  • Attendees will be able to identify addresses that conform and those that do not conform to current internet standards.
  • Attendees will be able to identify standards and features that should be included in Requests for Proposals (RFPs) or Requests for Quotes (RFQs), or that should be evaluated before purchase of software for use on the Web.

Attendees of this tutorial will learn about the architecture of the Web with respect to domain names and URIs, and recent proposals and recommendations for the use of non-English characters within Web addresses.

The paper will provide the general concepts behind addresses, how Unicode fits in, and the current state of the art.

Here is a list of example international domain names used in this presentation.
