iXML

iXML is an <a href="/facts/Open_standard/RGvhGQVI">open standard</a> for the inclusion of location sound metadata in Broadcast Wave audio files, video files and also IP video and audio streams. This includes things like Scene, Take and Notes information.
It is the result of extended discussions between the various manufacturers of Field recorders and editing systems. It is designed to standardise the exchange of metadata between these systems.
The iXML specification describes an <a href="/facts/WAV/ptUfKleW">WAV</a> <a href="/facts/Resource_Interchange_File_Format/G48SB1nh">RIFF</a> chunk in <a href="/facts/Broadcast_Wave_Format/SjJmC73m">BWF</a> files which contains standard <a href="/facts/XML/clNgUfWk">XML</a> data following the iXML specification. It also introduces the concept of using iXML in IP video streams such as <a href="/facts/Network_Device_Interface/ttw8vDlg">NDI</a>
Prior to the development of the iXML specification, the film and TV industry relied on the BWF bext description chunk which was used differently by many vendors to roughly encode some small metadata, but was invariably undefined, with too little space for full information. Whilst many systems tried to read what they could from the bext data, because of no specification and limited space, bext usefulness was limited.
