The SKUA project, 'Semantic Knowledge Underpinning Astronomy’, will create a distributed architecture of semantically aware RDF stores. (1) This ‘semantic layer’ may be accessed directly by a user in finding and recovering relevant resources, or may be embedded within user-facing applications. Although the system we build will be specialized to astronomy, and proved by its interaction with, and eventual embedding within, the Virtual Observatory, the bulk of the semantic knowledge is localized in the RDF store. (2) This reflects the core design goal that the semantic knowledge could be replaced if desired by the analogous semantic knowledge of a different domain.
"semantically aware" to "semantically-aware, knowledge-sharing" (to
address point 3?)
You might simplify further:
Although the system we build will be specialised to astronomy, and
developed [deployed? tested?] within in the context of the Virtual
Observatory, the bulk of the semantic knowledge [etc]

The UK JISC-funded SKUA project, 'Semantic Knowledge Underpinning Astronomy’, will create a distributed architecture of semantically aware RDF stores. Each store will be populated by users with claims about entities in astronomy research and may include supporting knowledge-bases such as ontologies and controlled vocabularies. SKUA will make it possible to federate these stores such that queries against one will be propagated to a wide range of other stores: federation will be subject to security constraints set by store owners. Although the system and trial applications we build will be specialised to astronomy, the architecture will be applicable to all other knowledge domains.

That looks great. Is that better than the current website text in web/www.myskua.org/index.html
, do you think?
Sorry I've been a bit slow to respond -- it's turning out to be a
quite busy interop.
See you,

I meant that this description is probably more polished than the
description currently in the website tree of the repository, and
perhaps this should replace it.

It looks good to me. Thinking specifically of the questions you
raised (for conversations at poster time):
> 1. how is the semantic awareness of the RDF stores realised?
Possibly as simply as having the knowledge of some relevant
vocabularies built in, so that you can make a SPARQL query involving
skos:broader without having to upload the vocabulary yourself. Hmm:
or perhaps the SKUA node could do that retrievel for itself,
proactively...
There's probably more we could do, but that would be something.

Did we say 'bulk'? I think that would be most of it.

Well, federation and the light semantic knowledge. I suppose part of
the claim is that even a little knowledge goes a long way, but perhaps
just having a few vocabularies knocking about would be a little more
lightweight than would be desirable.
In case it's useful, I've put the current version of my SKUA talk for
the interop at <http://nxg.me.uk/temp/skua-interop.pdf>. This will be
much the same as the ADASS version, and I'll put that in the
repository after I give the interop version tomorrow.

Done.
