UDDI, which stands for Universal Description, Discovery, and Integration, is an XML-based standard designed to describe, publish, and find web services. It serves as a distributed registry for businesses to list their web services and for other businesses to discover and interact with these services over the Internet.
Key Features of UDDI
Platform-Independent Framework: UDDI is an open, industry-wide framework that is platform-independent, allowing businesses of all types to list and discover web services regardless of the underlying technology[1][2].
Registry Structure: UDDI registries are structured similarly to a traditional telephone book, with three main categories:
White Pages: Contain basic information about businesses, such as names and contact details.
Yellow Pages: Categorize businesses based on the services they offer.
Green Pages: Provide technical details about the services, including how to invoke them[3][5].
Data Model and API: UDDI uses a specific data model to represent entities such as businesses, services, and binding templates. It also provides a set of APIs for querying and publishing information to the registry. These APIs facilitate the discovery and interaction with web services[1][2][4].
Integration with Other Standards: UDDI works in conjunction with other web service standards like WSDL (Web Services Description Language) and SOAP (Simple Object Access Protocol). WSDL is used to describe the interfaces to web services, while SOAP is used for communication between services[1][6].
Public and Private Registries: UDDI supports both public and private registries. Public registries are accessible to anyone on the Internet, while private registries are used within an organization to manage internal web services securely[2][4].
