Yep :)

Interesting questions - and I started writing a long reply addressing it,
but I'm stopping to ask "how do you mean "relates to" - as in where it
would sit? How it would be classified?

I'd say most, but that there is probably not as many as you'd think. And
I'm including* in that. (We have to as a group remain
international in focus :) ) Many seem to include "views" of data in the
term "missing datasets" - I think that if one could identify what datasets
are primary (something I'll expand on once I find what you meant above),
then we could generate a lot of other datasets from these. I guess what
I'm saying is its probably just as important to ask how many datasets out
are dependent on other datasets for their data.

I know in Australia there is - it's something our Bureau of Statistics
looks at. From memory, GIS, Labour Market and Population data are popular,
as is weather information. I'd say it's all interesting to someone. "If
you build it they will come" - ie: What would be popular if people were
able to use any dataset, if they could, or knew how, or knew what to use
it for? Prehaps its just that developers and others haven't come up with
good applications for the data yet.

Looking at Jose's reply below btw - in Australia the "most important" PSI
based on citizen usage of services using the PSI is Weather information.
Followed by (in no order) Tax, Employment and Social Security. Combined
with Spain its not much, but I'm betting that if you got similar
information from other places you'd see a pattern emerge: people are
interesting in information that affects them.

Its like there is a lack of interest data as information for the greater
good, such as the country (any more than they care about the sources and
background of the headline story in the news. They read the story, they
get passionate, they buy a latte and talk about it for 15 minutes with
friends. They go back to work - they don't generally start their own in
depth expose on the story.). There is an assumption that there is someone
out there who knows what to do with that data and is paid well to do so.
And that eventually the important bits will filter down into something
that the individual can use.

Generally they (for instance) won't be interested in things such as
migration rates, annual rainfall, or leading economic indicators, so much
as "Where do *I* get a job", "Will it rain on *my* party this weekend" or
"Can I get a rebate for this on *my* tax" etc.

However when drilling down to this personal application of data, I think
there will always be a need to leverage off that top level primary data
that comes across as "pure noise" in some cases because the uses for it
aren't immediately obvious.

Is it possible or feasible to "weight" datasets as to what is important
and what is not? Does popular = important? Personally I think it's all
vital, and the concept of openess and transparancy means ultimately, where
possible, it all needs to go up, regardless of if it gets used regularily
or not.

(Thought for the day? : Only one person may ever look at a dataset
relating to GIS data and observatories for instance, but that one person
might be Stephen Hawkings, and that one use of that one dataset by that
one person might change the world.)
