It follows object-oriented and ontological principles, making it useful for domains like healthcare and bioinformatics where semantic interoperability matters. The package includes command-line tools and a Python API for schema generation, validation, and conversion.\n\nYou author schemas in YAML, then use LinkML's generators to produce the formats your downstream systems need. It depends on a substantial set of libraries\u2014including jsonschema, rdflib, pydantic, and sqlalchemy\u2014to handle schema validation, RDF processing, and data serialization. The project is actively maintained and supports modern Python versions.","worth_installing":"Yes, if you need to author schemas once and generate multiple formats (JSON Schema, RDF, ShEx) from a single source. The active maintenance, permissive license, low install friction, and support for current Python versions make it a solid choice. No known vulnerabilities. Best suited for teams working with linked data, semantic web standards, or multi-format schema requirements."},"id":"linkml","links":{"html":"https://skillfed.io/packages/linkml","md":"https://skillfed.io/packages/linkml.md","pypi":"https://pypi.org/project/linkml/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-20","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"linkml","python_support":"supports_current","summary":"Linked Open Data Modeling Language"},"popularity":{"monthly_downloads":446587,"position":6611,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.11.1"}
