jadn 0.5.7

JADN schema tools

JADN is used to process Information Models as described in RFC 8477, and to validate and serialize Information objects. The software is organized by function:

• core: Load, validate, and save a JADN schema.

• codec: Validate, encode, and decode application information using a specified data format:

  • Idiomatic (verbose) JSON

  • Minimized (concise) JSON

  • CBOR*

  • XML*

• convert: Convert JADN schema between JSON and documentation formats:

  • text-based Interface Definition Language (IDL)

  • html tables

  • markdown tables

• transform: Process a JADN schema to produce another JADN schema:

  • combine definitions from separate schemas into a single schema

  • split a schema that defines multiple objects into separate schemas for each object

  • remove unused definitions

  • delete or truncate comments

• translate: Convert a JADN schema into a concrete schema language:

  • JSON Schema

  • XSD*

  • CDDL*

  • Protobuf*

* Planned

Quickstart

The quickstart.py script from https://github.com/davaya/jadn-pypkg/tree/master/distribution illustrates how to use these functions:

• define and validate a schema

• convert the schema into documentation formats

• truncate comments

• translate JADN to JSON Schema

• validate and serialize test messages to:

  • JSON data format

  • Minimized-JSON data format
