4.1. Property and relation-type URIs

In the XRD entity returned properties and related services and entities are defined by absolute URIs which correspond to the extended relation type defined in Internet-Draft draft-nottingham-http-link-header-10, Section 4.2. These URIs do NOT correspond to any real entity on the server and clients should not attempt to retrieve any data at that target.

Certain of these property URIs correspond to CalDAV preconditions. Each URL is prefixed by the CalWS relations and properties namespace http://docs.oasis-open.org/ws-calendar/ns/REST/. Those properties which correspond to CalDAV properties have the additional path element “caldav/”, for example

http://docs.oasis-open.org/ws-calendar/ns/REST/supported-calendar-data

corresponds to

CalDAV:supported-calendar-data

In addition to those CalDAV properties, the CalWS specification defines a number of other properties and link relations with the URI prefix of http://docs.oasis-open.org/ws-calendar/ns/REST.
