[SEO] structured content with LD-JSON

Here is a bunch of code i want to share

I had to implement microdata in community and looking in google specifiction i saw LD-JSON format which sounds to be easier to manipulate than microformat

https://developers.google.com/search/docs/guides/intro-structured-data

So here is my code 

<#if config.getString("phase", "prod") == "stage"> 
		<#assign endpoint="http://community.stage.brandname.com/" />
	<#else>
		<#assign endpoint="http://communaute.brandname.com/" />	
		<@liaMarkupCache ttl="6000000" variation="node" anonymousOnly="false" />
</#if>

<script type="application/ld+json">
{
  "@context": "http://schema.org",
	"@type": "Organization",
	"name": "${text.format('brandName')}",
	"logo": {
		"@type": "ImageObject",
		"url": "${asset.get("/html/assets/logo_inline.png")}",
		"width": 600,
		"height": 60
			},
	"url": "${endpoint}",
	"sameAs": [
		"https://www.facebook.com/brandName",
		"https://www.youtube.com/user/brandName"
	]
}
</script>


<#if page.name="CommunityPage">	
	<script type="application/ld+json">
		{
		  "@context": "http://schema.org",
		  "@type": "WebSite",
		  "name": "${coreNode.title}",
		  "url": "${endpoint}",
		  "potentialAction": {
			"@type": "SearchAction",
			"target": "${endpoint}/t5/forums/searchpage/tab/message?q={search_term_string}",
			"query-input": "required name=search_term_string"
		  }
		}
	</script>
	

<#else>

	<script type="application/ld+json">
	{
	  "@context": "http://schema.org",
	  "@type": "BreadcrumbList",
	  "itemListElement": [
		<#list page.content.nav.breadcrumb.crumbs as crumb>
		{
		"@type": "ListItem",
		"position": ${crumb?counter},
		"item": {
		  "@id": "${crumb.url}",
		  "name": "${crumb.text}"
		}
		
	  }<#if crumb?has_next>,</#if></#list>]
	}
	</script>
	
	
	
</#if>
<#if page.name="BlogArticlePage">

	<#--                    -->
	<#-- getData : call to the macros-->
	<#--                    -->
	<#include "queryhandler"/>
	<#assign messageDataQuery = rest("2.0","/search?q=" + "SELECT * FROM messages WHERE id = '${page.context.thread.topicMessage.uniqueId}'"?url) />
 <#--     call to a macro which render imageURL and image Caption according to dimensions               -->	
<@getMessageImage imageDimensions="" messageId=page.context.thread.topicMessage.uniqueId />

		<script type="application/ld+json">	
		{
		  "@context": "http://schema.org",
		  "@type": "Article",
		  "mainEntityOfPage": {
			"@type": "WebPage",
			"@id": "${page.context.thread.topicMessage.webUi.url}"
		  },
		  "headline": "${page.context.thread.topicMessage.subject}",
		  <#if messageImageURL?? && messageImageURL!="">
		  "image": {
			"@type": "ImageObject",
			"url": "${endpoint}${messageImageURL}",
			"height": ${messageImageHeight},
			"width": ${messageImageWidth}
		  },
		  </#if>
		  "datePublished": "${page.context.thread.topicMessage.postDate?datetime}",
		  "dateModified": "${messageDataQuery.data.items[0].current_revision.last_edit_time?number_to_datetime}",
		  "author": {
			"@type": "Person",
			"name": "${page.context.thread.topicMessage.author.login}"
		  },
		   "publisher": {
			"@type": "Organization",
			"name": "${text.format('brandName')}",
			"logo": {
			  "@type": "ImageObject",
			  "url": "${asset.get("/html/assets/logo_inline.png")}",
			  "width": 600,
			  "height": 60
			}
		  },
		  "description": "${messageDataQuery.data.items[0].teaser}"
		}
		</script>
	
</#if>

this is working good but for blogArticles, google seems to require AMP-page. Looking for the AMP specifications, it looks hard to respect them in lithium.

Did someone tried to do so?
