-Annotations of images have a "regions" member, specifying a list of regions on the image. The region definitions are based on the [[http://geojson.org/geojson-spec.html|GeoJSON format]] and the [[http://www.w3.org/TR/SVG/shapes.html|SVG shape definitions]].

+Annotations of images have a "shapes" member, specifying a list of regions on the image. The region definitions are based on the [[http://geojson.org/geojson-spec.html|GeoJSON format]] and the [[http://www.w3.org/TR/SVG/shapes.html|SVG shape definitions]]. 
 
 The possible region forms are
-  * point
-  * line
-  * rectangle
-  * polygon (not yet implemented)
-  * circle (not yet implemented)
+  * point (x, y)
+  * rectangle (x, y, w, h)
+  * polygon (coordinates: [list of x,y])
+  * linestring (coordinates: [list of x,y])
 
-Coordinates and coordinate units are specified in a "geometry" member. 
+Coordinates are specified in a "geometry" member. Coordinate units are specified in a "units" member.
 
 The coordinate unit "fraction" means that each coordinate is specified as a decimal fraction (float 0 <= x <= 1) of the image side length, e.g. x=0.03 means that x is at 3% of the total image width.
