Using an Update Service

Content Studio only sends content items to an update service on demand. In order to force Content Studio to use an update service, you must add a vdf:updateservice element to one of the field elements in a publication's content-type resource. For example:

<field type="basic" name="postcode">
   <viz:updateservice href="update-service-uri"/>

When this field is modified by a user in Content Studio, a VDF Payload document representing the entire content item is sent to update-service-uri. update-service-uri should be a relative URI referencing a service in the local domain.

Note that although the viz:updateservice "trigger" is only added to one element, the update service is free to modify any fields in the submitted document, and Content Studio checks all fields in the returned document for vdf:annotation elements.
