Executing XQuery functions
eXist provides an XQuery module called xmldb (see xmldb ). This module provides
functions that allow you to retrieve the created and last-modified timestamps of
resources, and allows you to retrieve or set the Internet media type of a resource.
Likewise, the previously mentioned Security Manager XQuery module provides func‐
tions for retrieving the permissions and changing the owner user, group, and mode
of a resource (see sm ).
Using the XML-RPC or XML:DB API
eXist's XML-RPC (see “XML-RPC API” on page 342 ) and XML:DB (see “XML:DB
Remote API” on page 349 ) APIs allow you to programmatically connect to the database
remotely (or even within an embedded JVM, if you're using XML:DB) and retrieve
and modify the permissions of a resource. The use of these APIs is discussed more
thoroughly in Chapter 13 .
Using the eXist Ant tasks
eXist provides a series of tasks that can be used with Apache Ant, the basics of which
are covered in “Using Ant with eXist” on page 381 . These tasks allow you to change
permissions ( chmod ), change ownership ( chown ), and add, edit, and remove users and
groups.
