Programming UDDI

Two APIs are described by the UDDI specification: the inquiry API and the Publishing API. They are accessed using the same techniques but use different XML documents, data structures, and access points. The inquiry API locates information about a business, the services a business offers, the specifications of those services, and information about what to do in a failure situation. Any read operation from a UDDI registry uses one of the inquiry API’s messages. The inquiry API does not require authenticated access and is subsequently accessed using HTTP.

The Publishing API is used to create, store, or update information located in a UDDI registry. All functions in this API require authenticated access to a UDDI registry; the UDDI registry must have a logon identity, and the security credentials for this identity must be passed as a parameter of the XML document for each UDDI invocation. Because publishing requires authenticated access, it is accessed over HTTPS, with a different URL than the one used with the inquiry access point. Table 6-1 lists the inquiry and publishing access point URLs for some major operator nodes.
