<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I don't see Michele's request for L05 and your request for a generic XBT entry in L22 as mutually exclusive. </p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I think Michele needs to distinguish XBTs and MBTs in CDI records, which are marked up using L05 rather than L22. This needs the L05 extension unless Michele is happy to use the XLINK mechanism to link to L22 concepts
even though this isn't searchable through the CDI interface. </p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Michele, have I understood this correctly? Could you please confirm that you still want the new L05 entries?</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">A generic XBT entry could be set up in L22. I don't like generic entries because they encourage short-cuts when creating metadata. It's much easier to use a generic concept than do the research necessary to obtain a more
precise description of the data production tool. However, I do concede that there are times when no amount of research will provide the necessary information and a generic concept has to be used. A note to all is that this should be considered as a last resort.
There are times - such as drop-rate equation corrections - where detailed knowledge of the XBT type is important. </p>

<div dir="ltr">Dear All,
<div><br>
</div>
<div>would it be possible to keep L05 as iti (bathythermographs) and save the information on "expendable bathythermographs" in L22 vocab, possibly adding a new general term like"Generic XBT" (following the example for the L22 code labelled "TOOL0001")?</div>
<div><br>
</div>
<div>This new L22 term would be useful for our needs.</div>
<div><br>

<div>Many thanks in advance,</div>

<p style="margin-top:0; margin-bottom:0">A couple of suggestions here. </p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">First, the new terms should be mapped to the existing term within NVS. </p>
<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">Secondly, in an ideal world semantic reasoning when searching metadata would cause records marked up with the new terms to be selected when searching for 'bathythermographs'. To my knowledge we haven't got this functionality
so it might be a good idea to include 'bathythermographs' as well as 'expendable bathythermographs' when marking up XBT metadata.</p>

<p class="x_m_7512662570379014406x_MsoNormal">I would like to propose two new L05 categories. In a similar manner for CTDs, they are more granular terms for bathythermographs (132). This is to help our users distinguish between XBTs and MBTs:</p>

transferred to the platform by a wire that breaks when the wire is out. Depth is calculated as a function of time to descend and a known constant rate of descent.</p>
