Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing protocols, such as OData, lack the ability to automatically generate parameter and filter contextual URIs, leading to error-prone and inconsistent URI generation when accessing data services, which complicates the process of accessing specific resources with applied parameters and filters.

Innovation Solution

A data service class object is used to represent a set of resources with applied parameters and filters, enabling the automatic generation of parameter and filter contextual URIs through an algorithm that extracts and transforms name-value pairs and filter range items into valid OData URIs, ensuring consistency and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual URI generation is used, then flexibility in accessing resources is maintained, but error-proneness and inconsistency increase

Engineering Contradiction:

ImproveURI generation accuracyVSAvoidURI generation complexity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The data service class object automatically generates its own contextual URIs by combining its identifier with stored parameter and filter information, eliminating the need for external manual construction and ensuring consistency between the object state and the generated URI

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces an intermediary mechanism that bridges the data service class object and the URI generation process, using the object's stored parameters and filters as intermediaries to automatically construct accurate contextual URIs without manual intervention

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If parameters and filters are stored separately, then data structure simplicity is maintained, but URI generation consistency deteriorates

Engineering Contradiction:

ImproveParameter-filter consistencyVSAvoidData service class structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges the storage of parameters and filters directly within the data service class object, combining what could be separate entities into a unified structure that ensures consistency between the object's state and its generated URIs

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The data service class object serves multiple functions: it represents the data service, stores identification information, maintains parameter and filter information, and automatically generates contextual URIs, making it a multi-functional entity that eliminates the need for separate structures

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Disclosed herein are system, method, and computer program product embodiments for accessing a data service using a data service Uniform Resource Identifier (URI) object. An embodiment operates extracting a name-value pair of each parameter stored in the data service class object. The embodiment generates a parameter context URI using the one or more extracted name-value pairs according to a data service specification of the data service. The embodiment extracts one or more filter range items for each filter option stored in the data service class object. The embodiment generates a filter context URI using the one or more extracted filter range items according to the data service specification of the data service. The embodiment generates a context URI using the parameter context URI and the filter context URI. The embodiment then accesses the data service according to the context URI.
