S3/SimDAP

[Carlos Rodrigo Blanco]

Hi

First of all, sorry for not having been able to answer this email by 
Herve. When he sent it, I had just went on vacation, and I came back more 
than a month later (and you know... having hundreds of mails to read... 
sorry in any case)

I have looked for that mail and, as I see it, the mail is mostly about 
"good intentions" about trying to find a convergence between S3 and 
SimDAP. The only thing that I can say about that is: "great, it could be 
nice". Although, in fact, I don't know much about SimDAP so I cannot tell 
more. It could be most helpful if you could write some document about how 
SimDAP works (It doesn't need to be a thoroughfull detailed document, but, 
at least, being a protocol: what questions can be sent to a server, what 
kind of answers the server gives... those simple things).

With that we would have something to talk about.

At baltimore I understood that SimDAP was mostly a way to retrieve a final 
document (mostly "give the url of the document") an a prescription on how 
to describe the document content. But I could have misunderstood it.

For instance, I can't imagine the meaning of " the cutout service 
is already optional in the proposal made by Claudio and Rick (cf Rick' 
presentation on thursday) so this is no more a barrier to microsims. "
Why was it a barrier??

In what respects to telecons, I don't like them very much. English is not 
our language in most cases and I'm sorry to say that this problem is 
usually enlarged in telecons specially if we don't know if advance what we 
are going to talk about. I would propose to have: first, some documents to 
study, then some writen discusions in this mailing list and then we could 
maybe have some telecon to discuss the details in a faster way (but having 
studied the subject in advance)

By the way, I think that it would be nice to use this list more often. 
For instance, would it be posible that we have a copy of the document 
about "theory in the VO and those things" (I don't know the title, sorry) 
that was writen recently?

In summary, the idea of collaborating in getting a better protocol sounds 
nice for me (collaborating allways sounds nice to me) but I would need to 
know much more about SimDAP to say something else.

In any case, thanks for the mails from Herve and then Miguel trying to 
reactivate te subject
