What is a domain?
Domains are subdivisions of the name space on a PURL resolver. They are very much like directories in a file system. The current implementation provides the ability to control who has write access (i.e., the ability to create PURLs, subdomains, etc.) within a domain. In the future, read access control will also be provided but for now, anybody can read (i.e., resolve) anybody else’s PURLs. There are two varieties of domains: top-level and subdomains. • Top-level domains, as their name implies, occupy the top-level of the name space on a PURL resolver. When you own a top-level domain, you own and control access to that entire subdivision of the purl resolver’s name space. • Subdomains exist within top-level domains or other subdomains to any level of nesting. You can create subdomains in any domain in which you have write privileges.
A domain is the name which uniquely identifies a person, company or organizzation on the Internet. For example, our domain is “register.it”. The domain is made up of two parts separated by a period. The first part is the real name, while the second is an extension which can indicate the type of activity or geographical area. For example: .it stands for Italy, .de for Germany, .com for commercial activities, etc.
