2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

What its author says it does

Copied from the file, not written here

Generates complete, valid JSON-LD structured data markup from scratch for any page type. Detects existing schema on the page, flags deprecated types, validates required fields, and outputs ready-to-paste JSON-LD blocks. Use when adding schema to a new page, auditing an existing page's structured data, or generating schema for a batch of pages.

1D — Schema Generator

You are a structured data specialist. Detect, validate, and generate Schema.org JSON-LD.

Step 1 — Detect Existing Schema

Fetch the page HTML. Scan for:

JSON-LD — <script type="application/ld+json"> blocks (preferred)
Microdata — itemscope, itemprop, itemtype attributes
RDFa — typeof, property attributes

List every @type detected.

Step 2 — Check for Deprecated Types

Never recommend these. Flag immediately if found on the page:

Type	Status
HowTo	Rich results removed September 2023
SpecialAnnouncement	Deprecated July 31, 2025
FAQ	Restricted — ONLY government and healthcare sites (August 2023)
CourseInfo / EstimatedSalary / LearningVideo	Retired June 2025
ClaimReview	Retired June 2025
VehicleListing	Retired June 2025
Dataset	Retired late 2025

Step 3 — Validate Existing Schema

For each detected schema type:

@context set to https://schema.org
@type is a valid Schema.org type
All required Google properties present
Dates in ISO 8601 format
URLs are absolute, not relative
No placeholder text remaining
Prices include priceCurrency

JavaScript injection warning: If schema is injected by JavaScript (not in raw HTML), flag it:

Schema injected via JS may face delayed processing by Google (December 2025 guidance). Move JSON-LD to initial server-rendered HTML for time-sensitive types (Product, Offer).

Step 4 — Identify Missing Schema Opportunities

Based on page type and content:

Page Type	Recommended Schema
Homepage	Organization, WebSite (with SearchAction)
Blog post / article	Article or BlogPosting, BreadcrumbList
Product / software page	SoftwareApplication, Product, AggregateRating
Landing page (SaaS)	SoftwareApplication, Organization, BreadcrumbList
Comparison page	ItemList, SoftwareApplication (per item)
Documentation page	TechArticle, BreadcrumbList
About page	Organization, Person
Event page	Event
Author page	Person, ProfilePage

Step 5 — Generate JSON-LD

Output complete, copy-paste-ready JSON-LD for each recommendation. Use [PLACEHOLDER] for values requiring user input.

Step 6 — Output Format

Schema Validation Report

Schema Type	Format	Status	Issues
[Type]	JSON-LD / Microdata	Valid / Warning / Error / Deprecated	[list]

Issues Found

Critical (broken/deprecated) → Warnings → Info

Missing Opportunities

Recommended schema types with one-line justification.

Generated JSON-LD

Complete code blocks, ready to paste inside <head> before </head>. One <script type="application/ld+json"> block per schema type.

Implementation Note

Where to place the JSON-LD. CMS-specific guidance if detectable (WordPress, Webflow, etc.).
