Inherited by child packages.

Example:

Contents of package-info.java...

// XML namespaces used within this package. @RdfSchema(prefix="ab", namespaces={ @RdfNs(prefix="ab", namespaceURI="http://www.apache.org/addressBook/"), @RdfNs(prefix="per", namespaceURI="http://www.apache.org/person/"), @RdfNs(prefix="addr", namespaceURI="http://www.apache.org/address/"), @RdfNs(prefix="mail", namespaceURI="http://www.apache.org/mail/") } ) package org.apache.juneau.examples.addressbook; import org.apache.juneau.rdf.annotation.*;

Class in package using defined namespaces...

package org.apache.juneau.examples.addressbook; // Bean class, override "ab" namespace on package. @Rdf(prefix="addr") public class Address { // Bean property, use "addr" namespace on class. public int id; // Bean property, override with "mail" namespace. @Rdf(prefix="mail") public String street, city, state; }
