h1. OAC Representation
We use the [Open Annotation Collaboration (OAC)] (OAC) ontology to represent image annotations.
- the target is an [oac:ConstrainedTarget|http://www.openannotation.org/spec/beta/#DM_Constraint] that uses:
-- [cnt:ContentAsText|http://www.openannotation.org/spec/beta/index.html#DM_Constraint_Inline] (Inline Constraint) to embed the SVG info in RDF
-- We use an [Image Fragment|http://www.openannotation.org/spec/beta/#DM_Frag_Media] (#xywh) to associate a [#View Configuration] with the annotation.
-- The SvgConstraint is given in absolute image coordinates, even for deep-zoom images, no matter what the View Configuration is
- the body is an oac:Body and includes the same properties as for [Data Annotation|Open Annotation Collaboration (OAC)#RS Data Annotation in OAC]
-- if a reply is made, it is attached to the same oac:ConstrainedTarget and has a link rso:reply_to pointing to the original annotation
