-       UDDI-Universal Description, Discovery and Integration uses standards-based services such as XML, HTTP, SOAP, TCP/IP (define above) uniform service description and service discovery protocol. Discovery services provide a consistent publishing interface and allow programmatic discovery (registration) of services.  Description services provide the means for internet registration - to be found but not advertisement or placement on search engine listings. UDDI file structures are designed using a "publish-once-read-by-many" concept.  That is, web site URL-Uniform Resource Locator can be designed using UDDI standard file structures which can be published to the UDDI server network.  The UDDI network can be accessed (discovered) by search engines, customers and other list builders in a standard published (register) format.  UDDI Registries and protocol servers with:

- White Pages - Names, Address, Contact and Vcard information

- Yellow Pages - Industry categorizations and taxonomies

- Green Pages - Technical information including internal URL file discovery structures

-       UDDI is also designed to replace the robot.txt search engine web site document structure concept. Here are some of the web site description-discovery-registry information retrieved by search engine spiders/bots and other retrieval programs.

-       Voice-driven yellow pages - SALT-Speech Applications Language Tags adds voice commands to web applications.  SALT is an extended set of markup (meta) tags based on XML-eXtensible Markup Language though compatible with HTML-Hyper-Text Markup Language and others.

-       SIP – exciting new applications
