Initialisation of the EPUB 3.4 Annotations TF

Dear all, 

We'll start studying annotations for EPUB in sunny Sophia Antipolis in a few weeks. 
Before that, I would like to know who in this group is interested in participating in this work and later integrating the import/export of annotations in their reading systems. 

We'll also look at potential Invited Experts in this work (who could become W3C members as an alternative).
I'll contact readwise.io <http://readwise.io/> and hypothes.is <http://hypothes.is/>, both deeply involved in this annotation feature, in case they are interested. I believe Colibrio will also be interested. If you know of other companies that have developed an import/export feature for annotations, please reply with their names. 
One of the EDRLab members, FBReader, has an export feature for annotations and may give some advice. 

For reference, the specification of Readium Annotations <https://github.com/readium/annotations> is already integrated into Thorium Reader 3.1. An appendix page <https://github.com/readium/annotations/blob/main/Selectors.md> contains complementary selectors, i.e. ideas that have not been incorporated into Thorium so far; this includes EPUB CFI.

Best regards
