Hmmm (speaking as an RDF advocate) ... that seems like an odd reason for
Much of the value of RDF is, I would say, as means to exchange information
*between* programs rather than for internal structuring of data. An
RDF-graph-based interface to data provides for some uniformity of access
and processing that can be useful. In my own work, I have at least two
different internal representations for RDF data (neither of which have been
designed for efficiency).
