Create and manage JSON structures, import mappings and export mappings in MDL, plus the domain-model shapes they map onto. Use when turning a JSON payload into entities, mapping a REST or queue response, or exporting objects as JSON.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# JSON Structures, Import Mappings & Export Mappings

This skill covers creating and managing JSON structures, import mappings, and export mappings in Mendix using MDL.

## Key Concepts

### JSON Structures
A JSON structure defines the schema of a JSON payload. It stores a JSON snippet and auto-derives an element tree with paths, types, and custom names.

### Import Mappings

How to install

The exact contents, by fingerprint
mdr add mendixlabs/mxcli/json-structures-and-mappings@sha256:dec827ea35f96169

The line at the top of this page pins the label git:20261025.516f907, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
