Domains
Windchill domains are administrative areas that are defined when your Windchill system is configured. A set of domains is established when Windchill is installed and the administrator can create additional domains if they are needed.
Windchill domains are used to provide a way of generally grouping access to objects. For example, the administrator can create an access control policy rule for a specific domain that enables all users to view all documents that are associated with the domain. Another rule could allow a select group of users to modify the content of all documents associated with the domain and a third rule could allow all team members to download the content of all documents associated with the domain.
When you create objects that are associated with a domain, you may not have the ability to pick the domain association. If you are allowed to select a domain when you create an object, work with your administrator to determine which domain to select. Unless you are directed to select a specific domain, the best practice is to allow Windchill to choose the domain for you.

Do not confuse Windchill domains with Internet domains. Internet domain names are used to allow easy access to information over the Internet.
