The RTK consists of software and documentation. The software consists of a working Java API and Java and Perl samples that can be used to implement the EPP protocol used to communicate between the registry and the registrar. The samples illustrate how XML requests (registration events) can be assembled and forwarded to the registry for processing. The software provides the registrar with the basis for a reference implementation that conforms to the EPP. The software component of the toolkit is based on static XML requests.
The RTK will be provided to existing registrars on 18 January 2006. The Registrar Tool Kit is licensed under the GNU Lesser General Public License.
