Alter Traits

Overview of the AlterTraits Operation

What is AlterTraits?

The AlterTraits operation is a projection operation in CDM that modifies the traits or trait groups of a specified set of attributes from the source. Traits in CDM are metadata elements that define characteristics, behaviors, or constraints of attributes, enhancing their semantic meaning and utility within data models.

Key Characteristics:

  • Trait Modification: Alters existing traits or trait groups for selected attributes, enabling customization of attribute metadata.

  • Selective Application: Applies changes only to specified attributes, leaving others unaffected unless explicitly targeted.

  • Wildcard Support: Supports the use of wildcards in trait arguments, allowing for dynamic and flexible trait modifications.

  • Non-Destructive: Does not remove or rename attributes; it only modifies their associated traits based on the operation's configuration.

Purpose in GRIx

Within GRIx, the AlterTraits operation serves to:

  • Enhance Metadata: Refine or extend the metadata associated with attributes to better align with analytical and reporting needs.

  • Facilitate Data Integration: Adjust traits to support integration with other data sources or systems by ensuring consistent metadata.

  • Improve Data Analysis: Enable more precise and meaningful data analysis by tailoring attribute traits to reflect specific requirements or contexts.

  • Maintain Data Integrity: Ensure that attributes possess the appropriate traits, promoting consistency and reliability across data models.

By incorporating AlterTraits, GRIx data models become more adaptable and informative, supporting comprehensive risk assessments and decision-making processes.

Functionality and Behavior

How AlterTraits Works

The AlterTraits operation modifies the traits of specified attributes during the resolution process. Here's a detailed breakdown of its functionality:

  1. Input Attributes: The operation accesses the current list of resolved attributes from the source entity or previous operations in the projection pipeline.

  2. Attribute Selection: Users specify a set of attributes whose traits are to be altered. This selection can be based on explicit attribute names or patterns using wildcards.

  3. Trait Modification:

    • Traits to Add (traitsToAdd): Specifies new traits or trait groups to be added to the selected attributes. Traits can include references to existing traits or trait groups.

    • Traits to Remove (traitsToRemove): Specifies traits to be removed from the selected attributes if they exist.

  4. Wildcard Replacement (argumentsContainWildcards):

    • If set to true, the operation replaces wildcard placeholders in trait arguments with dynamic values based on the attribute's context.

    • Supported wildcards include {a/A}, {m/M}, {mo/Mo}, and {o}, each replacing with specific context-related values:

      • {a}: Replaced with the attribute name of the projection owner.

      • {m}: Replaced with the resolved name of the current member attribute (maintaining case).

      • {mo}: Replaced with the original name of the current member attribute (maintaining case).

      • {A}, {M}, {Mo}: Similar to their lowercase counterparts but with the first letter capitalized.

      • {o}: Replaced with the index of the attribute after an array expansion or an empty string if not applicable.

  5. Conditional Application (applyTo):

    • An optional property that specifies a list of attributes whose traits should be modified.

    • If provided, only the attributes in this list will undergo trait modifications; others will remain unchanged.

  6. Final Attribute List: The operation outputs the final list of attributes, including both modified and unmodified attributes based on the operation's configuration.

Default Behavior

  • Non-Destructive: Attributes not specified in the applyTo list are added to the final attribute set without any trait modifications.

  • Trait Preservation: Unless explicitly removed, existing traits remain intact, ensuring that only desired trait changes are applied.

  • Sequential Processing: When multiple projection operations are chained, AlterTraits processes traits based on the sequence of operations, allowing for layered trait modifications.

API Reference

For detailed technical specifications and additional configuration options, refer to the AlterTraits API Documentation.

Configuration Options

The AlterTraits operation can be customized using several properties to control its behavior during the projection process.

Mandatory Properties

  • $type: Specifies the operation type. For AlterTraits, this should be set to "alterTraits".

  • traitsToAdd: An array defining the traits or trait groups to be added to the selected attributes. Each entry can include:

    • traitReference: The reference to the trait or trait group to be added.

