A TLO, Teaching and Learning Object is a Drupal Content Type we created. It has 4 fields.
Title Field: This is linked to the node itself. It should be kept short.
Caption Field: This appears below the TLO, and should be a short description
Body Field: This only appears on the TLO node, not when it is embedded. You can make this as detailed as you want. You can embed additional media elements into it, even other TLOs.
TLO File field: This can be uploaded to the library, or taken from web services like You Tube
