Consider adding creation of annotations from ALTO to list
This is currently in the newspapers implementation guide to be published soon.
@glenrobson (IIIF), Cliff Wulfman (Princeton), and Peter Binkley (Alberta) have sample code to convert ALTO to annotations; adding these references to the IIIF Newspaper Implementation Guide. Consider adding to IIIF-Awesome and then have newspaper implementation guide link to IIIF-awesome.
Latest is that they're still working on making these resources available and getting permission from folks.
There is this XSL example which converts from ALTO to annotations:
