<p>Not Quite. There are two parts (as per the programming tradition). <o:p></o:p></p>
<ol start="1" type="1">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:0in;mso-list:l0 level1 lfo1">
The "Data of Record" (or what Andrew Sullivan calls "Authenticatable Data of Record" in his posting) is the data.<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:0in;mso-list:l0 level1 lfo1">
The data source (SOR or SSoR) is where it is kept, and by whom. <o:p></o:p></li></ol>

<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:0in;mso-list:l1 level1 lfo2">
The Data of Record (DOR) is authoritative because it comes directly from the agreed upon system of record (SOR), (e.g. ICANN, or a trustee)<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:0in;mso-list:l1 level1 lfo2">
Other data sources within the Internet ecosystem (cashed data, extracted data, etc.) is not equivalent to Data of Record and "user be(a)ware"<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:0in;mso-list:l1 level1 lfo2">
Data errors are a separate issue (errors in collection, transcription, or deliberate) with complaints going to the data gatherers (Registrars/ISPs, etc.)<o:p></o:p></li></ul>
<p class="MsoNormal" style="margin-bottom:12.0pt">Of course, as to be expected, the system of record (SOR), the users, and the data gatherers would be engaged in ongoing dialogue to deal with data quality issues.<br>

<pre>I am a big fan of “Keep it Simple” and would go the tradition within data management. There, what here could be called the “Data of Record”<o:p></o:p></pre>
<pre>(DOR) comes from a system of record (SOR) or source system of record (SSoR).<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>That makes a particular information management storage system (Registries? ICANN? Trustee?) the authoritative data source. The data is referred to as the Data of Record (DOR) and is the relevant “gold standard” data whenever there is a conflict, say with cached data. The DOR from the authoritative data source rules.<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre>I note that what is authoritative here is the data source. Should there be errors in the data because of ISP/Registrar errors, or fraud, that is a separate issue and the authoritative data source is not on the hook for errors in the data, unless they caused them.<o:p></o:p></pre>
