One of the reply I could make (and made live to you after presentation
@FOSDEM)---intended pun :-)---is that DDE is not the place for what
you ask. DDE (AFAIU) aims to solve a real problem we have in Debian,
namely the heterogeneity of the:
1) location
2) formats
we use to "publish" data about Debian.
Adding an homogeneity layer which addresses such an heterogeneity is
good per se, but it gets you nowhere nearer having a semantic in some
ontology of Debian data. It is not surprising either. As always happen
with ontologies (and not necessarily only with those of the semantic
web), a clear semantics is mostly useful when correlating data coming
from different origins (say, different distributions, as in your use
case); it is way less useful when staying in the realm of a single
origin, which is exactly our case.
That notwithstanding, I understand that it might be useful and
interesting to move a bit nearer to your goal, but IMO that should be
done outside and as an additional layer on top of DDE.
As a personal suggestion, I think you should care more, in this early
stage, about having the pieces you would need to specify a
semantics. The first of such bits is probably the availability of
unique identifiers that unambiguously identify entities exported via
DDE.
Cheers.
