Details

This is used when requesting image metadata from a ForiegnApiRepo. Media handlers that need to have versioned metadata should add an element to the end of the version array of the form 'handler_name=version'. Most media handlers won't need to do this unless they broke backwards compatibility with a previous version of the media handler metadata output.

• &$version: Array of version strings
