metadata_hex 1.0.0

Metadata Hex (Heap EXport) is a Drupal module that facilitates metadata extraction, processing, and association with Drupal entities, particularly nodes and files. It supports structured metadata ingestion from PDFs and other file formats, mapping extracted values to Drupal fields dynamically.

Feature List

✅ 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 newly inserted nodes via `hook_node_insert()`.
• Supports dynamic file ingestion and categorization.

✅ Configurable Mappings

• Maps extracted metadata fields to Drupal entity fields.
• Includes strict handling and data protection options.

✅ Batch Processing

• Enables bulk metadata extraction and node updates.
• Allows processing of entire directories of files and attaching them to nodes.

✅ Admin Configuration Panel

• Fully configurable settings via **Configuration → Metadata Hex** (`/admin/config/metadata_hex`).
• Options for customizing metadata extraction, node processing, and file ingestion.

Installation & Configuration

1. Install the module via Drupal’s Extend menu or using `composer require drupal/metadata_hex`.
2. Navigate to **Configuration → Metadata Hex Settings** (`/admin/config/metadata_hex`).
3. Configure metadata extraction rules, field mappings, and processing options.
4. (Optional) Run batch processing manually for existing files.

Known Issues & Limitations

⚠️ Limited File Type Support
- Currently supports PDFs and Markdown; additional file handlers coming soon.

⚠️ Batch Processing Considerations
- Large metadata processing batches may require additional server resources.
