BreadcrumbList

Реализуем с помощью стандартного pdoCrumbs

{$_modx->runSnippet('pdoCrumbs',[
	'showHome'=> 1,
	'showCurrent' => 1,
	'from' => '0'
	'tplWrapper'=> '@INLINE 
  <script type="application/ld+json">
  {
    "@context": "http://schema.org",
    "@type": "BreadcrumbList",
    "itemListElement": [ {$output} ]
  }
  </script>',
	'tplHome'=>'@INLINE 
  {
    "@type": "ListItem",
    "position": {$idx},
    "item":
      {
        "@id": "{$link}",
        "name": "Главная"
      }
  },',
	'tplCurrent'=>'@INLINE 
  {
    "@type": "ListItem",
    "position": {$idx},
    "item":
    {
    "@id": "{$link}",
    "name": "{$menutitle}"
    }
  }',
	'tpl'=>'@INLINE 
  {
    "@type": "ListItem",
    "position": {$idx},
    "item":
      {
        "@id": "{$link}",
        "name": "{$menutitle}"
      }
  },',
  ])}

Organization

Здесь просто подставляем переменные, обычно я пользуюсь компонентом ClientConfig.

{set $organization = [
    '@context' => 'https://schema.org',
    '@type' => 'Organization',
    'name' => 'company_name' | config,
    'url' => 'site_url' | config,
    'logo' => 'site_url' | config ~ 'assets/img/logo.png',
    'address' => [
        '@type' => 'PostalAddress',
        'streetAddress' => 'address' | config,
        'addressLocality' => 'city' | config,
        'postalCode' => 'index' | config,
        'addressCountry' => 'RU',
    ],
    'contactPoint' => [
      '@type' => 'ContactPoint',
      'telephone'=> 'phone' | config,
      'contactType' => 'customer service',
      'areaServed' => 'RU',
      'availableLanguage' => 'Russian'
   ]
]}
<script type="application/ld+json">
{json_encode($organization)}
</script>

BlogPosting

Выводим только на странице статьи. Можно поставить проверку в чанке, на то, какой шаблон.

{set $blog_posting = [
    '@context' => 'https://schema.org',
    '@type' => 'BlogPosting',
    'mainEntityOfPage' =>[
        '@type' => 'WebPage',
        '@id' => $_modx->makeUrl($_modx->resource.id, '','','https')
    ],
    'headline' => $_modx->resource.pagetitle,
    'description' => $_modx->resource.description,
    'image' => 'site_url' | config  ~ $_modx->resource.img,
    'author' =>[
        '@type' => 'Organization',
        'name' => 'company_name' | config
    ],
    'publisher' =>[
        '@type' => 'Organization',
        'name' => 'company_name' | config,
        'logo' =>[
            '@type' => 'ImageObject',
            'url' => 'site_url' | config ~ 'assets/img/logo.png'
        ],
    ],
    'datePublished' => $_modx->resource.publishedon | date_format : '%Y-%m-%d',
    'dateModified' => $_modx->resource.publishedon | date_format : '%Y-%m-%d',
]}
<script type="application/ld+json">
{json_encode($blog_posting)}
</script>

Order

{set $order = [
 '@context' => 'https://schema.org/',
 '@type' => 'Order',
 'seller' => [
   '@type' => 'Organization',
   'name' => 'company_name' | config,
   'telephone' => 'phone' | config,
  ]
]}

<script type="application/ld+json">
{json_encode($order)}
</script>

Product

{set $product = [
  '@context' => 'https://schema.org',
  '@type' => 'Product',
  'description' => 'introtext' | resource,
  'name' => $page,
  'image' => 'tv.image_preview' | resource,
  'offers' => [
      '@type' => 'Offer',
      'availability' => 'https://schema.org/InStock',
      'price' => 'tv.price' | resource,
      'priceCurrency' => 'RU'
  ]
]}

{'!msGallery' | snippet : [
    'tpl' => 'tpl.msGallery_new2',
    'limit' => '1'
    'toPlaceholder' => 'msimg'
]}

{if $_modx->resource.template == 3}
    {set $product = [
      '@context' => 'https://schema.org',
      '@type' => 'Product',
      'description' => 'introtext' | resource,
      'name' => $pagetitle,
      'image' => $_modx->getPlaceholder('msimg'),
      'offers' => [
          '@type' => 'Offer',
          'availability' => 'https://schema.org/InStock',
          'price' => $_modx->resource.price,
          'priceCurrency' => 'RU'
      ]
    ]}

<script type="application/ld+json">
{json_encode($product)}
</script>


Если белый экран, пробуйте так:

{set $organization = json_encode($organization) | replace : '{' : '{ '}
<script type="application/ld+json">
   {$organization}
</script>
