For any other readers regarding imprint and top level publishing name:

Reading more, it looks like the unique section of the publishing name in the ISBN will point to the top level publishing name, or to an imprint, if an imprint was selected in Bowker when the ISBN was selected for that title.

In other words, from my understanding, when Amazon (or a library or any entity) queries the Bowker (or ISBN) database, as long as the publisher listed in the metadata of the ebook matches the one selected in your Bowker acct, it should validate. Meaning, the dc:publisher metadata should be the imprint (vs the top level publisher), when that's applicable.

If someone more experienced knows better, please correct me.

Once I get this book up, if I get an error due to this assumption/understanding, I will come back and correct this myself. But I won't be uploading the book for a couple weeks yet.
