Linked Open Data Modeling Language (LinkML)

LinkML is a powerful framework for defining data models, particularly for linked open data and semantic web applications. It allows users to define schemas using a YAML-based language, and then generate artifacts such as dataclasses, JSON schemas, ShEx schemas, and more, for various programming languages and data formats. It supports schema validation, data transformation, and integration with existing ontologies. The current version is 1.10.0, and it has an active development and release cadence, with major versions often introducing significant changes.
