// "caption": "In every karaoke there are at least 2 voices: a text and a choir"

// Title, Text and Media are not mandatory.
// If some are not present, the createUpdate function will skip them
//
// Note that the Date is required, but its format is up to the user
//
// All the media elements require an alt description.
// This is for accessibility. It's a really good practice to provide quality alt text
// and we must pay attention to this.
