Dear WG,

we have worked on a new language currently called

     LDOM - Linked Data Object Model

which is primarily based on SPIN, Resource Shapes and ShEx. Like SPIN, 
this new language can also be used in conjunction with RDF Schema and 
OWL, e.g. to extend existing ontologies with closed world constraint 
declarations.

I started a "Primer"

     http://spinrdf.org/ldomprimer.html

which was already reviewed by several people in and outside of 
TopQuadrant, with quite encouraging feedback. There is also a very rough 
starting point for a document about the mapping between LDOM and OWL

     http://spinrdf.org/ldom-owl.html

The LDOM primer links to a file with all the details of the system 
vocabulary

     http://topbraid.org/examples/ldom.ldom.ttl

and there is an example LDOM file with the usual Rectangle ontology:

     http://topbraid.org/examples/ldomsquare.ldom.ttl

I would like to propose this new language as input to the 
standardization process. It covers all currently listed requirements 
from our wiki. I also have a prototypical implementation of a constraint 
checking engine for LDOM that I could roll out as an open source API and 
as part of a future TopBraid beta. Needless to say there are still many 
open issues and details to discuss.

Any feedback appreciated.

Thanks,
Holger
