Additional metadata for CD-Extra discs #39

Open bitsgalore opened 7 years ago

bitsgalore commented 7 years ago

Since an ISO from a CD-Extra disc needs more work to read, we need to flag these in the metadata.

TODO here:

  1. Embed cd-info output in METS as carrier-level metadata
  2. Add field that identifies carrier as CD-Extra (but where?)
  3. Add field for start sector of data session (from cd-info output) (but where?)

Addition: note that the partition_offset field in IsoBuster's DFXML output also contains info on the start offset of the data session:

<ftype_str>JOLIET</ftype_str>
    <partition_offset>44886016</partition_offset>

(Dividing this by 2048 gives the sector offset as reported by cd-info)

1 + 3 done. TODO: 2 (add field that identifies carrier as CD-Extra )

bitsgalore commented 6 years ago

If we get rid of the carrierType fields, see:

https://github.com/KBNLresearch/iromlab/issues/66

and:

https://github.com/KBNLresearch/omSipCreator/issues/54

In that case we could use something like this in structMap (based on cd-info output):

<mets:div TYPE="cd-extra" ORDER="3" ADMID="digiprovMD_3 techMD_48">
