Over the DAWG's lifetime (and since publication of the SPARQL 
Recommendations in January), there have been many important features 
that have been discussed but did not get included in the SPARQL 

I -- and many others -- hope that many of these topics will be addressed 
by a future working group, though there are no concrete plans for such a 
group at this time.

In the interest of cataloging these extensions and encouraging SPARQL 
developers to seek interoperable implementations of SPARQL extensions, 
I've created:


That page links to individual pages for (currently) 13 categories of 
SPARQL extensions. Each of those pages, in turn, discusses the relevant 
type of SPARQL extension and attempts to provide links to research, 
discussion, and implementations of the extension.

I also plan to use this list to help encourage user- and 
implementor-driven discussion of these extensions over the coming 
months. Again, the goal is to allow SPARQL users to make known what 
features are most important to them and also to allow implementations to 
seek common syntaxes and semantics for SPARQL extensions. (All of this, 
in the end, should help a future working group charter a new version of 
SPARQL and produce a specification that allows for interoperable SPARQL 
v2 implementations.)

It's a wiki. Please add references that are not there, new topics, or 
discussions of existing topics. (I've tried to reuse existing ESW Wiki 
pages for some topics that already had discussion.)

I'm CCing this to public-rdf-dawg-comments@w3.org, but will not send 
future discussion of SPARQL extensions to that list. Please use 
public-sparql-dev@w3.org for discussion of these extensions.
