Re: Public Data Catalog Priorities and Demand

Thanks Jose for your "two cents" and for the others that reacted my 

To make it clear, I'm quite looking for a standard cataloging format, 
but the human understandable big picture, a visualization or easy to 
grasp categorization/list of typical PSI datasets, maybe a "map of PSI". 
This discussion developes the questions and indicates that there is no 
clear answer to the questions yet. Some more questions...

* How would the "national registry of lakes", "geodata of high voltage 
electric network", "public job vacancies" and "directory of restaurants 
holding licence to serve alcohol" for example relate to the universe of PSI?

* If there is, let's say some thousand, datasets in, is there 
any analysis or wild guesses of how many is missing 10 000, 50 000, 100 
000, 500 000?

* Is there any analysis what is popularily used and what is pure noise 
and not interesting to any developers, democracy advocates or anybody?

I found these two analysis about

Any link to that?

Mind of sharing those 20+ at some wikipage where we could discuss those?
