Hi Richard
from my point of view the DOM-like approach does exists yet, and it's
by SPARQL and LDpath. What are them lacking? Do you feel there should
be an object-oriented approach? As for the Jena model or Sesame
internal Graph representation? If this is the case it could be
interesting from my point of view an approach similar to the current
implmentation of the Sail interface.
Alfredo,
I think a query language on its own isn't enough. I would like to see
an environment in which I can create an in-memory graph, load it with
one or more graphs and/or query results, create, delete and edit graph
nodes and triples within it, query it, and serialize all or part of the
result to any of the popular serialization formats, plus (X)HTML,
ideally using a tool as powerful as XSLT. :-)
Looking up LDPath I came across Marmotta [1], which seems rather closer
to what I have in mind.

Hi,
I'm sure this has been discussed many times and/or ages ago, but I
am struck by the absence of a DOM-like W3C framework for RDF. By
this, I mean "an application programming interface (API) for [RDF
graphs]", which will be "a standard programming interface that can
be used in a wide variety of environments and applications. The
[RDF] DOM is designed to be used with any programming language".
(Quotes taken from [1])
A quick search turns up a number of PHP-based libraries, and the
odd one for javascript, Delphi, Python and Ruby, but as far as I
can see there is little, or no, commonality of approach or
functionality amongst these offerings. This means that a
programmer (a) has to decide which of these widely varying
approaches to adopt, (b) only gets whatever documentation each
chooses to provide and (c) is faced with a complete rewrite,
should they decide to switch RDF platform.
Might this situation be a significant factor in the slow take-up
of RDF by mainstream developers?
