  2. What is UDDI? • UDDI: Universal Description, Discovery, and Integration • A specification for creating a registry service that catalogs organizations and their Web services • An implementation of the UDDI specification is called a UDDI registry 168493: XML and Web Services (II/2546)

  3. What is UDDI? • You can search a UDDI registry for specific kinds of companies or Web services • You can also register your own business and Web services in a UDDI registry • A UDDI registry is like an electronic “yellow Pages” that businesses xan search to find other organizations, and specify types of Web services 168493: XML and Web Services (II/2546)

  4. Public and Private UDDI Registries • A UDDI registry can be operated in two modes: public mode and private mode • A public UDDI registry is available for everyone to publish/query the business and service information on the Internet 168493: XML and Web Services (II/2546)

  5. A Public UDDI Registry • A public UDDI registry can be a logical single system built upon multiple UDDI registry nodes that their data synchronized through replication • Such global grouping of UDDI registry nodes is known as a UDDI Business Registry, or UBR 168493: XML and Web Services (II/2546)

  6. A Public UDDI Registry • Content can be added into a UDDI Business Registry (UBR) from any node • However, content can be modified or deleted only at a node at which it was inserted 168493: XML and Web Services (II/2546)

  7. A Private UDDI Registry • A private UDDI registry is operated by a single organization or a group of collaborating organizations to share the information that would be available only to the participating bodies • Private UDDI registries can impose additional security controls to prevent access by unauthorized users 168493: XML and Web Services (II/2546)

  8. A UDDI registry • A UDDI registry is itself a Web service • A Web service consumer queries the UDDI registry using the SOAP API defined by the UDDI specification • The UDDI specification publishes a WSDL description of the UDDI registry service 168493: XML and Web Services (II/2546)

  9. Interacting with a UDDI Registry • Typically, vendors implementing a UDDI registry provide two ways of interacting with a UDDI Registry Service • A GUI, for interacting with a UDDI registry • A programming interface for communicating with the UDDI registry 168493: XML and Web Services (II/2546)
