AI-powered metadata correction and harmonization workflow developed on AWS
Key points
- Addresses metadata standardization bottleneck with AI.
- Workflow built on AWS, using Amazon Bedrock for LLM-powered alignment.
- Includes human-in-the-loop validation for user approval.
- Supports consistency and interoperability across data sources.
The Challenge of Metadata Standardization
The rapid increase in data collection and generation has created a gap between raw data production and the capacity to standardize it. Manual metadata harmonization, which involves standardizing labels, identifiers, and formats, often delays analysis and limits the value of shared datasets.
AI-Powered Solution for Metadata Management
An AI-powered approach to metadata correction and harmonization transforms this process, allowing it to scale with increasing data volumes. This method aims to convert metadata management from a time-consuming task into an efficient process that supports open science.
Workflow Built on AWS
A centralized metadata correction and harmonization workflow has been developed on AWS to ensure consistency, interoperability, and accuracy across various metadata sources. The system utilizes Amazon Bedrock for large language model (LLM)-powered schema alignment and correction recommendations. Other AWS services include Amazon S3 for storage, Amazon DynamoDB for job tracking, Amazon Cognito for authentication, and Amazon ECS for compute.
Operational Process
The system operates as a cyclical workflow. Users upload metadata files, which then undergo parallel validation streams: schema alignment for column structures and metadata field validation for individual values. When issues are detected, the system generates correction recommendations, and users retain final authority over changes.

A new workflow built on AWS uses AI for metadata correction and harmonization, addressing the challenge of standardizing large volumes of data. This system aims to automate the process of aligning metadata schemas and validating data integrity, which traditionally has been a manual bottleneck in data analysis.
