This has been a classic case of Cool Hand Luke and a failure to
communicate. Indeed, it happens all of the time in this forum.
David comes from a perspective of usability and user interfaces,
granted with a JS bias. Most all of us have recognized his
genius for quite some time, and he is a leading innovator in such
data presentation.
Kingsley has been a passionate advocate for data connectivity and
overcoming all things "silo". Middleware is his game (and OL's).
Data and manipulating data is his perspective, and we know the
superior infrastructure that his personal and then corporate
commitments to these issues have brought.
Benjamin notes today the difference in perspective. Does it
begin with the user experience, or does it begin with the data?
The answer, of course, is Yes.
David with JSON and MQL and other things FB might be criticized.
As he knows, I have done so personally offline and directly.
Kingsley might be criticized for facile hand-waving at UI and
usability questions; he, too, knows I have made those points
privately.
I truly don't know what our "community" really is or, if indeed,
we even have one. But I do know this:
All of us work on these issues because we believe in them and
have passion. So, I have a simple suggestion:
Keep looking outward. We need to talk and speak to the
"unaffiliated". In that regard, David has the upper hand because
presentation and flash will always be easier to understand for
the non-cognescenti. But, David, you know this too: your job is
easier if the nature of the data and its structure drives your
display.
There are HUGE, HUGE advantages of data driving interfaces and
usability that neither of you are discussing. Let's next turn
our attention there and gain some major wins at no cost.

Kingsley,
Thanks for the resources and the detailed explanation! Looks like all

Thanks for the link, Juan.
Just curious, even if I know SPARQL, how do I (as a new user) know
which properties and types there are in the data? And what URIs to
use for what?
David,
Not speaking for Jaun, but seeking to answer the question you posed.
Our iSPARQL interface takes the view that:
1. You lookup vocabularies and ontologies of interest before
constructing triple patterns since the terms need to come from somewhere
2. You then you use the ontology/vocabulary tree to drag and drop
classes over Subject and Object nodes
3. Do the same thing re. properties by selecting them and dropping
them over the connectors (predicates)
4. Repeat the above until you've completely painted an SPO graph of
what you seek.
BTW - the pattern in steps 2-4 above originated from RDF Author, and
we simply adopted it for SPARQL (following a skype session I had with
Danbri years ago re. the need for SPARQL QBE). Note: RDF Author
allowed you to write Triples directly into RDF information resources
via their URLs. Which means the same UI works fine for SPARUL (writing
to Quad Store via its internal Graph IRI or Web Information Resource
URL).

Hi all,
Admittedly this is somewhat of a tease and shameless
self-promotion :-) but I think there are a few interesting
concepts in the query editor for Freebase that I've been working
on that can be very useful for querying and consuming LOD data
sets:
http://www.freebase.com/app/queryeditor/about
Or maybe I missed it totally--is there anything similar for
writing SPARQL queries over LOD?
Cheers,
David
