Hi. Florian and All.
Sorry for late reply.

Thanks for Florian, two properties mapping were wrong.

I added inline comments

That's correct. We have to revise this mapping as below.
rss/channel/item/media:group/media:rating

@Thierry: Could you update this in the ontology REC spec?

Current mapping table is correct for above three items (compression,
duration, format).


> publisher -> complete different XPath

That's right. This is similar mistake with earlier one. I think I was
confused between media:content and media:group for some mapping.

Therefore this mapping should be changed as below.
rss/channel/item/media:group/media:credit[@role='uploader']

@Thierry: Please update this in the REC spec.

best regards,
Wonsuk.
