It integrates with the Zope component architecture (zope.interface, zope.component, zope.location, zope.proxy) to register and retrieve annotations through a clean adapter-based API. The package is particularly useful in ZODB-backed systems where you need to associate extra data with persistent objects.\n\nThe core mechanism uses IAnnotations adapters to store metadata, with AttributeAnnotations providing a dict-like interface for attribute-based storage. The package supports both in-memory dict storage and persistent BTrees storage, falling back gracefully if BTrees is unavailable. It has been actively maintained since 2007 and currently supports Python 3.9 through 3.13.","worth_installing":"Yes, if you are building within the Zope ecosystem or need a clean, non-invasive way to attach metadata to objects in a component-based architecture. The package is stable, actively maintained, and has no known vulnerabilities. The ZPL-2.1 license is OSI-approved but less mainstream; verify it aligns with your project before committing. Install friction is low and dependencies are all from the same ecosystem, so integration is straightforward for Zope-aware projects."},"id":"zope-annotation","links":{"html":"https://skillfed.io/packages/zope-annotation","md":"https://skillfed.io/packages/zope-annotation.md","pypi":"https://pypi.org/project/zope-annotation/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-09-12","license_spdx":null,"license_treatment":"unclear","name":"zope.annotation","python_support":"supports_current","summary":"Object annotation mechanism"},"popularity":{"monthly_downloads":150924,"position":10950,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"6.0"}
