neverblink-linkml

Fast and robust LinkML schema validation and code generation for Python, backed by LinkML-Scala compiled to a native shared library.

Install

pip install neverblink-linkml

Usage

import linkml_scala

with linkml_scala.load_file("model.yaml") as schema:
    print(schema.json_schema())
    print(schema.shacl())
    for issue in schema.issues(linkml_scala.WARNING):
        print(issue["severity"], issue["message"])

load_file() will automatically resolve imports and parse the schema. You can reuse the Schema object for multiple generator calls, and it will automatically cache the parsed form of any imported schemas.

Generators available on a Schema: json_schema(), shacl(), rdfs(), linkml(), frictionless(), graphql(), er_diagram(), translation(), ossie(), and scala(), plus lint() for validation.

Going the other way, linkml_scala.from_ossie() reads an Apache Ossie (incubating) ontology and returns the corresponding LinkML schema as YAML or JSON.

To work from memory instead of the file system, use load_string() for a single schema or load_path() when imports are involved:

schema = linkml_scala.load_path("model.yaml", {
    "model.yaml": "...",
    "person.yaml": "...",  # referenced via `imports: - person`
})

Supported platforms

We provide both sdist (source distribution) and pre-built wheels for popular platforms (Linux, macOS, Windows, x86-64 and ARM64).

To build the package from source (sdist) you must have Java 17+ and Clang installed on your system. Please open an issue if you encounter any issues with the installation process.
