It represents each activity as a planning problem with three components: a categorized object list, an initial state with ground literals, and a goal condition expressed as a logical formula. The language is simulator-agnostic\u2014it specifies only the state that must be reached for success, not how an agent achieves it.\n\nTo use BDDL, you either work with it standalone (parsing activity definitions and evaluating conditions via stub backends) or integrate it with a simulator like OmniGibson by implementing a BDDLBackend subclass and object-state predicates. The package includes logic evaluation and a basic solver for ground goal solutions. It depends on pytest, numpy, networkx, jupytext, future, and nltk, making installation heavyweight.","worth_installing":"No\u2014the repository is archived and abandoned; no active maintenance since the latest commit. The unclear license, high install friction (6 dependencies), and lack of Python version specification create friction. Install only if you are actively contributing to or maintaining a fork, or integrating with an existing BEHAVIOR simulator project that requires this exact version."},"id":"bddl","links":{"html":"https://skillfed.io/packages/bddl","md":"https://skillfed.io/packages/bddl.md","pypi":"https://pypi.org/project/bddl/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2025-06-23","license_spdx":null,"license_treatment":"unclear","name":"bddl","python_support":"unspecified","summary":null},"popularity":{"monthly_downloads":100016,"position":13005,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"3.6.0"}