    • arguments: (Optional) An array of arguments to be passed to the trait, supporting wildcard replacements if argumentsContainWildcards is true.

Optional Properties

  • traitsToRemove: An array of trait names to be removed from the selected attributes if they exist.

  • applyTo: An array specifying the names of attributes whose traits are to be modified. If omitted, all attributes from the source are considered.

  • argumentsContainWildcards: A boolean flag indicating whether the trait arguments contain wildcards that need to be replaced with dynamic values.

  • explanation: Provides a description of what the operation does. Useful for documentation and maintenance purposes.

  • condition: A logical expression that determines whether the operation should execute based on predefined tokens and operators.

Detailed Examples

To provide a clearer understanding of how the AlterTraits operation functions within GRIx, the following examples illustrate its application in various contexts relevant to GRIx’s areas of focus and targets.

Example 1: Using AlterTraits on a Type Attribute

Scenario: Modifying traits in a type attribute within an entity to adjust its update requirements based on age milestones. For instance, altering the job attribute in the PersonInfo entity to include update requirements at ages 18, 30, and 45 while removing the requirement at age 60.

GRIx Area of Focus: Data Governance and Compliance

Target: Adjust trait specifications to align with updated compliance requirements for data attributes based on age-related milestones.

                            "means.requiredUpdateAtAge60"
                        ]
                    }
                ]
            }
        }
    ]
}

Explanation:

  • Entity: PersonInfo extends CdmEntity and includes attributes legalName and job.

  • Attribute job: The alterTraits operation modifies the job attribute by:

    • Adding Traits: means.requiredUpdateAtAge18 and the trait group AllRequiredUpdate.

    • Removing Trait: means.requiredUpdateAtAge60.

  • Result: The job attribute now requires updates at ages 18, 30, and 45, but not at age 60.

Resulting Resolved PersonInfo Entity:

Attribute

Newly Added Traits or Updated Arguments

legalName

job

means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

Concrete Relation to GRIx: By modifying traits on the job attribute, GRIx ensures that data governance policies are up-to-date with current compliance requirements. This operation enhances the PersonInfo entity by enforcing necessary update cycles based on age milestones, thereby maintaining data accuracy and relevance.

Example 2: Using AlterTraits on an Entity Attribute

Scenario: Editing traits across multiple attributes within an entity to enforce update requirements at specific age milestones. For example, modifying all relevant attributes in the PersonInfo entity to include update requirements at ages 18, 30, and 45 while removing the requirement at age 60.

GRIx Area of Focus: Risk Assessment and Prioritization

Target: Standardize trait modifications across multiple attributes to ensure consistent update requirements.

            ],
            "source": "Person"
        }
    }
}

Explanation:

  1. Initial alterTraits Operation:

    • Purpose: Adds means.requiredUpdateAtAge18 and the trait group AllRequiredUpdate to all attributes retrieved from the source.

    • Removal: Removes the trait means.requiredUpdateAtAge60 from all applicable attributes.

  2. Nested alterTraits Operation:

    • Purpose: Specifically adds the means.requiredUpdateDate trait with arguments month: 5 and day: 15 to the name attribute.

    • Application: Targets only the name attribute as specified in the applyTo list.

Resulting Resolved PersonInfo Entity Typed Attributes:

Attribute

Newly Added Traits or Updated Arguments

name

means.requiredUpdateDate(5, 15)

means.requiredUpdateAtAge18

means.requiredUpdateAtAge30

means.requiredUpdateAtAge45

address

means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

phoneNumber

means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

email

means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

Concrete Relation to GRIx: By applying AlterTraits to the entire entity, GRIx ensures that all relevant attributes within PersonInfo adhere to standardized update requirements. This operation enforces consistency across the data model, facilitating streamlined risk assessments and maintaining data integrity.

Example 3: Using AlterTraits When Extending an Entity

Scenario: Modifying traits in attributes inherited from a base entity when creating a derived entity. For instance, extending the Person entity to create a Child entity and altering traits in inherited attributes to enforce update requirements at specific age milestones.

