Microsoft.Office.Server.ApplicationRegistry.MetadataModel Namespace

Allows the reading of the metadata objects from, and execution of the business logic described in, the metadata database.

Because it is cached and fast, clients that need to query the metadata database for metadata information should use the MetadataModel namespace instead of the Microsoft.Office.Server.Administration namespace, which is read/write.

Public classAccessControlledMetadataObjectRepresents a Business Data Catalog metadata object whose access can be controlled by permissions. All 13 metadata objects and ApplicationRegistry inherit from this class and therefore, can be controlled by permissions. This class cannot be instantiated.
Public classActionRepresents an action in the Business Data Catalog.
Public classActionParameterDefines the parameters the action URL accepts.
Public classApplicationRegistryProvides access to all the line-of-business (LOB) systems and LOB system instances registered in the Business Data Catalog. This is the top-level object in the Business Data Catalog's object model. It enables you to read all the metadata objects including LOB system, entities, and methods.
Public classAssociationRepresents a relationship between two or more related entities within a line-of-business (LOB) system.
Public classDataClassRepresents the base class for all entities.
Public classDefaultValueRepresents a default value for a part of an input parameter of a back-end method.
Public classDuplicateMetadataObjectExceptionThis is just like the InvalidMetadataObjectException class, except that it includes a reference to the duplicate object as well as which field is causing the collision. These fields are not guaranteed to be populated; it is a best effort. When they are populated, they will contain the correct information.
Public classEntityRepresents an entity such as Customer or Product, in a line-of-business (LOB) application.
Public classExceededMetadataObjectLimitExceptionThis exception is thrown when the metadata object limit is exceeded.
Public classFieldRepresents a column returned from the business application. This essentially wraps the TypeDescriptor describing the column in the metadata definition.
Public classFieldCollectionRepresents a collection of fields returned by a business application.
Public classFilterDescriptorFilters are the fundamental way in which the Business Data Catalog captures user (or system) input and plumbs it through to the backend API invocation. FilterDescriptors describe where in a complex series of parameters, a filter value should be inserted. This is accomplished by 'tagging' the TypeDEscriptors representing complex parameters of a Method definition to flag where the insertion should happen. It is important to note that the backend must supply the functionality for filtering; the FilterDescriptors merely form a mechanism to surface this to the end user. FilterDescriptor objects are owned (contained) inside Method objects. They are subsequently referred by TypeDescriptor objects.
Public classFilterDescriptorCollectionRepresents a collection of filters associated with an entity.
Public classIdentifierRepresents the persistent and unique identity of entity instances.
Public classIdentifierCollectionRepresents a collection of identifiers associated with an entity.
Public classInvalidMetadataObjectExceptionThis exception is thrown if the metadata object you are trying to access or create is invalid.
Public classInvalidMetadataPropertyExceptionThis exception is thrown if a metadata property is invalid.
Public classLobSystemRepresents a source of business data, business logic, or both. SAP R/3 IDES, Siebel 7.5, and AdventureWorks SQL Server 2000 sample database are examples of LobSystem objects.
Public classLobSystemInstanceRepresents an LobSystemInstance object that is registered in the Business Data Catalog.
Public classMetadataExceptionRepresents an exception thrown by a metadata object.
Public classMetadataObjectRepresents the abstract base class of the 13 metadata objects in the Business Data Catalog.
Public classMetadataObjectNotFoundExceptionThis exception is thrown if the requested metadata object cannot be found in the Business Data Catalog.
Public classMethodRepresents operations related to an entity that you can perform in the line-of-business (LOB) application. Methods represent pointers to business logic in a business application. Examples of methods are "get a list of customers," "get the order with a specified ID," and "update the unit price of a product."
Public classMethodInstanceDescribes how to call a method. A MethodInstance object is a reference to a method, plus the default values for the parameters.
Public classMissingMetadataPropertyExceptionThis exception is thrown if a metadata object definition is missing a required property.
