Dear Exec,
please find a summary of the activities of the VOQL group since last
Interop meeting (Sep 2007).
The group has mainly concentrated (as agreed) on the ADQL Document. As
you can see, our estimation to initiate the RFC at the beginning of
the year could not be fulfilled as there were issues under discussion
that required our full attention. However, I am very glad to report
that we tried to cope with all issues, and we managed to start the RFC
at the beginning of March, allowing us to come to this interop meeting
with a very complete ADQL document, which I am sure we'll manage to
agree on.
I would like to thank from here the excellent work from the VOQL-TEG
Group, and the people inputing comments to the RFC pages, helping us
polish the latest bits of the document.
I have attached (in-lined), for your information, the relevant mails/
docs accompanying each of the milestones that I am describing below,
should you want to look at them.
I remain at your disposal for any question you might have.
Best regards, and see you in Trieste.
Pedro Osuna. Chair, IVOA VOQL Group.

Subject: Latest ADQL doc and proposal for evolutioin
Reply-To: Pedro Osuna <Pedro.Osuna at sciops.esa.int>
Dear all,
there has been a great deal of work behind the scenes by Pat, Inaki,
Jeff and Alex to try to define the Region, as we agreed some time ago,
and during our last Cambridge meeting.
The process has not ben easy at all, but I believe we are in a
position to expose to the whole VOQL community a mature document that
could be proposed for PR in the coming month.
We are still lacking the text for the Region stuff within the
document, which we agreed will be written by two native Enlgish
speakers (Pat and Jeff) with support from Alex and Inaki if needed.
Nevertheless, we do have a neat BNF (which is the most important
thing) written by Inaki and Jeff, and this is what will form the basis
for the ADQL.
I would like you -voql-teg- to review the document and give your
comments, and whether you are happy enough so it goes to the general
VOQL community.
I attach the latest document produced by Inaki and inline his
description of the latest changes in the document. Please let us know
your comments if any. I will call for a teleconf meeting once you have
had time enough to read the document.
I want to thank here Inaki, Pat, Jeff and Alex for their hard work ont
he Region issue.
Cheers,
P.

Subject: Next TCG Meeting on Wednesday
Reply-To: Pedro Osuna <Pedro.Osuna at sciops.esa.int>
Dear all,
next Wednesday, there will be a TCG teleconf where I will report on
the status of the VOQL group.
I will say that we are near to completion, and that very soon a
finalised ADQL standard (with the region text and a possible
implementation from Benjamins comments) will be distributed to the
whole VOQL group, and then start the standard RFC period.
Just for your information.
Cheers,
P.

Subject: Latest ADQL Document version
Reply-To: Pedro Osuna <Pedro.Osuna at sciops.esa.int>
Dear all,
please find attached the latest version of the ADQL document.
This version will be distributed to the overall VOQL group next
Tuesday, after the Easter Holidays, and is intended to be the final
version for an eventual Proposed Recommendation.
It includes a vast amount of work done on the Region definition mainly
by Pat Dowler, Jeff Lusted, Alex Szalay and Inaki Ortiz. I just wanted
to publicly thank them for this huge effort.
Please read the document in detail, and let us know if you have any
comment. In any case, after it goes to the VOQL group we will still be
able to do minor changes on it.
Thanks very much.
Cheers,
P.

Attachment 5: Announcement of latest ADQL within the global VOQL
community to receive comments during 4 weeks
From: Pedro Osuna <Pedro.Osuna at sciops.esa.int>
Date: 26 de marzo de 2008 11:14:01 GMT+01:00
To: voql at ivoa.net
Subject: Latest ADQL Document and roadmap for Proposed Recommendation
Dear all,
please find attached the latest ADQL Document version produced by the
VOQL-TEG.
I would like to start the formal RFC period in around 3-4 weeks from
now, so should you have any comments by now, please let us know as
soon as possible.
The formal RFC spans for another 4 weeks, so if everything goes well
we would be able to have the ADQL Document as a Proposed
Recommendation just by the next interop meeting at Trieste.
I would like to thank thoroughly the VOQL-TEG group for their effort
in this specification, but very specially Pat Dowler, Jeff Lusted,
Alex Szalay and Inaki Ortiz for the very tough work during the latest
steps in concluding the ADQL Doc.
Should you have any comments, please don't hesitate to send them.
Thanks.
Cheers,
P.

Subject: RFC initiated for Astronomical Data Query Language
The Astronomical Data Query Language document is now an IVOA
Proposed Recommendation. A 1-month Request For Comments period
has been initiated, with the goal of advancing ADQL to an IVOA
Recommendation.
A 1-month Request For Comments period on the draft ADQL V2.0
specification has therefore been initiated. Please review the
specification, and add any comments to the RFC page at
http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/ADQLv2RFC
More extensive discussions should be directed to the VOQL working
group mailing list (voql at ivoa.net). The most recent version of the
ADQL specification can be found at
http://www.ivoa.net/Documents/PR/ADQL/ADQL-20080430.pdf
Please submit any comments by 30 May 2008. Thanks in advance for
your contributions.
Pedro Osuna.
Chair, IVOA VO Query Language Working Group
