It sits between zope.event (which provides generic event notification) and application code, offering a standard vocabulary for lifecycle events so that loosely-coupled components can react to object state changes without direct dependencies on one another.\n\nThe package is part of the Zope ecosystem and is typically used in component-based architectures where multiple subsystems need to be aware of object changes without tight coupling. It depends on zope.interface and zope.event, and is designed to have minimal external dependencies so that packages can rely on it without pulling in heavy frameworks. The library is stable (Production/Stable status), supports modern Python versions (3.9\u20133.13), and has been maintained since 2007.","worth_installing":"Yes, if you are building a Zope-based or component-oriented system that uses zope.event for event dispatch. The package is stable, has no known vulnerabilities, and provides a standard event vocabulary that reduces coupling. No, if you are not already using zope.event or zope.interface\u2014the package is tightly scoped to that ecosystem and offers little value outside it. Maintenance is aging but not abandoned; releases are infrequent but track current Python versions."},"id":"zope-lifecycleevent","links":{"html":"https://skillfed.io/packages/zope-lifecycleevent","md":"https://skillfed.io/packages/zope-lifecycleevent.md","pypi":"https://pypi.org/project/zope-lifecycleevent/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-09-12","license_spdx":null,"license_treatment":"unclear","name":"zope.lifecycleevent","python_support":"supports_current","summary":"Object life-cycle events"},"popularity":{"monthly_downloads":165725,"position":10518,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"6.0"}
