Conception and Development of a Metadata Search Portal Based on the Data Dictionary Minimal Information Model (DDMIM)...

Area of Science:

• Health Informatics
• Data Science
• Medical Research

Background:

• Metadata heterogeneity poses a significant challenge in the healthcare sector.
• The Data Dictionary Minimal Information Model (DDMIM) is developed to enhance interoperability between diverse data standards and dictionaries.
• Facilitating seamless metadata exchange is crucial for effective health data management.

Purpose of the Study:

• To present the design and development of a metadata search portal.
• The portal is based on the DDMIM specification to enhance health data discoverability and accessibility.
• A key objective is to improve interoperability across different health datasets.

Main Methods:

• A literature review was performed to identify relevant existing metadata repositories.
• Metadata from various sources were mapped and transformed into the DDMIM format.
• Requirements for a prototype search portal integrating diverse public metadata repositories were evaluated.

Main Results:

• A DDMIM-based search portal effectively integrates heterogeneous metadata sources.
• The portal significantly improves the ability to find relevant health datasets.
• Demonstrated capability to consolidate disparate metadata into a unified, searchable format.

Conclusions:

• The developed portal supports the integration of heterogeneous metadata, aligning with FAIR principles.
• Optimizes the utilization of health data for both research and clinical applications.
• Addresses critical challenges in medical data integration and utilization, promoting data-driven healthcare advancements.
