## What it is
A Ruby library from the Rails project that provides app-wide URIs (gid://app/Model/id) for uniquely identifying model instances across different classes. It supports signed and expiring identifiers for tamper-proof, time-limited references, with built-in Active Record integration.

## Use cases
- pass model references to background jobs without serializing objects
- build dropdowns mixing Users and Groups with a universal identifier
- create expiring share links for documents
- sign identifiers to prevent tampering
- locate records from a URI string

## When to choose
- you're on Rails or Active Record and need uniform references to heterogeneous models
- you need signed or expiring identifiers for secure resource links
- you're building job scheduling that references records by ID

## When to avoid
- you're not using Ruby or a framework with a find-by-id model pattern
- you need cross-service identifiers rather than app-wide ones
- you just need primary keys within a single model class

## Facets
- artifact type: library
- maturity: stable
- function: serialization, security
- domain: developer-tools, web-development, apis
- platform: ruby
- tags: active-record, uri, signed-identifiers, background-jobs, rails-ecosystem
