Linked data Modeling Language

LinkML is a general purpose modeling language that can be used with linked data, JSON, and other formalisms

Welcome to LinkML 👋

LinkML is a flexible modeling language that allows you to author schemas in YAML that describe the structure of your data. Additionally, it is a framework for working with and validating data in a variety of formats (JSON, RDF, TSV), with generators for compiling LinkML schemas to other frameworks.

Please submit all issues to the linkml/linkml repo. You can also vote for your favorite issue.

You can ask to join the linkml-community Google group (you need to have a Google account to join).