GRIx Area of Focus: Demographic Analysis and Risk Assessment

Target: Ensure that derived entities maintain appropriate trait configurations for inherited attributes to support specialized risk assessments.

Base Entity Definition:

                            },
                            {
                                "name": "day",
                                "value": "15"
                            }
                        ]
                    }
                ],
                "applyTo": [
                    "email"
                ]
            }
        ],
        "runSequentially": true
    },
    "hasAttributes": []
}

Explanation:

  1. Entity: Child extends the Person entity, inheriting all its attributes.

  2. First alterTraits Operation:

    • Purpose: Adds means.requiredUpdateAtAge18 and the trait group AllRequiredUpdate to all inherited attributes.

    • Removal: Removes the trait means.requiredUpdateAtAge60 from all inherited attributes.

  3. Second alterTraits Operation:

    • Purpose: Specifically adds the means.requiredUpdateDate trait with arguments month: 5 and day: 15 to the email attribute.

    • Application: Targets only the email attribute as specified in the applyTo list.

  4. Sequential Execution: The runSequentially flag ensures that operations are executed in the order they are defined, maintaining the integrity of trait modifications.

Resulting Resolved Child Entity:

Attribute

Newly Added Traits or Updated Arguments

name

means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

address

means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

phoneNumber

means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

email

means.requiredUpdateDate(5, 15) means.requiredUpdateAtAge18 means.requiredUpdateAtAge30 means.requiredUpdateAtAge45

Concrete Relation to GRIx: When extending entities, it is crucial to ensure that inherited attributes comply with the derived entity's specific requirements. By using AlterTraits, GRIx allows for precise control over trait configurations in derived entities, ensuring that attributes like email adhere to updated compliance standards, thereby supporting targeted risk assessments and demographic analyses.

Example 4: Using AlterTraits on an Attribute Group

Scenario: Modifying traits within an attribute group to enforce comprehensive update requirements across a set of related attributes. For instance, applying trait modifications to all attributes within the PersonAttributeGroup in the PersonInfo entity.

GRIx Area of Focus: Operational Efficiency and Data Reusability

Target: Streamline trait modifications across grouped attributes to ensure consistency and reduce redundancy.

Example 5: Using AlterTraits with Wildcards

Scenario: Applying trait modifications to dynamically named attributes resulting from array expansions using wildcards. For instance, after expanding an array of Person entities into multiple attributes (name_1, address_1, etc.), using AlterTraits to add expansion-specific traits.

GRIx Area of Focus: Advanced Analytical Capabilities

Target: Enable dynamic trait assignments based on attribute naming patterns, facilitating detailed tracking and analysis of expanded data structures.

Projection Steps:

  1. ArrayExpansion: Expands the twoPeople array into multiple attributes with indexed names (name_1, address_1, etc.).

  2. RenameAttributes: Renames the expanded attributes to include ordinal indicators (name_1, address_1, etc.).

  3. AlterTraits: Applies the has.expansionInfo.list trait to each expanded attribute, utilizing wildcards for dynamic argument replacement.

Projection with AlterTraits and Wildcards:

                        "argumentsContainWildcards": true
                    }
                ],
                "runSequentially": true
            }
        }
    ]
}

Explanation:

  1. Entity: PersonInfo includes an id attribute and a polymorphic twoPeople attribute referencing the Person entity.

  2. ArrayExpansion Operation:

    • Purpose: Expands the twoPeople array into two separate sets of attributes (name_1, address_1, phoneNumber_1, email_1 and name_2, address_2, phoneNumber_2, email_2).

  3. RenameAttributes Operation:

    • Purpose: Renames the expanded attributes to include ordinal indicators, facilitating unique identification of each set.

  4. AlterTraits Operation:

    • Purpose: Applies the has.expansionInfo.list trait to each expanded attribute.

    • Wildcards Usage:

      • {a}: Replaced with the attribute name of the projection owner (twoPeople).

