It allows Python scripts to query and manage event dataset metadata\u2014including processing history, associated files, runs, and data tiers\u2014without directly calling HTTP endpoints. The library abstracts the REST layer and JSON serialization, providing a Pythonic interface to a CMS-internal data catalog.\n\nThe package depends on dbs3-pycurl for HTTP communication and requires libcurl to be installed on the system. Setup involves installing system libraries, configuring X.509 certificates for authentication, and exporting environment variables. It is designed for CMS physicists and data managers working with Monte Carlo simulations and recorded collision data.","worth_installing":"Yes, if you are a CMS physicist or data manager needing programmatic access to DBS3 from Python. No, if you are outside the CMS collaboration or need a general-purpose REST client\u2014the package is CMS-specific, dormant (last release 697 days ago), and requires non-trivial system setup (libcurl, X.509 certs). The low install friction and zero known vulnerabilities are offset by operational complexity and maintenance uncertainty."},"id":"dbs3-client","links":{"html":"https://skillfed.io/packages/dbs3-client","md":"https://skillfed.io/packages/dbs3-client.md","pypi":"https://pypi.org/project/dbs3-client/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2024-09-16","license_spdx":null,"license_treatment":"permissive","name":"dbs3-client","python_support":"unspecified","summary":null},"popularity":{"monthly_downloads":485720,"position":6396,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"4.0.19"}
