A utility library for working with JSON Table Schema in Python.

A utility library for working with JSON Table Schema in Python.

• A core set of utilities for working with JSON Table Schema
• Use in other packages that deal with actual validation of data, or other 'higher level' use cases around JSON Table Schema (e.g.: Tabular Validator)
• Be 100% compliant with the the JSON Table Schema specification (we are not there yet)

• types: a collection of classes to validate type/format of data described by a JSON Table Schema
• models.JSONTableSchema: A model around a schema with useful methods for interaction
• infer: a utility that creates a JSON Table Schema based on a data sample
• validate: a utility to validate a schema as valid according to the current spec

Let's look at each of these in more detail.

from jsontableschema import types

Type and format checking for data values.

from jsontableschema.models import JSONTableSchema

A model of a schema with helpful methods for working with the data a schema represents.

from jsontableschema import infer

Give a sample of data, get back a schema for the data.

from jsontableschema import validate

Give a schema as any of JSON file, url to JSON file, or a Python dict, and get back a response as to whether it is valid.

JSON Table Schema features a CLI called jsontableschema. This CLI exposes the infer and validate functions for command line use.

> jsontableschema infer path/to/data.csv

The response is a schema as JSON.

> jsontableschema validate path/to-schema.json

The response is...
