How do I get the link field to rewrite itself in Velocity?

Instead of:
<meta name="thumbnail" content="http://www.union.edu/admissions/profiles/img/feature-tile/live-learn-minerva.png" /> It's rendering:
<meta name="thumbnail" content="site://reboot/admissions/profiles/img/feature-tile/live-learn-minerva.png" />

Here's my Velocity code and attached is my page XML.

#set ($thumbnail = $_XPathTool.selectSingleNode($contentRoot, '//system-page/system-data-structure/header/thumbnail/link').value'))
#if ($thumbnail)
    <meta name="thumbnail" content="${thumbnail}" />
#end

I'm running Cascade 7.12.4.

   Erik,

   Try something like this:

   #if ($thumbnail)
       #set( $thumbnail = "[system-asset]" + $thumbnail + "[/system-asset]" )
       <meta name="thumbnail" content="${thumbnail}" />
   #end

   Hi Erik,

   To echo Wing's suggestion, here are a few alternatives, the key is to use the [system-asset] pseudo tag:

   #if ($thumbnail)
       #set( $thumbnail = "[system-asset]${thumbnail}[/system-asset]" )
       <meta name="thumbnail" content="${thumbnail}" />
   #end
   

   #if ($thumbnail)
       <meta name="thumbnail" content="[system-asset]${thumbnail}[/system-asset]" />
   #end
   

   Please let me know if you have any questions.

   Thanks!

   Ryan,

   I tried to document this example in my site. But I had a very hard time dealing with the string literal "[system-asset]". I even turned all punctuations to unicode characters. It still did not work. Right now I just added a space between "[" and "s". How do I escape this string so that it can be displayed on a page (the string is in fact in the WYSIWYG)?

   By the way, I am very happy that the Edit button is back.

   Hi Wing,

   Although not ideal, placing a space within the tag is definitely the best way to go. If you wish to avoid the space from appearing on the page (and when copying), we use the following on our KB:

   [<!-- -->system-asset]/path[<!-- -->/system-asset]
   

   The comment and space will cause the pseudo tag to be skipped, but because we the space is commented out, it will not appear to the user.

   Please let me know if you have any questions.

   Thanks!

   Ryan,

   By using a comment containing a space? What a funny way! But thank you for the info.

   I know, right. So unconventional, but it works!

   I'm going to go ahead and close this discussion, please feel free to comment or reply to re-open if you have any additional questions.

   Have a great day!

   Thanks for the tips, guys. I reviewed the knowledge base and see that the [system-asset] tags are needed because Google's <meta content=".."/> tag isn't one of the recognized attributes tracked automatically.

   But I noticed Velocity is omitted from the list of assets that support "System-asset" and wanted to point that out.

   Thank you for notifying us of the incorrect information, Erik. I went ahead and updated the content to simply Formats so it includes both types.

   I'm going to go ahead and close this discussion, please feel free to comment or reply to re-open if you have any additional questions.
