I know of one example of work that chose OWL Lite as its support 
target.  It is the
ebXML Registry Profile for OWL v1.5 which is a Committee Specification 
from OASIS.
It is available from
http://www.oasis-open.org/committees/download.php/22611/regrep-owl-profile-v1.5-cd01.zip 

which I think is public and also 
http://xml.coverpages.org/OASIS-regrepOWL-Profile-22611.pdf.
This profile defines a way to extend an ebXML RegRep 3 based repository 
implementation to support
storage of OWL based content and simulate some reasoning on that content.  

It's been some time since I reviewed this specification, but as I 
remember it doesn't really completely
support OWL Lite.  It supports RDFS-style constructs plus OWL constructs 
such as OWL metaproperties
and equivalence axioms (and OWL Lite cardinality restrictions but only 
as necessary conditions).  It does this by
defining a standard extension to ebRIM, the underlying data model for 
the RegRep,  and defining standard
stored procedures associated with elements in the extension.  In this 
way it is similar in spirit to OWL Prime
and RDFS++.  I would think that an OWL Datalog fragment could actually 
be a better fit than OWL Lite.
