Incubating at OpenRDF.org is a project called Alibaba.  It is a new 
effort to create a OWL DL ontology called point-of-view that (like 
Fresnel) will describe how RDF data should be displayed in HTML and 
other formats.  It differs from Fresnel in that it will serve as a 
presentation model (written in Java Interfaces) for more structured RDF 
data.  The intention is to complement Fresnel with a more complete and 
structured OWL DL for use when working with structured RDF-OWL data with 
strict display requirements.

By using a presentation model expressed in JavaBeans it allows for a 
host of JSP-like templating languages to be used.  I am currently 
experimenting with Groovy templates and how they can be best used in 
Alibaba. I have also successfully used this presentation model with 
facelets to render interactive XHTML search interfaces using domain 
neutral templates.

The project is just starting up and is a couple months away from a first 
release.  However, if anyone is interested in contributing their time on 
this effort please contact me.  You can find the source code at this 
subversion address:
