that one could navigate through the
entire LOD (e.g. state - state/year - state/year/month -
state/year/month/typeOfProducer -
state/year/month/typeOfProducer/energySource).
4. Any other considerations that I'm overlooking?

I wanted a hands-on session for my lecture on RDF, so I added an interactive
shell to Hyena:
http://2ality.blogspot.com/2010/07/teaching-rdf.html
I'd be interested to know what others use to teach RDF (in a tutorial style).

There might not be anything in it, scientifically, but it would help to sell
RDF to a community that is largely orthogonal to the one that is after RDF +
semantics.

### Hyena
, anything that can be an object
should also be useable as a subject. Of course, that does allow for the view
that both of them should only ever be IRIs, I guess.

The closest I get is the following SPARQL query:
SELECT DISTINCT ?subj ?label
WHERE {
GRAPH ?graph {
?subj ?pred ?obj .
OPTIONAL {
?subj ?labelPred ?label .
FILTER (
(?labelPred = http://www.w3.org/2000/01/rdf-schema#label) #
FILTERs (for faceted navigation
etc.).

Im not sure what you mean by 'stable identity',
It's a slightly (possibly unorthodox) viewpoint I take during RDF editing: With
a container, you can say I will edit the sequence at URI X and be sure that X
stays the same, no matter how you change the elements. With a collection, the
anchor
In contrast to RDF collections (rdf:List), they have a stable identity and
don't use nested resources (=easy to remove). Furthermore, standard RDFS
inferencing can be used to infer membership as the property rdfs:member.
Yet, most RDF vocabularies that I know of use collections and syntaxes
Our goal with the first release of the Fresnel vocabulary in 2006 was to have
more people (beyond us) play with it in different contexts and get feedback
so that the language could be enhanced iteratively. Maybe it is now time to
do such an iteration?
I am working on my own Fresnel 2. The
I think, it would make sense at some point in time to work on Fresnel 2.
My experiences (while implementing editing extensions for Fresnel for Hyena
[1]) were as follows:
- Fresnel works great for editing, with a few extensions. I've found some
things to be too complicated (mainly formats and
This description reminds me of NRL, maybe it is closer to what you need.

Yes. I meant (and want) live access, but would never expect an RDF
schema to provide this. ;-)
Changesets seem very useful for exporting histories.

You were asking about description logic programming; well, OWL 2 RL:

I'm currently reading Hendler's brilliant book Semantic Web for the
Working Ontologist. It really drove home the point that OWL is not a
good fit when using RDF for *data* (names are generally not unique,
open world assumption, ...).
But what is the alternative? For my applications, I have
look at SPIN?
http://spinrdf.org/
That should allow you do do a lot with data without leaving the now
mainstream Semantic Web technology stack (as long as a small
fragment of OWL is sufficient for you).
