## What it is
A Ruby on Rails ActiveRecord plugin that adds list management capabilities to models via an integer position column. It provides methods for sorting, reordering, and repositioning records within scoped lists.

## Use cases
- reorder todo items in a list with drag and drop positions
- maintain ordered records in rails with a position column
- move records to top or bottom of a scoped list
- implement sortable lists in a rails app
- manage sequential ordering of database rows in ruby

## When to choose
- you use Rails/ActiveRecord and need simple sequential ordering of records
- you need scoped lists where ordering is maintained per parent record
- you want a mature, well-tested gem for list positioning

## When to avoid
- you need multiple lists per table with unique position constraints - consider the Positioning gem instead
- you are not using ActiveRecord or Ruby
- you need relative/fractional positioning for frequent reordering

## Facets
- artifact type: plugin
- maturity: active
- function: orm, database
- domain: web-development, backend, databases
- platform: ruby, jvm
- tags: activerecord, rails, gem, ordering, positioning, sortable-lists
