Very cool, I tried implementing metadata for Steemit posts on my [beyondboinc blog](view-source:https://beyondboinc.net/authors/cm-steem/gridcoin-community-hangout-034).

Format I used:
```
<script type="application/ld+json">
[
    {
        "@context": "http://schema.org", 
        "@type": "Article",
        "headline": "Gridcoin Community Hangout #034",
        "alternativeHeadline": "Gridcoin Community Hangout #034",
        "image": {
         "@type": "ImageObject",
         "@url": "https://beyondboinc.net/images/steem-logo.png",
         "@caption": "Steem-logo",
         "@height": "696",
         "@width": "696"
        },
        "author" : { "@type" : "Person", "name" : "cm-steem" },
        "editor": { "@type" : "Person", "name" : "cm-steem" },
        "citation": "https://steemit.com/@cm-steem/gridcoin-community-hangout-034/",
        "sameAs": "https://steemit.com/@cm-steem/gridcoin-community-hangout-034/",
        "genre": "gridcoin beyondbitcoin boinc cryptocurrency podcast ", 
        "keywords": "gridcoin beyondbitcoin boinc cryptocurrency podcast ",
        "articleSection": "gridcoin beyondbitcoin boinc cryptocurrency podcast ",
        "publisher" : { "@type" : "Organization", "name" : "Steemit" },
        "url": "https://beyondboinc.net/authors/cm-steem/gridcoin-community-hangout-034/",
        "mainEntityOfPage": {
         "@type": "WebPage",
         "@id": "https://beyondboinc.net/authors/cm-steem/gridcoin-community-hangout-034/"
        },
        "description": "Gridcoin Community Hangout #034",
        "articleBody": "Article content",
        "datePublished": "2017-06-30 02:16:45",
        "dateCreated": "2017-06-30 02:16:45",
        "dateModified": "2017-06-30 02:16:45"
    },
    {
        "@context": "http://www.schema.org",
        "@type": "WebSite",
        "name": "BeyondBOINC",
        "accountablePerson": "cm-steem",
        "accessModeSufficient": "textual, visual",
        "alternateName": "BeyondBoinc",
        "url": "https://beyondboinc.net"
    }
]
</script>
```

Great to see this effort to improve the metadata compatibility across steem applications, keep up the great work!
