TagsPlus

Description

Plugin for Omeka Classic. Replaces the default Tags Browse page with an enhanced interface offering improved usability and additional tag management tools.

Features

Browse & Edit

Full-width layout, optimised for all screen sizes
Inline tag search with autocomplete
Filter by record type
Sort by name, count or date created
Collapsible editing instructions with visual reference

Inline Rename

Click any tag name to edit it directly in the list. Press Enter to save or ESC to cancel.

Merge

When renaming a tag, if the new name matches an existing tag the system warns the user and offers the option to merge the two tags. The source tag's records are reassigned to the target tag, and the source tag is deleted. (requires admin/super/contributor role)

Search Similar Tags

Detects pairs of tags with similar names using the Levenshtein distance algorithm. Results are displayed in a paginated table, with buttons to merge each pair in either direction. (requires admin/super/contributor role)

Tools

Available to admin and super users from the dedicated tab:

Delete Unused Tags — deletes all tags not associated with any record
Convert Case — converts all tag names to UPPERCASE, lowercase, or First Letters Uppercase; tags that become identical after conversion are automatically merged
Subject to Tag — synchronizes Tags with DC.Subject metadata entries, creating new tags from subjects not yet present as tags

Installation
