Open Annotation Data Model

The aim of the current wiki-page is to show that annotations and related structures defined by DASISH xsd schema can be presented in "Open Annotation Data Model". Description of the current Open Annotation requirements can be found at ​http://www.openannotation.org/spec/core/.

In the current page we refer to several images which are open-annotation representations of DASISH xml examples. The reader is encouraged to consult these images while reading the text.

Target Sources

Single target sources are represented as instances of oa:SpecificResource.

Multiple target sources are represented as instances of oa:Composite. Each of oa:item of the composite is either an instance of oa:SpecificResource or oa:Composite.

Bodies

An annotation body in DASISH can be any correct xml. A generic way to present such bodies in "Open Annotation" is to consider a body, which (typically) has attributes and elements, as instances of oa:Composite. Any element and any attribute of the body becomes an oa:item of the body. If an element has sub-elements, it is an instance of oa:composite as well, etc. An attribute or an element with now sub-elements has one of the dctypes and one of the dc:formtats, and possibly additional relevant properties, such as cnt:chars for text values.

Headlines

Any DASISH annotation contains a text element called headline. There is no direct way to represent such a headline in Open Annotation Data Model. In DASISH presentation it is an oa:item of a "big" body, called SuperBody which is an instance of oa:Composite. Another item of SuperBody is the actual body of the annotation.
