Hello Semantics afficionados, <br>
<br>
As you may have heard , there is an on-going effort for updating -
extending the IVOA UCD thesaurus in order to cover Solar data as
well as Planetary data.<br>
<br>
We are currently revisiting the<b> em.line </b>tree structure to
see how to manage the inclusion of new atoms/moleculenames.<br>
<br>
I am asking here data providers , whether they could fill in this
little poll , below .<br>
<br>
1- How many different UCD do you generally use with the <i><b>em.line.'name'
</b></i>( like em.line.CO, f.i. ) structure do you use? <br>
<ul>
<li>more than 50</li>
<li>more than 20 <br>
</li>
<li>more than 10</li>
<li>less than 10</li>
</ul>
<p>2- Could you provide us with a list of the 10 to 15 most used
em.line.* UCD that appear in your data collections ?</p>
<p><br>
This poll is done in order to get an idea about the pratical usage
of the 'em.line.* ' tags .<br>
Thank you for your answers ,<br>
Best wishes , Mireille Louys.<br>
<br>
