Two days ago the discussion touched this interesting point. I
do not
know how to answer this question.
Ideas?
We need to start consuming linked data and making reall mashup
applications powered by linked data. A couple of days I just
mentioned the link for SQUIN: http://squin.sourceforge.net/
The idea of SQUIN came out of ISWC08 with Olaf Hartig. The
objective is to make LOD accesible easily to web2.0 app
developers. We envision adding an "S" compoment to the LAMP stack.
This will allow people to easily query LOD from their own server.
We should have a demo ready in the next couple of weeks.
We believe that this is something needed to actually start using
LOD and making it accesible to everybody.
How does SQIUN differ to a typical HTTP SPARQL endpoint? So far it
accepts a "query" parameter as a SPARQL select statement and executes
the parameter on (some configured?) SPARQL endpoints from looking at
the single sourcefile I could find [1]. Having said that, I have been
holding off getting my bio2rdf server to actually process rdf but it
doesn't look so hard now. (The bio2rdf server is actually more generic
than just biology or even bio2rdf but it is still named that in
response to its origins. And in contrast to SQUIN it focuses on
CONSTRUCT queries rather than SELECT)
On the subject of mashups I have been thinking in the last few days of
combining the bio2rdf server with the pipes.deri.org
<http://pipes.deri.org> interface for mashups, as some fairly
sophisticated mashups can be done on pipes.deri.org
<http://pipes.deri.org>, but a lot of the generic queries seem to be
better handled at the client level where people can control with
configurations what endpoints are used and have backups if a
particular endpoint fails.
Cheers,

Peter,
Has anything happened re. cross-linking the data across bio2rdf.org and
dbpedia.org?
Sane cross-linking is vital to Linked Data Web oriented Meshups.
Note, there is a distinct difference between a Mashup and a Meshup in my
world view. Mashups are nice looking opaque Web pages that have code
behind them while Meshups are transparent Web pages with Linked Data
behind them (i.e. the data object URIs are accessible to machines). A
Meshup style page is really the Linked Data Web's equivalent of a
traditional DBMS View.
