Detect, validate, and generate Schema.org structured data. JSON-LD format preferred. Use when user says "schema", "structured data", "rich results", "JSON-LD", or "markup".

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.

What the file says

# Schema Markup Analysis & Generation

## Detection

1. Scan page source for JSON-LD `<script type="application/ld+json">`
2. Check for Microdata (`itemscope`, `itemprop`)
3. Check for RDFa (`typeof`, `property`)
4. Always recommend JSON-LD as primary format (Google's stated preference)

## Validation

- Check required properties per schema type
- Validate against Google's supported rich result types
- Test for common errors:
  - Missing @context
  - Invalid @type
  - Wrong data types
  - Placeholder text
  - Relative URLs (should be absolute)
  - Invalid date formats
- Flag deprecated types (see below)

## Schema Type Status (as of Feb 2026)

Read `references/schema-types.md` for the full list. Key rules:

### ACTIVE (recommend freely):

How to install

The exact contents, by fingerprint

mdr add hashgraph-online/awesome-codex-plugins/seo-schema@sha256:c90938a2d8b996b7

The line at the top of this page pins the label v1.7.0, 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.
