  • Merge duplicate entries (e.g., "Sci-Fi" and "Science Fiction")
  • Rename or split metadata values in bulk
  • Clean up inconsistencies from different sources
  • View and filter all metadata with comprehensive statistics
Pro Tip

Use the Metadata Manager regularly after adding new books to maintain a clean, organized library.

✨ Key Features & Capabilities​

📊 Comprehensive Metadata Views​

  • 7 Metadata Categories: Manage Authors, Genres, Moods, Tags, Series, Publishers, and Languages
  • Smart Statistics: See book counts for each metadata value
  • Powerful Filtering: Search and filter across thousands of entries
  • Sortable Tables: Sort by name or book count

🔄 Bulk Operations​

  • Merge Multiple Items: Combine duplicate or similar entries
  • Rename Entries: Update metadata values across all books
  • Split Values: Convert single entries into multiple tags
  • Delete Unwanted Data: Remove metadata from books in bulk

📖 Understanding Metadata Types​

Multi-Value Fields​

These fields allow books to have multiple values:

  • Authors 👤: Books can have multiple authors
  • Genres 🏷️: Books can belong to multiple genres
  • Moods ❤️: Books can have multiple mood tags
  • Tags 🔖: Books can have unlimited custom tags

Example Operations:

  • Merge "Sci-Fi" and "Science Fiction" into "Science Fiction, Sci-Fi" (both tags)
  • Split "Mystery & Detective" into "Mystery, Detective" (two separate tags)

Single-Value Fields​

These fields allow only one value per book:

  • Series 📚: Each book belongs to one series (or none)
  • Publisher 🏢: Each book has one publisher
  • Language 🌐: Each book is in one language

Example Operations:

  • Merge "En", "English", "en-US" into "English" (standardized)
  • Rename "Penguin Books Inc." to "Penguin Books"
Important - Single-Value Fields

For single-value fields (Series, Publisher, Language), merge operations standardize all selected values to one target value.

⚠️ Important Notes​

Data Safety​

No Undo Available

Merge, rename, and delete operations cannot be undone. Always read confirmation dialogs carefully and consider backing up your database before major changes.

Test First

Try operations on a few items before bulk actions to build confidence with the tools.

Performance Considerations​

  • Large Libraries: Operations on thousands of books may take a few seconds
  • Filtered Tables: Selection works on filtered results
  • Real-time Updates: Changes apply immediately across the application

Limitations​

Remember
  • Metadata is case-sensitive ("fiction" ≠ "Fiction")
  • Leading/trailing spaces matter ("Author" ≠ "Author ")
  • Single vs Multi-Value fields have different merge behaviors

🆘 Troubleshooting​

"Merge Selected" Button is Disabled​

Cause: You need at least 2 items selected

Solution: Select more items by checking their boxes

Changes Don't Appear Immediately​

Cause: Browser cache or table not refreshed

Solution:

  • Wait a moment for the table to reload
  • Refresh the page if needed
  • Check the All Books view to verify changes

Can't Find a Specific Entry​

Cause: Searching with wrong case or spelling

Solution:

  • Try different search terms
  • Sort the table alphabetically
  • Check for special characters or extra spaces
Search Tip

Metadata is case-sensitive. Try searching with different capitalization if you can't find an entry.

Accidentally Deleted Metadata​

Cause: No undo feature available

Solution:

  • Re-add metadata manually to affected books
  • Restore from backup if available
  • Use book edit feature to add back metadata
Prevention

Always verify the list of affected books before confirming deletion operations.

Merge Created Too Many Tags​

Cause: Used commas when single value intended

Solution:
