The wandoc XML regroups the Wanda XML tags devoted to document annotation.
A wandoc document consists of one or several pages, each of which is
represented by an image (allowed formats include gif, tif and jpg).
Within each page, annotations may include:
In order to accomodate user-defined filters and annotations, generic tags <input/>
<output/>, and <annotation/> are introduced. Elements enclosed withing these tags
will be application specific and defined in separate DTDs. See, for instance, the
following annotation DTDs: writer ,
The tag <comment/> however is a generic annotation.
For particular inputs and outputs, see the NICI measurement filter DTD: nicifeat .
The tags <features/> and <wanda_link/> enclose generic types of outputs.
In several data blocks (<page/>, <region/>, <annotation/>, <filter/>, <input/>, and <output/>, links can
be specified to point to a file the content of which
replaces the element <wanda_link/>.
- Textual annotations, such as information about the page content, writer,
pen and writing surface used, type of script and language used.
- Filter declarations corresponding to operations applied to the image
that can either be recomputed on-the-fly, or played back using a cached result.
- Regions, which are user-defined polygons or rectangles
delineating a particular region of interest on the image. Regions may be
recursively defined and are themselves annotated.
