Improve Metadata/Properties for DAISY 2.02 output
We've recently begun testing HABC as a replacement for our current DAISY 2.02 production suite and workflow. During our testing we've noticed that the resulting output does not initially pass DAISY 2.02 validation using the industry standard tool (https://code.google.com/archive/p/daisytools/). Two small additions/modifications to the metadata creation seem to be necessary.
ncc:multimediaType needs the content value of "audioNCC" in addition to the other content values.
ncc:sourceEdition is only a recommended field per the specification, but it seems to throw a warning in the validation tool when it is not included.
By modifying the ncc.html output from HABC to include the above changes, I was able to produce a DAISY 2.02 title with no errors in the validator.
if you set “Multimedia Type” in “Properties” to “Audio, TOC” the output will set “ncc:multimediaType” to “audioNCC”.
Support for ncc:sourceEdition will be added in the next update (Probably build 2236).
