RE: Image annotation vocabulary

Dear all,

You may also be interested in the Open Annotation work [1], which is
currently up for AC review towards becoming a W3C working group [2][3].  It
is currently one of the largest community groups with 127 participants [4].
 We would welcome participation in the working group, assuming that the
review is successful :)

It uses the W3C Media Fragments for simple rectangular boundaries on
images, and SVG for non-rectangular segments.

Another piece of the image annotation puzzle is IIIF, the International
Image Interoperability[5] Framework, which has two components.  The first
is a URL pattern for interoperably manipulating images (region, size,
rotation, quality and format)[6], and the second an Open Annotation based
description format for building up representations of multi-image objects,
be that many images composited together into a single depiction, or many
single images such as the pages of a book or slides in a slidedeck[7].  The
links below are to the drafts of the next version, which will be finalized
in the next couple of weeks.

Hope that helps,

Rob Sanderson
