Metadata Hex
Introduction
Metadata Hex is a powerful Drupal module that automates metadata extraction, processing, and mapping for nodes and files. It supports structured metadata ingestion from PDFs and Markdown, dynamically associating extracted values with Drupal fields. This module streamlines content management by automating metadata handling, ensuring data consistency, and reducing manual input.
Features
✅ Automated Metadata Extraction
- Extracts metadata from PDFs using Smalot\PdfParser.
- Extracts metadata from Markdown using Symfony\Yaml.
- Future support for additional file types via plugin-based handlers.
✅ Node & File Processing
- Automatically processes nodes upon insertion via hook_node_insert().
- Dynamically ingests and categorizes uploaded files.
✅ Configurable Mappings
- Maps extracted metadata to Drupal entity fields.
- Provides strict handling and data protection options.
✅ Batch Processing
- Supports bulk metadata extraction and node updates.
- Allows processing of entire directories and file attachments.
✅ Admin Configuration
- Fully manageable from the Drupal admin panel at /admin/config/metadata_hex.
