METS Encoding

Chapter Markers

To set chapter markers, use <mets:area> with type TIME on the physical structure node and link it from a leaf logical structure node. Only the begin is used.

<mets:div ID="PHYS_0002" ORDER="2" TYPE="track">
  <mets:fptr>
    <mets:area FILEID="FILE_0000_DEFAULT" BEGIN="00:06:04" BETYPE="TIME" />
  </mets:fptr>
</mets:div>
Copied!

Fractional timecodes (e.g., 00:06:04.5) may be used.

Waveform

To link preprocessed audio waveform data, use the WAVEFORM use groups (configurable in useGroupsWaveform). See the section on the waveform component for information on how to generate the data.

<mets:fileGrp USE="WAVEFORM">
  <mets:file ID="FILE_0000_WAVEFORM" MIMETYPE="application/vnd.kitodo.audiowaveform">
    <mets:FLocat LOCTYPE="URL" xlink:href="https://www.example.com/waveform.dat"/>
  </mets:file>
</mets:fileGrp>
Copied!

Note that the custom MIME type must be specified. Currently, data generated by the audiowaveform tool is supported. Other formats may become supported in the future.

Multiple Sources

Multiple alternative sources may be referenced by linking more than one file to a <mets:div>. They are tried in the order of the <mets:fptr>.

<mets:div ID="PHYS_0001" ORDER="1" TYPE="track">
  <mets:fptr>
    <mets:area FILEID="FILE_0000_DEFAULT_MPD" BEGIN="00:00:00" BETYPE="TIME" />
  </mets:fptr>
  <mets:fptr>
    <mets:area FILEID="FILE_0000_DEFAULT_HLS" BEGIN="00:00:00" BETYPE="TIME" />
  </mets:fptr>
  <mets:fptr>
    <mets:area FILEID="FILE_0000_DEFAULT_MP4" BEGIN="00:00:00" BETYPE="TIME" />
  </mets:fptr>
</mets:div>
