Here are some new features: http://altoxml.github.io/documentation/use-cases/shape/ALTO_shape_usecases.html

Should we support these new versions? Are there any use cases at the moment?

Eventually, also recording of glyph positions but not sure if&when.

Both FineReader-XML and hOCR already offer character level encoding. It should be possible to transform either of these two formats to ALTO without loss of information.

Skewed Text and polygons are possible with hOCR, so should be a transformation.

3.0 did not seem to bring many notable changes, so it's probably straightforward to implement hocr-alto3.1

zuphilip added the transformation label
