The package was forked in 2024 from the original python-ligo-lw project and provides core functionality to read, write, and interact with LIGOLW documents programmatically.\n\nThe library integrates with standard scientific Python dependencies (numpy, pyyaml, tqdm, python-dateutil) and the igwn-segments package to handle time-interval logic. It is classified as Mature and supports Python 3.9 through 3.14, with prebuilt wheels available for common platforms. The copyleft GPL-3.0-or-later license means any derivative work must remain open-source.","worth_installing":"Yes, if you work with LIGO gravitational-wave data or compact object detection pipelines. The package is mature, actively maintained (last release 207 days ago), has no known vulnerabilities, and provides the standard Python interface for LIGOLW I/O. The copyleft license is a constraint only if you need proprietary distribution. Medium install friction is acceptable for a specialized scientific library with prebuilt wheels."},"id":"igwn-ligolw","links":{"html":"https://skillfed.io/packages/igwn-ligolw","md":"https://skillfed.io/packages/igwn-ligolw.md","pypi":"https://pypi.org/project/igwn-ligolw/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2026-01-19","license_spdx":null,"license_treatment":"copyleft","name":"igwn-ligolw","python_support":"supports_current","summary":"Python LIGO Light-Weight XML I/O Library"},"popularity":{"monthly_downloads":97992,"position":13117,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.1.1"}
