Schema.org Type Generator

• schema.org
• google structured data

This generator is for those who like type safety and do not want to lookup the possible keys for Google structured data and other implementations of schema.org.

How it works :

The code generator scrapes schema.org collecting a type map, field definitions, data types, comments and notes. All this is converted to one of the supported languages. The result is a package which you import in your own project and use to write ld+json's.

Generate

$ schema-org-gen --help
usage: schema-org-gen [<flags>] <command> [<args> ...]

A generator for schema.org types

Flags:
  --help   Show context-sensitive help (also try --help-long and --help-man).
  --clean  Fetch the typemap from schema.org before generating.

Commands:
  help [<command>...]
    Show help.

  go
    Generate for Go

  php
    Generate for php

Using the generated types

Go

The generate package is a bit large and it might be better in some cases to copy/paste the types you need.

go get github.com/romainmenke/schema-org-gen/schemaorggo

package main

import (
	"fmt"
	"time"

	"github.com/romainmenke/schema-org-gen/schemaorggo"
)

func main() {
	// Create an object of the correct Type
	airline := schemaorggo.Airline{}

	// Set some properties
	airline.Name = []string{"Super Sonic"}

	foundingDate, err := time.Parse("2006-01-02", "2001-01-01")
	if err != nil {
		panic(err)
	}
	dissolutionDate, err := time.Parse("2006-01-02", "2002-02-02")
	if err != nil {
		panic(err)
	}

	// Some types need to be cast to "schemaorggo" variants
	airline.FoundingDate = []schemaorggo.Date{
		schemaorggo.Date(foundingDate),
	}
	airline.DissolutionDate = []schemaorggo.Date{
		schemaorggo.Date(dissolutionDate),
	}

	// Define a nested object
	founder := &schemaorggo.Person{}
	founder.Name = []string{"John"}
	airline.Founder = []*schemaorggo.Person{
		founder,
	}

	b, err := json.Marshal(airline)
	if err != nil {
		panic(err)
	}

	fmt.Println(string(b))
	// Output: {"@context":"http://schema.org","@type":"Airline","dissolutionDate":"2002-02-02","founder":{"@context":"http://schema.org","@type":"Person","name":"John"},"foundingDate":"2001-01-01","name":"Super Sonic"}
