🎉 Project Summary - Dataverse Bulk Metadata Update Tool

Your enhanced Dataverse bulk metadata update repository has been successfully created! This is an advanced version of the original single-dataset tool, now supporting multiple datasets with specific DOIs.

📦 What Has Been Created

Core Features Implemented

✅ Multi-Dataset Support

  • Handle multiple datasets with different DOIs simultaneously
  • Bulk update files across all datasets in one workflow
  • CSV-based organization with DOI as first column

✅ Bidirectional Conversion

  • JSON → CSV: Convert JSON templates to editable CSV format
  • CSV → JSON: Convert updated CSV back to JSON files for Dataverse
  • Seamless bidirectional workflow for maximum flexibility

✅ Metadata Management

  • First column: DOI (dataset identifier)
  • Second column: Dataset name
  • File-level metadata: descriptions, file paths, labels
  • Track update status for each file

✅ Dataverse Integration

  • Direct API connection to Dataverse instances
  • Dry-run mode to preview changes before applying
  • Secure credential management via environment variables
  • Batch update capabilities

✅ ZIP and Folder Support

  • JSON files organized in data/json_templates/ folder
  • Support for multiple JSON files in a single directory
  • Easy to add/remove datasets

🚀 Quick Start (5 Minutes)

1. Setup Environment

python3 -m venv venv
source venv/bin/activate
pip install requests

2. Convert JSON to CSV

python json_to_csv.py \
    --input-dir ./data/json_templates \
    --output-csv ./data/metadata.csv

3. Edit Metadata

  • Open data/metadata.csv in Excel or Google Sheets
  • Update new_description and new_file_path columns
  • Save the file

4. Convert Back to JSON

python csv_to_json.py --csv-file ./data/metadata.csv

5. Push to Dataverse (Optional)

export DATAVERSE_SERVER_URL="https://your-dataverse.org"
export DATAVERSE_API_TOKEN="your-token"

python dataverse_api.py --csv-file ./data/metadata.csv --no-dry-run

📊 CSV Structure

The generated CSV has these columns:

Column Purpose Example
DOI Dataset identifier (read-only) doi:10.5061/dryad.example1
dataset_name Dataset name (read-only) Climate Data 2024
file_id File ID (read-only) file_001
file_label File name (read-only) temperature_data.csv
file_description Current description (read-only) Monthly average temperature...
file_path Current directory (read-only) raw_data
file_size File size in bytes (read-only) 2048576
file_type Data type (read-only) Text
original_description Backup of original (read-only) Same as file_description
new_description ✏️ EDIT THIS Updated description
new_file_path ✏️ EDIT THIS New directory path
status Update status pending, updated, no_changes

🎯 Supported Workflows

Workflow 1: Bulk Description Updates

JSON Files → CSV (auto-generated) → Edit descriptions → JSON → Dataverse

Workflow 2: File Path Reorganization

JSON Files → CSV → Update paths → JSON → Dataverse

Workflow 3: Multiple Dataset Management

Multiple JSON Files → Single CSV → Edit all datasets → Multiple JSONs → Dataverse

Workflow 4: Scheduled Updates

Cron Job → JSON → CSV → Updates → JSON → Dataverse (automated)

📋 Sample Data Included

Three sample datasets are included for testing:

  1. Climate Data 2024 - North America

    • 3 files: temperature data, precipitation analysis, methodology
    • DOI: doi:10.5061/dryad.example1

  2. Genomic Sequencing Dataset - Species A

    • 4 files: sequence reads (R1, R2), assembly summary, quality report
    • DOI: doi:10.5061/dryad.example2

  3. Survey Results - Consumer Preferences 2024

    • 4 files: survey responses, demographics, R script, findings report
    • DOI: doi:10.5061/dryad.example3

Total: 11 sample file records for testing
