Semantic Validation Rules

Feature Request 🛍️

Document the semantic validation rules for the Concerto AST.

Use Case

Allows alternate implementation of semantic validation to be developed, perhaps outside of core.

Rules (from v4)

• CLASS_DECLARATION_001: No property name should be a system property: ModelUtil.isSystemProperty(thing.name)
• CLASS_DECLARATION_002: Property $class should be a property type from the metamodel
• CLASS_DECLARATION_003: Name of declaration should not be duplicated within the same model file
• CLASS_DECLARATION_004: If declaration has a super type it must exist
• CLASS_DECLARATION_005: If declaration has an identifying field it must have a corresponding String or String scalar property
• CLASS_DECLARATION_006: Identifying fields cannot be optional
• CLASS_DECLARATION_007: If system identified then the super type must also be system identified
• CLASS_DECLARATION_008: Check that property does not already exist in super types
• DECLARATION_001: Check name are unique within model file
• DECLARATION_002: Check declared name is not also an imported type
• DECORATED_001: Check decorator is not applied more than once
• MAP_DECLARATION_001: Must contain key and value properties // doesn't sound like semantic validation!
• MAP_KEY_TYPE_001: Key type must be a String or DateTime, or a scalar thereof
• MAP_VALUE_TYPE_001: Value type must exist
• MODEL_ELEMENT_001: Must have a $class attribute that is in the metamodel namespace
• MODEL_ELEMENT_002: name must be a valid identifier ModelUtil.isValidIdentifier(this.ast.name)
• MODEL_FILE_001: All imports must reference types that exist
• MODEL_FILE_002: Cannot import two versions of the same namespace
• NUMBER_VALIDATOR_001: Cannot have no upper bound and no lower bound
• NUMBER_VALIDATOR_002: Lower bound must not be greater than upper bound
• PROPERTY_001: Property must have a name // not semantic validation?
• PROPERTY_002: The type of a non-primitive property must exist
• PROPERTY_003: Property meta type must exist in the metamodel // new!
• RELATIONSHIP_001: Relationships cannot be to primitive types
• RELATIONSHIP_002: Relationship type must exist
• RELATIONSHIP_003: Relationship must be to an identified type
• STRING_VALIDATOR_001: Cannot have no upper and no lower bound
• STRING_VALIDATOR_002: Upper and lower bound must be positive integers
• STRING_VALIDATOR_003: Lower bound cannot be greater than upper bound
• STRING_VALIDATOR_004: If regex defined it must be valid
