## What it is
Doctrine Persistence is a PHP library providing common interfaces and abstractions shared by Doctrine's object mappers (ORM, ODM, etc.). It defines contracts for object managers, repositories, and persistence operations rather than implementing storage itself.

## Use cases
- decouple application code from a specific Doctrine object mapper implementation
- type-hint against stable persistence interfaces in PHP libraries
- build custom object mappers compatible with the Doctrine ecosystem
- swap between Doctrine ORM and MongoDB ODM without changing persistence code
- write framework integrations that support any Doctrine mapper

## When to choose
- you are building a PHP library that should work with any Doctrine object mapper
- you need stable interfaces for object persistence instead of concrete ORM dependencies
- you are developing a custom Doctrine-compatible mapper or integration

## When to avoid
- you need an actual working ORM with query building and database drivers - use Doctrine ORM instead
- your project does not use Doctrine or its ecosystem
- you want a standalone persistence solution with no Doctrine dependency

## Facets
- artifact type: library
- maturity: stable
- function: orm, database, serialization, sdk
- domain: databases, developer-tools, backend
- platform: php, cross-platform
- tags: persistence, object-mapper, interfaces, doctrine, abstraction-layer, php
