To whom does "author" refer when using schema.org's "MusicAlbum" schema?

Question

I am trying to encode reviews of music albums. If I understand the "MusicAlbum" schema correctly, the =reviewer= is the "author" of the "review" content? Can anyone point me to examples of well-constructed reviews (MusicAlbum" or otherwise)? Likewise, what is the best way to note the language in which the MusicAlbum is recorded--in my case, often not the same as the language of the review?

Answer 1

It is correct to think that the reviewer would be the Author according to the Review schema. The MusicAlbum schema specifies that the inLanguage value regards the language in which the music was recorded.

Here's an example I quickly threw together that might explain how you can implement a Review into a Music Album:

{
  "@context": "http://schema.org",
  "@type": "MusicAlbum",
  "byArtist": {
    "@type": "MusicGroup",
    "name": "Radiohead"
  },
  "genre": "Alt/Punk",
  "image": "king-of-limbs.jpg",
  "name": "King of Limbs",
  "numTracks": "8",
  "track": [
    {
      "@type": "MusicRecording",
      "duration": "PT5M14S",
      "name": "Bloom",
      "url": "/artist/radiohead/album/the-king-of-limbs/track/bloom"
    },
    {
      "@type": "MusicRecording",
      "duration": "PT4M40S",
      "name": "Morning Mr Magpie",
      "url": "/artist/radiohead/album/the-king-of-limbs/track/morning-mr-magpie"
    }
  ],
  "url": "/artist/radiohead/album/the-king-of-limbs",
    "inLanguage": "english",
    "review": [
        {
            "@type": "Review",
            "author": "Reviewer Bob",
            "datePublished": "2015-11-30",
            "description": "Writing a review for Stack Exchange",
            "name": "Satisfied user",
            "reviewRating": {
                "@type": "Rating",
                "bestRating": "5",
                "ratingValue": "5",
                "worstRating": "1"
            }
        }
    ]
}

Answer 2

Yes, that makes perfect sense. I'm seeing JSON-LD? I have an example I've been working on using microdata that looks something like:

<div itemscope itemtype="http://schema.org/Review">
    <a itemprop="url" href="could be link to purchase point?"><div itemprop="name"><strong>Some Band / Some new album</strong></div></a>
    <div itemprop="description">brand new country-western album</div>
    <div itemprop="reviewBody">this is really good</div>
    <div itemprop="author" itemscope itemtype="http://schema.org/Person">
        Written by: <span itemprop="name">reviewer Ari</span></div> ##no need to dive into FOAF-related stuff for now
    <div><meta itemprop="datePublished" content="2015-11-30">Date published: 11/30/2015</div>
    <div itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating"><meta itemprop="worstRating" content="0"><span itemprop="ratingValue">4</span> / <span   itemprop="bestRating">5</span> stars</div>

    <div itemscope itemtype="http://schema.org/MusicAlbum">
        <div itemprop="name"> King of Limbs 
            <meta content="Alt/Punk" itemprop="genre" /></div>
        <div itemprop="byArtist" itemscope itemtype="http://schema.org/MusicGroup">
            <span itemprop="name">Radiohead</span></div>
    </div>
</div>
