It provides a parser to convert PENMAN strings into graph objects, inspection and manipulation methods for the underlying triples and edges, and a serializer to write graphs back to PENMAN format with customizable formatting. The library also includes an AMR model with role inventory and graph transformations (reification, canonicalization, etc.), plus a command-line tool for non-Python workflows.\n\nYou use it when you need to work with semantic graph data in PENMAN format: reading annotated AMR corpora, programmatically building or modifying semantic graphs, validating graphs against a model, or converting between different graph representations. It handles metadata in comments and surface alignments, and lets you restructure graphs before serialization\u2014adjusting indentation, selecting different root nodes, or relabeling variables.","worth_installing":"Yes. Penman is a stable, well-maintained library with no dependencies, permissive licensing, and active repository support. It fills a clear need for anyone working with PENMAN-formatted semantic graphs, especially in NLP and AMR research. The recent commit history confirms ongoing maintenance."},"id":"penman","links":{"html":"https://skillfed.io/packages/penman","md":"https://skillfed.io/packages/penman.md","pypi":"https://pypi.org/project/penman/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2024-08-07","license_spdx":null,"license_treatment":"permissive","name":"Penman","python_support":"supports_current","summary":"PENMAN notation for graphs (e.g., AMR)"},"popularity":{"monthly_downloads":84523,"position":13990,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.3.1"}
