TODO(leonid) Deprecate these Authors string for front end.

the URL of the reference page (About this book)

metadata_cover_exists will be set if there's a metadata-provided cover thumbnail. the thumbnail will be used for scanless books or when a scanned book is in metadata-only view.

patent-specific fields. ALL DEPRECATED, moved into PatentSpecific group, above.

Percent rights granted by publisher. This should only be set, and definitely should only be considered, if source_type == BoundVolumeSource::PUBLISHER. '0' may mean we have no info on publisher rights so we have to just assume 0%. Deprecated as this is taken into account by viewability

The size (in pixels) of the metadata cover image.

DEPRECATED! Being replaced in favor of viewability, below. geo restrict info (from OceanRights::geo_restrict) In CAv2: geo restrict info (from ocean::VolumeImprintRights::geo_restrict)

printed page number (OceanPrintedPageNumber; from OceanPageInfoMap::Page::printed_page_number)

Bibkey to be used as part of the URL (to make them persistent in some sense). This is obtained by doing a GetURLKey() on the bibdata which returns the main bibkey associated with the volume based on priority. This is parseable into an OceanVolumeBibKey (ocean/metadata/bibkeys.h) Note: This should ideally be a required field longer term but for now keeping it optional for compatibility. In case of this being absent, we don't include the key in the URL (just use volumeId as before). Note: For content type books, this key is supplemented by other bibkeys for this volumes(the field is aux_bibkeys)

pageid of the page (OceanTypes::PageIdType)

List of locales for which this book can be bought from a publisher, and read as a Google eBook. Each locale is a lowercase, two-letter country-code (eg "ca"), and is copied from PublisherGrantability.Locale.locale, defined in ocean/data/docinfo/volume_viewability.proto.

Title string for front end.

using_actual_cover will be set if we are using the actual cover of the book (instead of the table of content, etc.). This is particularly useful to identify books where we inserted a generated cover via Coverups.
