26.9. Configuring annotation icons

26.9.1. User-definable icons by Annotation type (aka "dynamic icons")

The icon used to mark the location of an annotation within an annotated document may be changed by

the user. The icon that denotes an annotation is chosen as a property of the annotation type. By including

an RDF property of each annotation type you wish to use, you select the icon associated with annotations

of that type.

The sample configuration associates the following icons:

The property name for adding annotation icons is http://www.w3.org/2001/10/typeIcon#usesIcon. For

instance, to specify an icon named file:///home/question-icon.jpg for annotations that have type

http://www.w3.org/2000/10/annotationType#Question you would enter the following RDF/XML into a

file that Amaya reads at startup is:

<rdf:RDF

xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

xmlns:i = "http://www.w3.org/2001/10/typeIcon#">

<rdf:Description rdf:about="http://www.w3.org/2000/10/annotationType#Question">

<i:usesIcon rdf:resource="file:///home/question-icon.jpg" />

</rdf:Description>

</rdf:RDF>

The simplest way to get such RDF loaded into Amaya at startup is to include the file in the config/

annot.schemas file in the Amaya program directory. In order to preserve this file so that it will not be

overwritten when you install a new version of Amaya, you should copy the config/annot.schemas file

into your personal AmayaHome directory.

You may list as many RDF files as you want in annot.schemas. See the comments in the file included

in the Amaya kit for more details.

A sample file named typeIcon.rdf declares unique icons for each annotation type declared in the

http://www.w3.org/2000/10/annotationType# namespace. To experiment with user-defined icons, it may

be easiest to copy this typeIcon.rdf into another directory and modify it. Copy annot.schemas to

your AmayaHome directory and change the line near the end to point to your revised icon definition file.

Amaya supports JPEG, PNG, and GIF bitmap graphics formats for icon images. The icon URI may only

be a file: URI; that is, the icon must appear in a local or mounted directory to Amaya. Two special forms

of non-file: URIs are supported. If the file path name starts with $THOTDIR or $APP_HOME then the

corresponding Amaya installation directory or personal Amaya home directory is substituted into the

pathname.
