Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to facilitate data interworking between data platforms using different standards, such as oneM2M and NGSI-LD systems, to enable seamless data sharing and integration in the IoT ecosystem.
Innovation Solution
A data interworking method involving an Interworking Proxy Entity (IPE) that retrieves repositories, acquires mapping rules, and stores them to enable data interworking between oneM2M and NGSI-LD systems by subscribing to resources and entities, and storing notifications based on these rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data platforms use different standards (oneM2M and NGSI-LD), then each platform can optimize for its specific use case, but data interworking between platforms becomes difficult and complex
Solution Approach 1:
The patent introduces an Interworking Proxy Entity (IPE) that acts as an intermediary between oneM2M and NGSI-LD systems. The IPE retrieves repositories from both systems, extracts labels, acquires mapping rules from these labels, and stores them locally. This mediator handles the complexity of standard translation internally while presenting simple interfaces to both systems, thereby enabling data interworking without requiring direct complex integration between the two different standards.
2Reliability
If manual configuration of mapping rules is performed between systems, then data interworking can be achieved, but the process becomes time-consuming and difficult to maintain
Solution Approach 1:
The system performs preliminary actions by automatically retrieving repositories and extracting labels during system initialization or when new resources are added. The mapping rules are acquired and stored in advance through automated label extraction from repository metadata, rather than requiring manual configuration when interworking is needed. This preliminary automated setup significantly reduces configuration time and effort while maintaining reliable data interworking.

AI summary
There is provided a data interworking method between a oneM2M system and an NGSI-LD system. The data interworking method according to an embodiment of the present disclosure includes: retrieving, by an IPE, resources in the oneM2M system that perform data interworking with the NGSI-LD system; retrieving labels of the retrieved resources; acquiring a mapping-rule from the retrieved labels; and storing the acquired mapping-rule. Accordingly, data interworking between data platforms using different standards is performed more easily, so that technology may go one step further to the goal of interconnecting and servicing all things in a global environment as IoT ultimately pursues.
