 ** [metadata](#API_amazon-q-connect_UpdateContent_RequestSyntax) **   <a name="connect-amazon-q-connect_UpdateContent-request-metadata"></a>
A key/value map to store attributes without affecting tagging or recommendations. For example, when synchronizing data between an external system and Amazon Q in Connect, you can store an external version identifier as metadata to utilize for determining drift.

The URI for the article. If the knowledge base has a templateUri, setting this argument overrides it for this piece of content. To remove an existing `overrideLinkOurUri`, exclude this argument and set `removeOverrideLinkOutUri` to true.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 4096.  
Required: No

 ** [removeOverrideLinkOutUri](#API_amazon-q-connect_UpdateContent_RequestSyntax) **   <a name="connect-amazon-q-connect_UpdateContent-request-removeOverrideLinkOutUri"></a>
