Collect metadata

Optimizely Content Recommendations uses metadata for the following two main purposes:

• Within flows as a way to categorize content, based on common metadata attributes. See Setting up sections and flows.
• Within rendering to specify what elements to display for each content item recommended.

Optimizely recommends the following metadata fields and will support the majority of content recommendation use cases:

• Title – Title should appear under the meta property og:title in the follow format.
  XML

  <meta property="og:title" content="value" />
  <meta property="og:title" 
        content="High yield spreads aren't as narrow 
                 as they may first appear" />
  

• Description – Description should appear under the meta property og:description in the following format.
  XML

  <meta property="og:description" content="value" />
  <meta property="og:description" 
        content="While high yield bonds’ yield to maturity
                 may be close to historic lows,
                 credit spreads themselves are not, 
                 particularly when adjusted for favorable
                 changes in credit quality and duration." />
  

• Image – Image should appear under the meta property og:image in the following format.
  XML

  <meta property="og:image" content="value" />
  <meta property="og:image" 
        content="https://www.episerver.com/globalassets/09.-tests/testimagesvideo/opengraph_episerver.jpg" />
  

• Published date – Published date should appear under the meta property article:published_time in the exact format below.
  XML

  <meta property="article:published_time" content="value" />
  <meta property="article:published_time" content="2019-10-18T15:19:00.000-04:00" />
  

• Article category – Article category should appear under the meta property article:category in the following format.
  XML

  <meta property="article:category" content="value" />
  <meta property="article:category" content="Fixed-Income Insights" />
  

Additional metadata fields are also supported using the custom namespace (idio:) to pass information. For example:

<meta property="idio:custom_variable" content="value"/>

If you have multiple values for a metadata item, Content recommendations collects them all. For example:

<meta property="article:tag" content="Tag One" />
<meta property="article:tag" content="Tag Two" />
<meta property="article:tag" content="Tag Three" />
