HATEOAS Resource Model for Networked Storage Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Networked storage environments face challenges in providing a simple and efficient mechanism for clients to access information regarding resources, as existing systems often require complex searches to obtain related resource details, such as cluster and storage volume information.
Innovation Solution
The implementation of a resource model that generates HATEOAS links between resources, allowing clients to access related resource information through a unique resource identifier, and populates these links dynamically in response to requests, using a processor to identify relationship types and store relationship information in a searchable shell structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional resource information access mechanism is used, then clients can access resource information, but complex searches are required to obtain related resource details
Solution Approach 1:
The system pre-generates HATEOAS links that encode relationships between resources in advance. When a resource is requested, the system already has the relationship information prepared and can immediately populate it, eliminating the need for complex searches at access time.
Solution Approach 2:
HATEOAS links serve as an intermediary mechanism between resource identifiers and relationship information. Instead of directly querying complex relationship databases, clients use these standardized links as a mediator to access related resource details through a simplified interface.
2Loss of information
If additional searches are performed to obtain related resource details, then complete resource information can be obtained, but operational efficiency decreases
Solution Approach 1:
The system merges the resource identification and relationship information retrieval into a single operation. By embedding relationship links within the resource model itself, clients can obtain both the resource details and related information in one request, eliminating multiple separate searches.
Solution Approach 2:
Relationship information is prepared and structured in advance within the shell structure, allowing the system to immediately populate HATEOAS links when resources are requested, rather than performing searches at the moment of access.
3Ease of operation
If a simple access mechanism is implemented, then ease of use improves, but the ability to provide related resource information may be limited
Solution Approach 1:
The HATEOAS link mechanism serves multiple functions simultaneously: it provides a simple access interface for clients while also encoding rich relationship information between resources. This universal mechanism handles both basic resource identification and complex relationship navigation through a unified approach.
Solution Approach 2:
The standardized HATEOAS links act as an intermediary that preserves information completeness while maintaining simplicity. These links encode relationship metadata that enables clients to discover related resources without exposing the complexity of the underlying data structure.

AI summary
Methods and systems for a networked storage system are provided. One method includes registering a resource model by a processor having a plurality of objects, each object representing a plurality of resources of a networked storage system in a same format for storing attributes of any resource type. The resource model includes a plurality of relationship objects identifying relationship types for related resources of the plurality of resources. The method includes using the resource model by the processor, to generate an empty output array for the plurality of resources by iteratively processing the relationship objects of the resource model; and dynamically populating the empty output array by the processor, in response to an application programming interface (API) request for information regarding a resource, by updating the placeholder link providing a link to the resource identified by the request.
