RealAudio .ram metadata files are very simple files that hold references to audio sources. They consist of one line of plain text: a URL. This can be a relative or absolute [[HTTP]] URL, but for streaming services this may use the [[Real-Time Streaming Protocol]] or the older [[Progressive Networks Media]] protocol.
