Update Action-definition.schema.json For JSON Logic Prerequisites

by ADMIN 66 views

Introduction

In the pursuit of refining our project's architecture, we have embarked on an initiative to integrate JSON Logic into action prerequisites. This involves updating the action-definition.schema.json file to align with the project's adoption of JSON Logic for condition evaluation. In this article, we will delve into the process of modifying the action-definition.schema.json file to replace the custom definitions/ConditionObject with a reference to the standard common/json-logic.schema.json for the prerequisites array items.

Background

The current action-definition.schema.json file utilizes a custom object structure (definitions/ConditionObject) within the properties/prerequisites array. This custom structure has served its purpose, but with the project's adoption of JSON Logic, it is essential to update the schema file to reflect this change. The goal is to remove the old definition and point the prerequisites items to the standardized JSON Logic schema.

Tasks

To accomplish this task, we will follow a series of steps:

Locate Files

The first step is to locate the action-definition.schema.json file and ensure that the target schema common/json-logic.schema.json is accessible at the correct relative path. This involves verifying the path based on the project structure, for example, ./common/json-logic.schema.json#.

Remove ConditionObject Definition

Next, we will delete the entire ConditionObject structure from the definitions section of action-definition.schema.json. This will involve removing the custom definition and any associated properties.

Update Prerequisites Items Reference

We will then modify the properties/prerequisites/items section to change the $ref value from #/definitions/ConditionObject to point directly to the JSON Logic schema. For example, we will update the $ref value to {"$ref": "./common/json-logic.schema.json#"}. It is essential to ensure that the properties/prerequisites field itself remains type: "array".

Update Prerequisites Description

We will also modify the description field within properties/prerequisites to clearly state that prerequisites are now defined as an array of standard JSON Logic rule objects and will be evaluated by the ConditionEvaluatorService (or JsonLogicEvaluationService). An example of the updated description field is:

"Optional. List of conditions that must all evaluate to true for the action to be valid. Each condition is a standard JSON Logic object (see common/json-logic.schema.json) evaluated by the ConditionEvaluatorService using the appropriate actor/target context. Evaluated AFTER basic component requirements."

Review and Save

Finally, we will carefully review the changes to ensure syntactical correctness and save the action-definition.schema.json file.

Acceptance Criteria

To ensure that the update is successful, we will verify the following acceptance criteria:

  • The definitions/ConditionObject structure is completely removed from action-definition.schema.json.
  • The properties/prerequisites field is of type: "array".
  • The properties/prerequisites/items field correctly uses $ref to point to the common/json-logic.schema.json schema file (or its confirmed path).
  • The properties/prerequisites/description field accurately reflects the use of JSON Logic objects for prerequisites.
  • The modified action-definition.schema.json file is syntactically JSON.

Dependencies

To complete this task, we rely on the following dependencies:

  • Ticket 1 (Schema Standard): common/json-logic.schema.json MUST be defined and available.

Estimate

The estimated time required to complete this task is small, as it involves only schema editing.

Conclusion

Introduction

In our previous article, we explored the process of updating the action-definition.schema.json file to align with the project's adoption of JSON Logic for condition evaluation. In this article, we will address some frequently asked questions (FAQs) related to this update.

Q: What is the purpose of updating the action-definition.schema.json file?

A: The purpose of updating the action-definition.schema.json file is to replace the custom definitions/ConditionObject with a reference to the standard common/json-logic.schema.json for the prerequisites array items. This update aligns with the project's adoption of JSON Logic for condition evaluation.

Q: Why is it necessary to remove the old definition and point the prerequisites items to the standardized JSON Logic schema?

A: The old definition (ConditionObject) is no longer necessary with the project's adoption of JSON Logic. By removing it and pointing the prerequisites items to the standardized JSON Logic schema, we ensure that the prerequisites array items are correctly referenced and evaluated.

Q: What is the significance of the # symbol in the $ref value?

A: The # symbol in the $ref value is used to indicate that the reference is to a specific version or revision of the schema. In this case, it is used to reference the common/json-logic.schema.json schema file.

Q: How do I verify the path of the common/json-logic.schema.json schema file?

A: To verify the path of the common/json-logic.schema.json schema file, you should check the project structure and ensure that the file is accessible at the correct relative path.

Q: What is the difference between the ConditionEvaluatorService and the JsonLogicEvaluationService?

A: The ConditionEvaluatorService and the JsonLogicEvaluationService are both used to evaluate conditions, but they serve different purposes. The ConditionEvaluatorService is used to evaluate conditions based on the old definition (ConditionObject), while the JsonLogicEvaluationService is used to evaluate conditions based on the standardized JSON Logic schema.

Q: How do I ensure that the modified action-definition.schema.json file is syntactically valid JSON?

A: To ensure that the modified action-definition.schema.json file is syntactically valid JSON, you should carefully review the changes and use a JSON validation tool to check for any errors.

Q: What are the dependencies required to complete this task?

A: The dependencies required to complete this task are:

  • Ticket 1 (Schema Standard): common/json-logic.schema.json MUST be defined and available.

Q: What is the estimated time required to complete this task?

A: The estimated time required to complete this task is small, as it involves only schema editing.

Conclusion

In conclusion, updating the action-definition.schema.json file to align with the project's adoption of JSON Logic for condition evaluation is a crucial step in refining our project's. By addressing the FAQs related to this update, we can ensure that the prerequisites array items are correctly referenced to the standardized JSON Logic schema, and the action-definition.schema.json file is syntactically valid JSON.
