I suspect (and hope) 1 & 2 are redundant if you have 3.

>From what I've heard from the w3c eGov list and bits of offlist chat,
it's still early days for getting government data out there. There
seems to be a lot of momentum, but right now it's directed towards
local issues, getting data into a Web-friendly form (I hate to use the
term "legacy", but a lot of the time it does seem to apply - the
source material is buried in a spreadsheet or even a pdf document).
Getting the stuff translated & exposed, linked into the rest of the
world (beyond just shared vocabs) will be phase 2 I expect.

Absolutely.

It's worth noting that for the gov depts to maintain credibility, that
provenance information should be associated with any data exposed - a
minor technical hassle, in most cases likely fulfilled by manual
annotation. (see the Open Provenance Model, if I understand being
RDFized in data.gov.uk http://openprovenance.org/).

A related issue (that Jeni Tennison has raised) is the question of
authority over the statements. I believe she has the right idea, that
to link gov data into e.g. dbpedia, intermediary graphs are necessary,
to ring fence the levels of commitment between the national,
centralised expression of "facts" and those other facts we know and
love from the social-web world.

Your impatience is understandable, but from what I can gather, things
are progressing...

Where? A good idea in principle, but we don't really yet have the
material in place to justify a shared e.g. mailing list.

That sounds reasonable. Anything that can help human discovery can't
hurt machine discovery.

good-o
