<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">A recent question came up relating to the use of the ISO Object Identifiers (OID) that we have built into the SANA revisions. The question was related to the use of SCIDs as a unique identifier for spacecraft.
Since SCIDs are not unique (and never were) my suggestion was that the ISO OIDs that we assigned to spacecraft when they request SCIDs should be used. These are truly globally unique identifiers and persist once assigned. They can also be assigned by the
SANA even if a SCID is not requested. How wide this use will be remains to be seen, but that is a separate topic.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">When I went looking for an Internet link to the OIDs that we have defined I realized that while CCSDS has an OID assigned [1.3.112.4], and that could be looked up in an on-line OID registry (<a href="http://oid-info.com">http://oid-info.com</a>),
there was no connection from this CCSDS OID entry to the SANA registries where these detailed CCSDS OIDs were documented. This was a gap and expecting users to navigate from this OID registry, to the CCSDS website, to the SANA, seemed to be too much to expect.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Yesterday I reached out to this OID registry and asked if they could remedy this. They have done that, and in spades. They not only updated the CCSDS registry entry, and added a link to the SANA registries,
but they also included references to the SANA Yellow Books that document the registries. I have attached a snapshot of the current entry in their oid-info.com registry and also one of the SANA page that their link now takes the user to.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">As you can see from their reply, we have control over this information and could, if we wished, send them the whole set of OIDs. We could do this, or we could just send them the top level decomposition, and
use that as a driver of users to our site, which is the authoritative source. I see no benefit is sending them the whole OID set, but do see a potential benefit in sending them the first level decomp, which is the names of the sets: organizations, contacts,
spacecraft, SLE, CSS, S/C, Service Site & Aperture, etc. See CCSDS OID screenshot.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Wanted you all to be aware of this and to have an opportunity to review, comment, and request changes if any appear to be needed.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">And BTW, there are also some Wikipedia web pages for OID that I intend to update as well. Might as well get some added visibility for this. It is public and it is, or could be, of value to others.<o:p></o:p></span></p>

Hi,<br>
<br>
I've updated the description of your OID at <a href="https://urldefense.us/v3/__http:/oid-info.com/get/1.3.112.4__;!!PvBDto6Hs4WbVuu7!a9ORvqdJWwag-cdrWvdRHi4QIUshrQVCXBivv_myv3nY9x6gxxmZ48zT0szYylQTlSAF6Qfk$">
http://oid-info.com/get/1.3.112.4</a><br>
You can <a href="https://urldefense.us/v3/__http:/www.oid-info.com/cgi-bin/manage?oid=1.3.112.4&a=modify__;!!PvBDto6Hs4WbVuu7!a9ORvqdJWwag-cdrWvdRHi4QIUshrQVCXBivv_myv3nY9x6gxxmZ48zT0szYylQTlatOpQTN$">
Modify this OID</a> at any time.<br>
<br>
We don't have a resolution system per se which could be interconnected with other resolution systems. But you can submit a large set of OIDs in an XML file as explained at
<a href="https://urldefense.us/v3/__http:/www.oid-info.com/submit.htm__;!!PvBDto6Hs4WbVuu7!a9ORvqdJWwag-cdrWvdRHi4QIUshrQVCXBivv_myv3nY9x6gxxmZ48zT0szYylQTlSAEbDrX$">
http://www.oid-info.com/submit.htm</a><br>
but we'll implement a tool that will automatically add your OIDs to our OID repository with a hyperlink to their description in the SANA registry. (If you have any issue with this, please reply quickly :-) )<br>
<br>
Thanks,<br>
OID repository admin<br>
