UDDI Registry Entities

Use

Universal Description, Discovery and Integration (UDDI) is a platform-independent, XML-based registry for businesses to list themselves on the Internet.

The UDDI data model describes all entities in XML. It contains the following entities:

• businessEntity

  Describes a business or another organization that provides Web services.

• businessService

  Represents a logical grouping of Web services. A business service is always assigned to exactly one business entity.

• bindingTemplate

  Provides technical information to bind and interact with a Web service. A binding template is always assigned to exactly one business service.

• tModel

  tModels (technical models) represent a reusable concept and provide, for example, technical information about a Web service type, a protocol type used by a Web service, or a category system. A tModel is always assigned to exactly one binding template.

Additionally, UDDI provides the following entities for describing the above listed entities:

• categoryBag

  A category (bag) contains a list of descriptive elements, represented as tModels that describe an entity in more detail.

  A category can be defined for:

  • businessEntity

    It provides, for example, information about the geographical region or industry the business entity belongs to.

  • businessService

    It provides, for example, more detailed information about the geographical region or industry the business service belongs to.

  • bindingTemplate

    It provides, for example, information about the Web service, whether it is in the test or productive phase.

  • tModel

    keyedReferenceGroup

  Categories can be arranged in a category group with a keyedReferenceGroup.

• identifierBag

  An identifier (bag) contains additional identifiers for a business entity. An identifier can, for example, be a tax number or a D-U-N-S number.

• publisherAssertion

  Relates one business entity to another.