      • {o}: Replaced with the ordinal index (1, 2).

      • {mo}: Replaced with the original member attribute name (e.g., name, address).

    • ArgumentsContainWildcards: Set to true to enable dynamic replacement of wildcard placeholders.

  5. Result: Each expanded attribute receives a trait that includes dynamic information about its expansion context.

Resulting Resolved PersonInfo Entity:

Concrete Relation to GRIx: By utilizing wildcards in trait arguments, GRIx allows for dynamic and context-aware trait assignments during complex projection operations. This capability is essential for handling expanded data structures, ensuring that each expanded attribute carries metadata that accurately reflects its position and origin within the data model, thereby enhancing analytical depth and traceability.

Best Practices

To maximize the effectiveness of the AlterTraits operation within GRIx, adhere to the following best practices:

1. Consistent Naming Conventions

  • Clarity: Ensure that the names of traits clearly reflect their purpose and the nature of the attributes they modify.

  • Avoid Conflicts: Use unique and descriptive names to prevent conflicts with existing traits or other trait modifications.

Example:

Instead of naming a trait modification updateRequirement, use a more descriptive name like means.requiredUpdateAtAge18.

2. Strategic Application of applyTo

  • Selective Modification: Use the applyTo property to target specific attributes for trait modifications, ensuring that only relevant attributes are altered.

  • Avoid Overreach: Prevent unintended trait modifications by precisely specifying attribute targets.

Example:

When modifying traits for the job attribute, explicitly set applyTo to include only job to avoid altering other attributes unintentionally.

3. Effective Use of Wildcards

  • Dynamic Trait Arguments: Leverage wildcards in trait arguments to enable dynamic and context-sensitive trait assignments, especially when dealing with expanded or patterned attribute names.

  • Maintain Readability: Ensure that wildcard replacements result in meaningful and readable trait arguments to maintain the clarity of trait definitions.

Example:

Using {a}, {o}, and {mo} to dynamically insert attribute names, ordinals, and member attribute names when applying traits to expanded attributes.

4. Comprehensive Documentation

  • Provide Explanations: Utilize the explanation property to document the purpose and reasoning behind each trait modification.

  • Maintain Up-to-Date Documentation: Ensure that explanations are kept current with any changes to the data model or trait configurations.

Example:

{
    "$type": "alterTraits",
    "traitsToAdd": [
        {
            "traitReference": "means.requiredUpdateAtAge18"
        }
    ],
    "traitsToRemove": [
        "means.requiredUpdateAtAge60"
    ],
    "applyTo": [
        "job"
    ],
    "explanation": "Adding required update traits for the job attribute at ages 18, 30, and 45 while removing the requirement at age 60."
}

5. Reuse and Standardization of Traits

  • Promote Reusability: Define standard traits and trait groups that can be reused across multiple entities and attributes to maintain consistency.

  • Standardize Trait Definitions: Maintain a centralized repository of trait definitions to ensure uniform application across the data model.

Example:

Creating a CommonUpdateTraits trait group that includes all required update traits and reusing it across various entities and attributes.

6. Validate Trait Modifications

  • Consistency Checks: After applying trait modifications, validate the resolved entity to ensure that traits have been correctly added or removed.

  • Automated Testing: Incorporate automated tests to verify the integrity of trait modifications, especially after complex projection operations.

Example:

Using CDM’s validation methods to ensure that the PersonInfo entity has the correct traits applied to each attribute.

codevar resolvedEntity = await corpus.CreateResolvedEntityAsync("PersonInfo", "default", "alterTraits");
resolvedEntity.Validate();

7. Minimize Redundancy

  • Avoid Duplicate Traits: Ensure that traits are not redundantly added to attributes, which can lead to confusion and increased complexity.

  • Efficient Trait Management: Add traits only when necessary to maintain a streamlined and efficient data model.

Example:

Before adding a trait like means.requiredUpdateAtAge18, verify whether it already exists to prevent duplication.
