I strongly agree on this with an additional
observation. SPARQL is at base a language. If you propose an
editor for SPARQL then it sounds as if you are proposing a tool
that converts something more user friendly such as a CNL or
simplified NL into a valid SPARQL query. Is this correct?
The focus of this issue is the need to move
from a syntax based construct to a semantic construct. Perhaps
we should add "extensibility" to Tim's "diversity,
heterogeneity, and interoperability".
This is where the *provincial* and a kind of *NIH* have hurt this
component of the Semantic Web stack. Basically, in the SQL realm you
have Query By Example (QBE) tools that enable a variety of user,
integrator, and developer profiles to learn and exploit SQL,
progressively.
In addition to QBE tools you need Report Writers too. Basically, the
loose coupling that ODBC and JDBC deliver to SQL is something that
SPARQL actually matches and exceeds via HTTP URIs. Ironically, this
isn't basic instinct in the Semantic Web community, the tend to want
to "rip and replace" everything with a programmer profile in mind
:-(
End-users, Integrators, Systems Analysts, and Domain Experts need to
be part of the dialog. They also need to be the profile to which
tools are targeted.
