Because I care about METS/ALTO, I didn't want the crickets to win on
this one, but it seems like a very in-the-trenches technical question.
Have you tried the NDNP folks

Subject: [METS] METS/ALTO & ROTATION Question
I have a question is on best practice for describing text rotation when
digitizing a document. I am currently attempting to use METS and ALTO
describe scanned pages from old journals in a small side project.
The plan is to use the ROTATION attribute for TextBlocks that are
capture the text with OCR. The ALTO standard demands that this rotation
described in degrees counter-clockwise, which is fine. However, it
specify if this rotation is FROM "starting orientation" TO "reading
orientation", or FROM "reading orientation" TO "starting orientation".
I am assuming it is best to describe rotation from the way the page
within the actual journal volume to the reading position, but I can't
anything that confirms that this is what other projects do. Or is this
something that is not consistent from one project to the next? My
was that the eventual goal would be for this content to be compatible
other, similar METS/ALTO content, so I'm looking to avoid an obvious
if I can.
So, is there a source for a "best practice" on page rotation, either in
