YouTube content ratings
A <content_rating> tag provides information that can be used to categorize the content of a video in the absence of an official rating, such as a Motion Picture Association of America (MPAA) rating. You can also use a <content_rating> tag to indicate that a music video contains explicit lyrics. YouTube could use that information to display a badge on the video's watch page or in search results.
The <content_rating> tag is a child of the <feed> tag. You then define a relationship to associate the content rating with one or more videos.
A YouTube content rating contains a series of values that categorize the content of a video several categories. Each category has three options that indicate the level of mature content. To provide a YouTube rating for a video, select one value for each of the categories and separate the values with spaces. For details about the rating options, see YouTube content rating.

<content_rating system="youtube"
tag="family">L0 S0 N0 D0 V0 F0
<content_rating system="youtube"
tag="very bad for kids">L2 S2 N2 D2 V2 F0
<relationship>
<item path="/feed/content_rating[@tag='family']"/>
<related_item path="/external/video[@id='VIDEO_ID_1_']"/>
<related_item path="/external/video[@id='VIDEO_ID_2_']"/>
<relationship>
<item path="/feed/content_rating[@tag='very bad for kids']"/>

The XML snippet below demonstrates how to indicate that an existing music video contains explicit lyrics. The <content_rating> could also be associated with the video when the video is created. Note that a video must be in the Music video genre to display an "Explicit Lyrics" badge.
<content_rating system='lyrics' rating='explicit'/>
<relationship>
<item path="/external/video[@id='VIDEO_ID_1_']"/>
<related_item path="/feed/content_rating[1]"/>
