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.

Ok Guys I'm gonna try the following and comments are welcome.
1) I'm gonna add code in org.dspace.app.xmlui.configuration.Theme that
stores an additional tag (similar to handle=) called 'metadata' with
appropriate methods hasMetadata() etc.
2) In ThemeMatcher I add an additional section testing if if
(rule.hasMetadata()
dso.getMetadata(...))
and so on and so forth

I've done this in the past it's just that it tends to get messy the more

Another route to go would be to use a single theme, and then have XSL
logic that changes the behavior of item-view, depending on that metadata
value. In my theme I've been changing the display behavior depending on the
mimetype of the bitstreams (audio, video, document), as well as metadata
values, ex ds.firstpage.side=left [2] alters the bookreader to have a the
first page of a scanned book display on the left side of a bookreader spine.

I'm longing to add a Collection Configuration page, where you could add
some configuration values to a collection, and then have the theme change
actions based on that. i.e. collection.map.show = true

John,
Seems sensible, what would be ideal is if we could arrive at some sort
of language for the field that would allow for matching on other criteria.
Some days I wonder why this isn't just in the cocoon sitemap,
xmlui.xconf is very limiting and unwieldy. Alternatively, making the
matcher into Service and giving it a spring based configuration with
matching rules would also be extremely extensible without needing special
xmlui.xconf parsing code that you'd need to extend/alter to create your
own config attributes.

So if I add some rule patterns to the xmlui.xconf (regex=? section)
that dont break the existing ones, and add code to ThemeMatcher (lines 105
to 120+) that use the uri to instantiate the dspace object and find some
metadata and match to the rule pattern (similar to the checking handles
code) then I should be good to go.

John,
You could add a theme match on Item handle. We have overridden
ThemeMatcher in other projects and extended it with additional support
for
features such as requested domain name. I can see it feasible to extend
it
to support checking for specific metadata fields in the 5.x DSpaceObject
metadata.

Hi All, Can anyone say if it is possible within DSpace 5.x codebase
to install a different xmlui theme based on a dc.type similar to what is
done to install a theme per collection or community, or if not then how
easy it would be for me to add a hack or code to implement such a beast.
