Dear HiPS contributors and providers (and IVOA Apps and registry
members)<br>
<br>
For helping to the HiPS IVOA standardization decided at Sydney, we
need to homogeneize as far as possible the AUTHORITY ID of the HiPS
identifiers (IVOID) in order to reuse the AUTHORITY IDs already
defined in the VO registry or to create the missing AUTHORITY IDs in
the VO registry.<br>
<br>
For a HiPS, the AUTHORITY ID is the first word in the
"publisher_did" field provided in each HiPS properties file (HiPS
v1.3 specification ex: <a class="moz-txt-link-freetext" href="http://alasky.unistra.fr/SUMSS/properties">http://alasky.unistra.fr/SUMSS/properties</a>).<br>
For retrieving the AUTHORITY IDs already defined in the VO registry,
use this URL:
<a class="moz-txt-link-freetext" href="http://registry.euro-vo.org/result.jsp?searchMethod=XPathQLSearch&select=%23ResourceType%23%3D%27Authority%27">http://registry.euro-vo.org/result.jsp?searchMethod=XPathQLSearch&select=%23ResourceType%23%3D%27Authority%27</a><br>
<br>
The comparison of both lists suggests these actions:<br>
<ul>
<li><font color="#000099">ivo://SSC/... => to be substituted in
HiPS properties file by: ivo://xcatdb/...</font></li>
<li><font color="#000099">ivo://CADC/... => </font><font
color="#000099"><font color="#000099"> </font><font
color="#000099"><font color="#000099">to be substituted in
HiPS properties file</font></font></font><font
color="#000099"><font color="#000099"><font color="#000099"><font
color="#000099"><font color="#000099"> by</font></font>: </font>
</font>ivo://cadc.nrc.ca/...</font></li>
<li><font color="#000099">ivo://CDS/... => to be substituted in
HiPS properties file by: ivo://CDS.Aladin/... and
ivo://CDS.VizieR/...<br>
</font></li>
<li><font color="#000099">ivo://IRAP/... =></font><font
color="#000099"><font color="#000099"> </font><font

HiPS properties file</font></font></font><font
color="#000099"><font color="#000099"><font color="#000099"><font
color="#000099"><font color="#000099"> by</font></font>: </font>
</font> ivo://ov-gso/...</font></li>
<li><font color="#990000">ivo://arches/... => to be created in
the VO registry</font></li>
<li><font color="#990000">ivo://AMIGA/... => to be created in
the VO registry</font></li>
<li><font color="#006600">ivo://ESAVO/... => ok (ivo://esavo is
already VO defined)</font></li>
</ul>
I am preparing a perl script processing these substitutions for a
whole HiPS node (local HiPS and eventual mirror copies for avoiding
to resynchronize whole HiPS clones) based on a simple list of HiPS
paths. <br>
<br>
May I suggest to all current HiPS providers to:
<ol>
<li>Check the substitution proposal, validate my suggestion, or
provide an alternative.</li>
<li>Do the substitions in your own HiPS properties files (or ask
me to use my perl script in order to do it more easily)</li>
<li>Create the missing AUTHORITY ID in the VO registry if required
=>
<a class="moz-txt-link-freetext" href="http://registry.euro-vo.org/insert.jsp?identifier=esa://empty.doc/Authority&action=new">http://registry.euro-vo.org/insert.jsp?identifier=esa://empty.doc/Authority&action=new</a></li>
</ol>
<p>As far as I know these modifications can be done immediately
without breaking the HiPS existing clients access (Aladin Lite,
Aladin Desktop, VAO portal, MIZAR, ...)<br>
