XSD To JSON Schema

Transforming XSD files into JSON Schema

Python script that converts XSD files into JSON Schema.

For example, transforming:

<?xml version="1.0" encoding="UTF-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
	<xs:element name="example" type="xs:string" nillable="true" />
</xs:schema>

Into:

{
    "properties": {
        "example": {
            "type": "string"
        }
    },
    "required": [
        "example"
    ],
    "$schema": "http://json-schema.org/schema#"
}

USAGE

CLI

Output JSON schema to stdout.

xsdtojson [PATH TO XSD FILE] --pretty

Output JSON schema to file

xsdtojson [PATH TO XSD FILE] > [PATH TO JSON OUTPUT FILE]

PYTHON

from xsdtojson import xsd_to_json_schema
json_schema = xsd_to_json_schema([PATH TO XSD FILE])

TODO

• Convert XSD data types to JSON Schema types. See generateRS for possible mappings.
• Add JSON-LD URI to schema - potential refs:

  • https://gist.github.com/stain/7690362
  • http://json-schema.org/latest/json-schema-core.html#rfc.section.5.4
• Write tests. Ideally these will:
  • Build a JSON schema from XSD
  • Create & validate JSON-LD record
  • Use online JSON-LD=>RDF converter, and validated JSON_LD against original XSD.
• Convert more XSD sources:
