Just what are the conventions of the ODataConventionModelBuilder?

Question

There are lots of examples of using ODataConventionModelBuilder with simple, contrived models, often just a single class.

But there's nothing that actually explains what the conventions are; how to code a model that complies with convention. There's no official documentation for it.

So what's the convention?

Answer 1

From what I've seen so far, the conventions are those used by Entity Framework, as opposed to any new ones for OData. Please correct me if I am wrong.

More on Code-first conventions, below, but there are many more in the Julie Lerman book I have yet I cannot find an exhaustive list of them on the web.

Update

The EF modelling conventions system is pluggable and each convention is represented by a class encapsulating the behaviour, and those classes are listed here:

However that doesn't help with which ones are applicable or used by the ODataConventionModelBuilder if any.

• AssociationInverseDiscoveryConvention - Provides convention to detect navigation properties to be inverses of each other when only one pair of navigation properties exists between the related types.
• AttributeToColumnAnnotationConvention - A general purpose class for Code First conventions that read attributes from .NET properties and generate column annotations based on those attributes.
• AttributeToTableAnnotationConvention - A general purpose class for Code First conventions that read attributes from .NET types and generate table annotations based on those attributes.
• ColumnAttributeConvention - Represents a convention to process instances of ColumnAttribute found on properties in the model.
• ColumnOrderingConvention - Represents a convention to apply column ordering specified via ColumnAttribute or theDbModelBuilder API.
• ColumnOrderingConventionStrict - Convention to apply column ordering specified via ColumnAttribute or theDbModelBuilder API. This convention throws if a duplicate configured column order is detected.
• ComplexTypeAttributeConvention - Represents the convention to process instances of ComplexTypeAttribute found on types in the model.
• ComplexTypeDiscoveryConvention - Represents a convention to configure a type as a complex type if it has no primary key, no mapped base type and no navigation properties.
• ConcurrencyCheckAttributeConvention - Represents the convention to process instances of ConcurrencyCheckAttributefound on properties in the model.
• Convention - A convention that doesn't override configuration.
• DatabaseGeneratedAttributeConvention - Represents a convention to process instances of DatabaseGeneratedAttribute found on properties in the model.
• DecimalPropertyConvention - Convention to set precision to 18 and scale to 2 for decimal properties.
• DeclaredPropertyOrderingConvention - Represents a convention to move primary key properties to appear first.
• ForeignKeyAssociationMultiplicityConvention - Represents a convention to distinguish between optional and required relationships based on CLR nullability of the foreign key property.
• ForeignKeyDiscoveryConvention - Represents a base class for conventions that discover foreign key properties.
• ForeignKeyIndexConvention - Represents a convention to introduce indexes for foreign keys.
• ForeignKeyNavigationPropertyAttributeConvention - Represents a convention to process instances of ForeignKeyAttribute found on navigation properties in the model.
• ForeignKeyPrimitivePropertyAttributeConvention - Represents a convention to process instances of ForeignKeyAttribute found on foreign key properties in the model.
• IdKeyDiscoveryConvention - Convention to detect primary key properties. Recognized naming patterns in order of precedence are: 1. 'Id' 2. [type name]Id Primary key detection is case insensitive.
• IndexAttributeConvention - A convention for discovering IndexAttributeattributes on properties and generatingIndexAnnotation column annotations in the model.
• InversePropertyAttributeConvention - Represents a convention to process instances of InversePropertyAttribute found on properties in the model.
• KeyAttributeConvention - Convention to process instances ofKeyAttribute found on properties in the model.
• KeyDiscoveryConvention - Represents a base class for conventions that discover primary key properties.
• ManyToManyCascadeDeleteConvention - Convention to add a cascade delete to the join table from both tables involved in a many to many relationship.
• MappingInheritedPropertiesSupportConvention - Convention to ensure an invalid/unsupported mapping is not created when mapping inherited properties
• MaxLengthAttributeConvention - Represents a convention to process instances of MaxLengthAttribute found on properties in the model.
• NavigationPropertyNameForeignKeyDiscoveryConvention - Convention to discover foreign key properties whose names are a combination of the dependent navigation property name and the principal type primary key property name(s).
• NotMappedPropertyAttributeConvention - Represents a convention to process instances of NotMappedAttribute found on properties in the model.
• NotMappedTypeAttributeConvention - Represents a convention to process instances of NotMappedAttribute found on types in the model.
• OneToManyCascadeDeleteConvention - Provides a convention to enable cascade delete for any required relationships.
• OneToOneConstraintIntroductionConvention - Provides a convention to configure the primary key(s) of the dependent entity type as foreign key(s) in a one:one relationship.
• PluralizingEntitySetNameConvention - Represents a convention to set the entity set name to be a pluralized version of the entity type name.
• PluralizingTableNameConvention - Represents a convention to set the table name to be a pluralized version of the entity type name.
• PrimaryKeyNameForeignKeyDiscoveryConvention - Convention to discover foreign key properties whose names match the principal type primary key property name(s).
• PrimitivePropertyAttributeConfigurationConvention - Base class for conventions that process CLR attributes found on primitive properties in the model.
• PropertyAttributeConfigurationConvention - Base class for conventions that process CLR attributes found on properties of types in the model.
• PropertyMaxLengthConvention - Represents a convention to set a maximum length for properties whose type supports length facets. The default value is 128.
• RequiredNavigationPropertyAttributeConvention - Convention to process instances ofRequiredAttribute found on navigation properties in the model.
• RequiredPrimitivePropertyAttributeConvention - Represents a convention to process instances of RequiredAttribute found on primitive properties in the model.
• SqlCePropertyMaxLengthConvention - Represents a convention to set a default maximum length of 4000 for properties whose type supports length facets when SqlCe is the provider.
• StoreGeneratedIdentityKeyConvention - Represents a convention to configure integer primary keys to be identity.
• StringLengthAttributeConvention - Represents a convention to process instances of StringLengthAttribute found on properties in the model.
• TableAttributeConvention - Represents a convention to process instances of TableAttribute found on types in the model.
• TimestampAttributeConvention - Represents a convention to process instances of TimestampAttribute found on properties in the model.
• TypeAttributeConfigurationConvention - Base class for conventions that process CLR attributes found in the model.
• TypeNameForeignKeyDiscoveryConvention - Convention to discover foreign key properties whose names are a combination of the principal type name and the principal type primary key property name(s).
