[VK] The key issues we may want to explore in the context of a well defined use
case (which hopefully mirrors the real world to a significant extent) are:
1. How do we decide when to use OWA vs CWA? 
2. Is it possible to look at the data characteristics to determine that? For
instance, Chintan's lab example where negative statements are explicitly
asserted.
3. Use of appropriate technology for the same. For instance, we may want to
articulate the pros and cons of using a SQL querying based approach as opposed
to an OWL classification based approach.
