8. iXML Production Recorder Metadata

8.1. Notes

iXML allows an XML document to be embedded in a WAV file.

The iXML website recommends a schema for recorder information but there is no official DTD and vendors mostly do their own thing, apart from hitting a few key xpaths. iXML is used by most location/production recorders to save slating information, timecode and sync points in a reliable way.

iXML is also used to link “families” of WAV files together, so WAV files recorded simultaneously or contiguously can be related by a receiving client.

print("iXML Project:", info.ixml.project)
print("iXML Scene:", info.ixml.scene)
print("iXML Take:", info.ixml.take)
print("iXML Tape:", info.ixml.tape)
print("iXML File Family Name:", info.ixml.family_name)
print("iXML File Family UID:", info.ixml.family_uid)

Result:

iXML Project: BMH
iXML Scene: A101
iXML Take: 1
iXML Tape: 18Y12M31
iXML File Family Name: None
iXML File Family UID: USSDVGR1112089007124001008206300
