Registry harvesting frequency

[Petr Skoda]

Dear all

Thank you very much for the prompt action of Christophe - now the record 
is same in all registries seen in VOSPEC and SPLAT. So my personal needs 
are fulfilled for the moment.

However, with the little doubt I suggest to consideration for the whole 
registry WG following:

Do you think that even the update every day is enough for the DYNAMIC 
servis on which depends all the VO functionality ?

If I take the analogy with DNS - after I connect new computer to the 
internet - do you think that the people would like to wait several hours 
(or days) before seeing their computer on-line ?

Why the server  coud not just check the changes in other registries and 
just update the records on a much shorter interval ?

I suppose the enthusiastic model of VO publishing ;-)
When someone goes through the filling of form (and succeeds) to publish 
the service, he will be eager to see his fresh new service everywhere to 
check immediately different applications etc ... He will probably need to 
show the service to other people (with great proud - look at my new 
archive ;-)

And IF he is forced to wait several days (even hours) to see the impact -
it is very discouraging and does not help to advertise the VO in the 
eyes of advanced astronomers (who will register with proud their small 
collections) as the modern dynamic global infrastructure.

Maybe I am too naive - but in my opinion the current registry handling is 
insufficient regarding the role it playes for success of all VO.

That said I would like to encourage people to publish small data sets 
(mainly spectra from smaller telecopes) in VO by emphasising the 
world-wide  visibility" of their observatory - i.e. "if you make your 
archive VO compatible and register it, in few minutes all the world is 
going to query your archive "

I think the success of penetration of VO in everyday astronomy (or common 
goal) is composed from small issues with huge synergic effect. And the 
seamless functionality (and easiness) of the registration process is one 
of those.

I am not subscribing registry WG matters and so far I was not interested 
in registries as I supposed they work seamlessly but to be honest I was 
shocked by disclosure of the real state ;-)
