SPARQL and Subqueries

 

 

 

 

 

Colleagues

 

For a second iteration of SPARQL, we propose aggregation and subqueries.

 

There is a blog post at 

 

http://virtuoso.openlinksw.com/blog/

 

where I present a sample of an extension for subqueries and aggregates.

There is also a syntax sugar for abbreviating chains of joins.

 

Aside these, there is the issue of discovery and description.  We will
implement a little database statistics  graph for distributed query
optimization and data discovery. More on this later.
