Editing Web Services Discovery (section)

==Structure of UDDI==
A UDDI business registration consists of three components:
* White Pages — address, contact, and known identifiers;
* Yellow Pages — industrial categorizations based on standard [[Taxonomy (general)|taxonomies]];
* Green Pages — technical information about services exposed by the business.

===White Pages===
White pages give information about the business supplying the service.  This includes the name of the business and a description of the business - potentially in multiple languages.  Using this information, it is possible to find a service about which some information is already known (for example, locating a service based on the provider's name).<ref name="Taylor 2005">Taylor, Ian J.

Contact information for the business is also provided - for example the businesses address and phone number; and other information such as the Dun & Bradstreet.

===Yellow Pages===<!--[[Yellow Pages (UDDI)]] redirects here-->

Yellow pages provide a classification of the service or business, based on standard taxonomies.  These include the [[Standard Industrial Classification]] (SIC), the [[North American Industry Classification System]] (NAICS),<ref name="Taylor 2005"/> or the [[United Nations Standard Products and Services Code]] (UNSPSC) and geographic taxonomies.

Because a single business may provide a number of services, there may be several Yellow Pages (each describing a service) associated with one White Page (giving general information about the business).

===Green Pages===
Green pages are used to describe how to access a Web Service, with information on the service bindings.  Some of the information is related to the Web Service - such as the address of the service and the parameters, and references to specifications of interfaces.<ref name="Taylor 2005"/> Other information is not related directly to the Web Service - this includes e-mail, [[FTP]], [[CORBA]] and telephone details for the service.  Because a Web Service may have multiple bindings (as defined in its [[Web Services Description Language|WSDL]] description), a service may have multiple Green Pages, as each binding will need to be accessed differently.
