All the sights I've uploaded to ask you to supply the meta data by entering it in a title, description, author bio field etc. Some want it as a spreadsheet.
By setting the ID
<dc:identifier opf:scheme="ISBN">123-4-5678-9012-3</dc:identifier> you can search by ISBN - however, I've had mixed results in validation and am unsure if it's me or not.
I've not seen
<dc:creator opf:role="aut" opf:file-as="Name, Author">Author Name</dc:creator> and can only guess it's old. Doesn't it validate?
For the blurb I creat a text file that has the following information in it so I can cut and paste into the different sites.
- Title
- Subtitle
- Author
- Author 2
- Publisher
- BISAC Code and descriptions
- Publish Date
- Pages (print)
- Search metadata (They only allow 7 items usually)
- Description with paragraph breaks.
- Author Bio
- Author 2 Bio
- Reviews
