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.

  Class Description
Public class AccessControlledMetadataObject Obsolete. Represents 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 class Action Obsolete. Represents an action in the Business Data Catalog.
Public class ActionParameter Obsolete. Defines the parameters the action URL accepts.
Public class ApplicationRegistry Obsolete. Provides 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 class Association Obsolete. Represents a relationship between two or more related entities within a line-of-business (LOB) system.
Public class DataClass Obsolete. Represents the base class for all entities.
Public class DefaultValue Obsolete. Represents a default value for a part of an input parameter of a back-end method.
Public class DuplicateMetadataObjectException Obsolete. This 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 class Entity Obsolete. Represents an entity such as Customer or Product, in a line-of-business (LOB) application.
Public class ExceededMetadataObjectLimitException Obsolete. This exception is thrown when the metadata object limit is exceeded.
Public class Field Obsolete. Represents a column returned from the business application. This essentially wraps the TypeDescriptor describing the column in the metadata definition.
Public class FieldCollection Obsolete. Represents a collection of fields returned by a business application.
Public class FilterDescriptor Obsolete. Filters 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 class FilterDescriptorCollection Obsolete. Represents a collection of filters associated with an entity.
Public class Identifier Obsolete. Represents the persistent and unique identity of entity instances.
Public class IdentifierCollection Obsolete. Represents a collection of identifiers associated with an entity.
Public class InvalidMetadataObjectException Obsolete. This exception is thrown if the metadata object you are trying to access or create is invalid.
Public class InvalidMetadataPropertyException Obsolete. This exception is thrown if a metadata property is invalid.
Public class LobSystem Obsolete. Represents 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 class LobSystemInstance Obsolete. Represents an LobSystemInstance object that is registered in the Business Data Catalog.
Public class MetadataException Obsolete. Represents an exception thrown by a metadata object.
Public class MetadataObject Obsolete. Represents the abstract base class of the 13 metadata objects in the Business Data Catalog.
Public class MetadataObjectNotFoundException Obsolete. This exception is thrown if the requested metadata object cannot be found in the Business Data Catalog.
Public class Method Obsolete. Represents 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 class MethodInstance Obsolete. Describes how to call a method. A MethodInstance object is a reference to a method, plus the default values for the parameters.
Public class MissingMetadataPropertyException Obsolete. This exception is thrown if a metadata object definition is missing a required property.
Public class NamedActionDictionary Obsolete. Represents a dictionary of Action objects from the Business Data Catalog.
Public class NamedActionParameterDictionary Obsolete. Represents a dictionary of ActionParameter objects from the Business Data Catalog.
Public class NamedAssociationDictionary Obsolete. Represents a dictionary of Association objects from the Business Data Catalog.
Public class NamedDataClassDictionary Obsolete. Represents a dictionary of DataClass objects from the Business Data Catalog.
Public class NamedEntityDictionary Obsolete. Represents a dictionary of Entity objects from the Business Data Catalog.
Public class NamedLobSystemDictionary Obsolete. Represents a dictionary of LobSystem objects from the Business Data Catalog.
Public class NamedLobSystemInstanceDictionary Obsolete. Represents a dictionary of LobSystemInstance objects from the Business Data Catalog.
Public class NamedMethodDictionary Obsolete. Represents a dictionary of Method objectsfrom the Business Data Catalog.
Public class NamedMethodInstanceDictionary Obsolete. Represents a dictionary of MethodInstance objects from the Business Data Catalog.
Public class NamedPropertyDictionary Obsolete. Represents a dictionary of Property objects from the Business Data Catalog.
Public class Parameter Obsolete. Represents the in, inout, out and return parameters of each method.
Public class ParameterCollection Obsolete. Represents a collection of Parameter objects.
Public class TypeDescriptor Obsolete. Defines the data type of a parameter for a method.
Public class TypeDescriptorCollection Obsolete. Represents a TypeDescriptor collection.
Public class View Obsolete. A View denotes the schema, or the set of fields contained by an Entity Instance.

  Enumeration Description
Public enumeration DirectionType Specifies the direction in which the parameter is passed between the Business Data Catalog and the business application.
Public enumeration MethodInstanceType Represents the type of a MethodInstance object.
