Re: best practice relation for linking to image/machine-opaque docs? biomedical use case

Hi Michael,

The default is assumed to be pixels.  Thanks very much for the suggestion regarding GeIML.   

Subclasses of AO's Selector class have been worked through in some detail for annotating text, but have not received comparably detailed attention for images.

This is something we are hoping to do in the future, particularly for biomedical imaging.  Collaborators interested in working with us on this topic are welcome. 

Kind regards,

Tim
