Overview

XMP metadata may include properties from one or more namespaces, each of which allows for the same tag name to appear in multiple places with different meanings. (For example, ns.adobe.com:filetype vs. ns.northplains.com:filetype.)

Organizations can define custom XMP namespaces in the Xinet database, outside of the two default namespaces: ns.adobe.com, and ns.northplains.com.

If a custom XMP namespace is required for your site, you can create it by configuring the xmp.conf file to include the custom namespace name and the associated URL.

This article will explain the process of creating a custom XMP namespace.

Process

1. Edit the xmp.conf file located at: /usr/etc/venture/var/xmp.conf.
2. By default the file's content should look like this:
   
   

   [XMPData]
   start_id=56
   

3. Mark the beginning of the custom namespace declaration(s) with [CustomNamespaces] in the file, as shown below:
   
   

   [XMPData]
   
   start_id=56
   
   [CustomNamespaces]

4. For each custom namespace, append one line containing the namespace name and a second line beneath it containing its URL in the file, as shown below:
   
   

   [XMPData]
   
   start_id=56
   
   [CustomNamespaces]
   
   ns_001=jarek
   
   url_001=http://jarek.net/xmlns/

5. Save the xmp.conf file.
