The page defines the "ionofm" RSS namespace used to insert additional metadata into our RSS feeds

Namespace declaration:

xmlns:ionofm="http://iono.fm/rss-namespace-1.0"

Namespace elements

Note that all the elements in this namespace is optional, and that any (or all) of them may be omitted from a response.

Image thumbnails

<ionofm:thumbnail href="http://url.to/thumbnail.png">

The thumbnail element provides a link to a small thumbnail of the related image. This applies to both the RSS <channel> element and it's child <item> elements. It's href attribute must contain a URL pointing to a 256x256 PNG image.

Cover Art

<ionofm:coverart href="http://url.to/coverart.png">

The coverart element provides a link to the art banner if set for content. This applies to both the RSS <channel> element and it's child <item> elements. It's href attribute must contain a URL pointing to a 1500x500 PNG image.

Object live-stream

<ionofm:stream>

The stream element provides links to any live-streams associated with a provider or a channel. It is valid within the RSS <channel> element or within <item> elements.

Child elements of this field is the list of available live-stream formats. Currently supported are:

  • streamname : the name of the live stream, to be used for retrieving other stream related metadata.
  • hls-aac : HLS stream containing AAC encoded audio.
  • ice-mp3 : Icecast stream containing MP3 encoded audio.
  • ice-aac : Icecast stream containing AAC encoded audio.

Each format element can specify up to 3 URL's for the low, medium and high quality version of the stream.

Not all streams support all quality levels! For example, "Community" stream packages only support 2 quality levels.

Example:

<ionofm:stream>
      <ionofm:streamname>stream_identifier</ionofm:streamname>
      <ionofm:hls_aac>
             <ionofm:low src="http://location.to.low.m3u8"/>
             <ionofm:medium src="http://location.to.medium.m3u8"/>
             <ionofm:high src="http://location.to.high.m3u8"/>
      </ionofm:hls_aac>
