It turned out to be quit a simple change. Add an additional field to the
org.dspace.app.xmlui.configuration.Theme object to hold the metadata field
and value to match,
modify org.dspace.app.xmlui.configuration.XMLUIConfiguration to include the
new Theme object field in its work, and
modify org.dspace.app.xmlui.cocoon.ThemeMatcher to add matching of the
metadata field and its value:
if (rule.hasMetadata()) {
if (dso == null) {
continue;
}
String[] parts = rule.getMetadata().split("[\\=]");
if (parts.length != 2) {
continue;
}
Metadatum[] md = dso.getMetadataByMetadataString(parts[0]);
if (md.length < 1) {
continue;
}
if (!md[0].value.equals(parts[1])) {
continue;
}
}
So now to have a particular theme for an item with a specific dc.type all I
do is add the following line(s) to the xmlui.xconf file:
<theme name="New Theme" metadata="dc.type=<some dc.type>" path="<some theme
path>"/>
It seems to work. Thanks guys.
