Nice! I will wait for the client though, thx. Where will the source images
be stored? Labs or Commons? It would be nice if you could somehow make a
client that builds a djvu file locally with the page image and the OCR text
that you can cleanup before putting it into the djvu file. Now it just
seems there are so many hurdles to ws that it's quicker to post pages to
Commons and add the text in the template there.

Hello again.
So, I've set up an OpenOCR instance on Labs that's available for use as a
service. Just call it and point to an image. Example:
*curl -X POST -H "Content-Type: application/json" -d
'{"img_url":"http://bit.ly/ocrimage
<http://bit.ly/ocrimage>","engine":"tesseract"}'
http://openocr.wmflabs.org/ocr <http://openocr.wmflabs.org/ocr>*
should yield:
"You can create local variables for the pipelines within the template by
prefixing the variable name with a “$" sign. Variable names have to be
composed of alphanumeric characters and the underscore. In the example
below I have used a few variations that work for variable names."
If we see evidence of abuse, we might have to protect it with API keys,
but for now, let's AGF. :)
I'm working on something that would be a client of this service, but don't
have a demo yet. Stay tuned! :)

I explored abbyy gx files, the full xml output

running at Internet Archive, and I've been astonished by the amount of data
they contain - they are stored at XCA_Extended detaiI (as documented at
http://www.abbyy-developers.com/en:tech:features:xml ).
Something that wikisource best developers should explore; comparing those
data with the little bit of data into mapped text layer of djvu files is
impressive and should be inspiring.
But they are static data coming from a standard setting... nothing
similar to a service with simple, shared, deep learning features for
difficult and ancient texts. I tried "ancient italian" tesseract dictionary
with very poor results.
So Asaf, I can't wait for good news from you. :-)

Yes, the output is generally good. But as far as I can tell, the
archive's Open Library API does not offer a way to retrieve the OCR output
programmatically, and certainly not for an arbitrary page rather than the
whole item. What I'm working on requires the ability to OCR a single page
on demand.
True.
I've recently met Giovanni, a new (italian) guy who's now working
with
Internet Archive and Open Library.
We discussed about a number of possible parnerships/projects, this is
definitely one to bring it up.
But if we manage to do it directly in the Wikimedia world it's even
better.
