OData Error Target Messaging for Partial Processing Failures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
OData protocol does not provide a mechanism for an OData service to inform an HTTP-based application about partial request processing failures, where some parts of the request are successfully processed while others are not, without indicating the specific errors.
Innovation Solution
Introducing a new type of HTTP response message that includes an HTTP response header specifying the target field with an error and a human-readable error message, allowing the application to display additional information to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If OData service processes requests with partial failures, then request processing capability is improved, but error information delivery is worsened
Solution Approach 1:
The patent segments the error information delivery by introducing a separate `errorTargets` collection in the OData response. This allows the successful request processing to be maintained while error details are delivered through a dedicated structure that identifies specific target entities and their associated errors, resolving the contradiction between processing capability and error information delivery.
Solution Approach 2:
The patent implements feedback mechanisms by providing detailed error information back to the client application through the `errorTargets` collection. Each error target includes identifiers and error messages that feed back to the application, enabling it to present meaningful error information to users while maintaining the ability to process requests with partial failures.
2Ease of operation
If OData service provides detailed error information, then user experience is improved, but response message complexity is worsened
Solution Approach 1:
The patent segments error information into a dedicated `errorTargets` collection within the response message. This structured approach organizes detailed error information (including target entity identifiers and error messages) in a predictable format, improving user experience while keeping the response structure manageable and not excessively complex.
3Difficulty of detecting and measuring
If OData protocol is extended with error target messaging, then error identification capability is improved, but protocol complexity is worsened
Solution Approach 1:
The patent extends the OData protocol with a universal `errorTargets` collection structure that can be applied across different service scenarios. This multi-functional error messaging mechanism provides consistent error identification capability while adding minimal protocol complexity by building upon existing OData response structures.
Data Source
AI summary
Provided are systems and methods which provide an OData messaging protocol for HTTP messages that are processed successfully but with some errors. In one example, the method may include transmitting a HTTP request to an OData service, the HTTP request comprising identifiers of one or more input fields and one or more values for the one or more input fields, receiving, from the OData service, an HTTP response indicating that the HTTP request was processed successfully with one or more errors, identifying an input field which is a target of the error and a reason for the error from a field in the HTTP response indicating that the HTTP request was processed successfully with one or more errors, and rendering, via the application, a visual identifier of the error in association with a display of the input field on the user interface.
