiple calendar user agents (CUAs), and the iCal4j User Agent simplifies the processing of this data.
Send and receive iCalendar data asynchronously
Manage iCalendar data with CalDAV
