>From my point of view of CS provider (Skybot service), the key point is the addition of the EPOCH parameter. Without this parameter, a solar system CS service is unusable, as Skybot is in the next release of Aladin. Moreover, with the coming of big catalogs such as Gaia, this parameter will become mandatory to query the sky at a given epoch. One of my ongoing project is to seek for solar system objects in the "Carte du ciel" plates, thanks to the Gaia catalog which will allow one to get star positions at the beginning of the XXth century with an accuracy equivalent to Hipparcos today. Without the EPOCH parameter it will not be possible to cross-match stars 100 years back from the reference epoch of the catalog.<br>

Dear all,<br>
at the oncoming Interop in Santiago I will give a quick status report<br>
on the Simple Cone Search revision task.<br>
<br>
I just fixed a couple of sentences and typos in the internal WD built<br>
in July and I attach it here for you.<br>
<br>
Discussion points are still the same.<br>
I would say that<br>
1 - ReST vs. query_param access_url<br>
2 - RESOURCE type="results" and multiple RESOURCEs<br>
3 - minor vs. major revision<br>
<br>
are the main ones, while<br>
4 - trying or not to use UCD1+<br>
<br>
can be left out until/if we tackle number 3.<br>
<br>
As for the "§2.3b INFO element error validation" issue, I set up an<br>
Erratum that should take care of it<br>
(<a href="http://wiki.ivoa.net/twiki/bin/view/IVOA/SCS-1_03-Err-1" rel="noreferrer" target="_blank">http://wiki.ivoa.net/twiki/bi<wbr>n/view/IVOA/SCS-1_03-Err-1</a>).<br>
<br>
The full view on Cone Search is available starting at<br>
<a href="http://wiki.ivoa.net/twiki/bin/view/IVOA/ConeSearch" rel="noreferrer" target="_blank">http://wiki.ivoa.net/twiki/bin<wbr>/view/IVOA/ConeSearch</a><br>
<br>
Every comment and contribution is welcome and appreciated.<br>
I especially ask cone search providers and apps developers<br>
to join this task to update this block of the DAL landscape.<br>
<br>
Cheers,<br>
Marco<br>
<br>
PS - this is a DAL internal WD, but Apps is alerted for obvious reasons<br>
PPS - detailed revisions can be followed also on volute<br>
