## What it is
A Ruby on Rails plugin (gem) that adds flexible tagging to ActiveRecord models, supporting an arbitrary number of tag contexts such as skills, interests, or sports. It provides tag ownership, tag cloud calculations, finding related tagged objects, and tag parsing.

## Use cases
- add tags to Rails models with multiple contexts
- build a tag cloud for a Rails app
- find objects tagged with specific tags
- let users own their own tags on shared content
- find related objects by shared tags
- tag users with skills and interests separately

## When to choose
- you have a Rails/ActiveRecord app and need multi-context tagging
- you need tag ownership, tag clouds, or related-object queries out of the box
- you want a mature, widely used tagging solution for Ruby

## When to avoid
- you are not using Ruby on Rails or ActiveRecord
- you need full-text or faceted search rather than simple tagging
- you use a non-SQL database without ActiveRecord

## Facets
- artifact type: library
- maturity: stable
- function: orm, search-engine, plugin-system
- domain: web-development, backend, databases
- platform: ruby
- tags: rails, tagging, activerecord, gem, tag-clouds, tag-contexts, web-server
