- Description
- RealPlayer created RA for audio streaming. It makes use of various audio codecs from those that deliver high-fidelity sounds to those that record low bitrate audio data. Radio stations mainly used it for online streaming, but current formats have overthrown it.
- OPML (Outline Processor Markup Language) is an XML-based format used to exchange outline-structured information. It is most commonly used to share lists of web feed subscriptions (such as RSS or Atom feeds) between feed readers and aggregators.
