Searching by Classification

Classification objects classify or categorize objects in the registry by using unique concepts (ClassificationNodes) that define valid values within a classification scheme. The classification scheme is the parent in a tree hierarchy that contains generations of child concepts. Table 1–3 describes the classification schemes provided by the Registry specifications. Many of the terms in this table are defined in the Registry specifications.

Table 1–3 Classification Scheme Usage


Classification Scheme Name	Usage	Description or Purpose
`AssociationType`	Frequently	Defines the types of associations between RegistryObjects. Used as the value of the `associationType` attribute of an `Association` instance to describe the nature of the association.
`ContentManagementService`	Rarely	Defines the types of content management services. Used in the configuration of a content management service, such as a validation or cataloging service.
`DataType`	Frequently	Defines the data types for attributes in classes defined by this document. Used as the value of the `slotType` attribute of a `Slot` instance to describe the data type of the `Slot` value.
`DeletionScopeType`	Occasionally	Defines the values for the `deletionScope` attribute of the `RemoveObjectsRequest` protocol message.
`EmailType`	Rarely	Defines the types of email addresses.
`ErrorHandlingModel`	Rarely	Defines the types of error handling models for content management services.
`ErrorSeverityType`	Rarely	Defines the different error severity types encountered by the Registry while processing protocol messages.
`EventType`	Occasionally	Defines the types of events that can occur in a registry.
`InvocationModel`	Rarely	Defines the different ways that a content management service can be invoked by the Registry.
`NodeType`	Occasionally	Defines the different ways in which a `ClassificationScheme` can assign the value of the `code` attribute for its `ClassificationNode` (Concept) objects.
`NotificationOptionType`	Rarely	Defines the different ways in which a client can be notified by the registry of an event within a `Subscription`.
`ObjectType`	Occasionally	Defines the different types of RegistryObjects a registry may support.
`PhoneType`	Rarely	Defines the types of telephone numbers.
`QueryLanguage`	Rarely	Defines the query languages supported by the Registry.
`ResponseStatusType`	Rarely	Defines the different types of status for a `RegistryResponse`.
`StatusType`	Occasionally	Defines the different types of status for a `RegistryResponse`.
`SubjectGroup`	Rarely	Defines the groups that a user can belong to for access control purposes.
`SubjectRole`	Rarely	Defines the roles that can be assigned to a user for access control purposes.

In the menu area, the root of the ClassificationSchemes tree is below the Description field.

To Search by Classification

Steps

Expand the root node to view the full list of classification schemes.

The number in parentheses after each entry indicates how many concepts (ClassificationNode objects) the parent contains.

Expand the node for the classification scheme you want to use.

Expand concept nodes beneath the classification scheme until you find the leaf node by which you want to search. A leaf node is a node with no concepts beneath it.

Select the leaf node.

(Optional) Restrict the search by choosing an object type or specifying a name or description string.
