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.

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.
